Point Reyes Lighthouse Trail

Point Reyes Lighthouse
The Point Reyes Lighthouse stands on a small platform on top of windblown rocks. Expect salt-spray and fog. In this harsh environment only specialized plant species survive. An interpretive panel tells us:
The wife of a lighthouse keeper once planted a small garden nearby, but with no success. As soon as the carrots sprouted the wind blew them away. Few plants can face up to the ocean's harsh influences.

On a foggy morning, your approach to the Lighthouse Visitor Center may include a short walk under water-dripping cypresses.

On an outside wall at the visitor center, you will find an offshore map showing the undersea topography of the continental shelf with Cordell Bank, Rittenburg Bank and Noonday Rock.

Skull of a gray whale
On their spring migration, California gray whales (Eschrichtius robustus) pass Point Reyes close to shore and—when the fog lifts—you can see spouting whales breaking through the ocean surface over the shelfscape. The skull of a female gray whale, found in February 1985, is on display next to the Point Reyes Conglomerate peak.

Steps alongside conglomerate
After passing the conglomerate outcrop,  you will find yourself on top of the stairway with 300-plus steps. The stairway sometimes is closed when winds are getting too strong to descend/ascend safely. Gusts exceeding 100 mph have been recorded. A panel summarizes the lighthouse history:

Point Reyes Light has guided and cautioned mariners along this hazardous coast for over 100 years. Built by the U.S. Lighthouse Service in 1870, it came under management of the U.S. Coast Guard in 1939. Resident personnel operated the station until 1975 when the conversion to automated lights and electronic equipment was completed.

The National Park Service maintains a very detailed Visit the Point Reyes Lighthouse site, which further highlights the lighthouse history and links to information on accessibility and road-closure/shuttle-bus policies during whale-watching season.

Getting to the lighthouse trailhead

From Olema or the Bear Valley Visitor Center, drive north on Bear Valley Road and turn left at its junction with Sir Francis Drake Boulevard. Follow Sir Francis Drake Blvd. for about 20 miles to its end—first northwest along the western shore of Tomales Bay to Inverness, then westward over the Inverness Ridge and finally southwest through the Pastoral Lands.

Don't miss Chimney Rock!

Returning from your lighthouse visit, you may want to explore the east-side spur of the headlands by hiking through grassland, enjoying views of Drakes Bay and overlooking surf-zone rocks such as Chimney Rock and the natural bridge at the end of Chimney Rock Trail. To do that, turn right on Chimney Rock Road (before passing again through the “A” Ranch). Find the parking lot and trailhead after about one mile from the Sir Francis Drake Blvd./Chimney Rock Rd. junction.

Point Reyes Conglomerate

Outcrop of Point Reyes Conglomerate
Point Reyes Conglomerate is exposed on the Point Reyes peninsula. It can be found at the end of the Chimney Rock Trail around the overlook of Chimney Rock and the cliff arch. Next to the Lighthouse Visitor Center—at the other tip of the ocean-surrounded headlands—the conglomerate formation is exposed next to the lighthouse trail (shown above and below). There, on a display panel, and also on a web page it has been described with the following words [1,2]: 

The intriguing rock exposure in front of you is part of a formation that caps the highest hills in this area. The Point Reyes Conglomerate is a formation consisting of a sandy matrix embedded with pebbles, cobblestones, and boulders. Geologists estimate that the formation may be over 50 million years old.

Using less formal terminology, the conglomerate has been described as geologic cookie batter [3].

Watch out for similar conglomerate outcrops and sandstone features while taking a rest on your way down to or up from the lighthouse plateau.

Chimney Rock Trail

Map of the Point Reyes headlands with Drakes Bay and Chimney Rock 
Chimney Rock Trail is a short Point Reyes headlands trail between Drakes Bay and the Pacific Ocean around the Farallon Islands. As you can see on the map above, several rocks and sea stacks dot the south-side coast of the eastern spur of the headlands. Chimney Rock is one of them. To get to the overlook, from where you can see Chimney Rock and the nearby natural bridge, follow the well-marked path from the trailhead (red arrow) to the end of Chimney Rock Trail.

Point Reyes Lifeboat Station
Historic Lifeboat Station (Drakes Bay)
Several social trails lead close to the edges of steep cliffs of mostly Point Reyes Conglomerate, which frequently crumble and slide. Keep a safe distance! On your return walk, you may want to take Underhill Trail to get a close-up view of the historic lifeboat station, constructed in 1927. An interpretive panel at the trailhead “introduces” one of the U.S. Coast Guard crews commissioned to save ships and lives:

These seemingly ordinary men were the heroes of this coast. Like the men who served before and those who served after them, surfmen risked their lives to save mariners in distress. They were always on duty, always prepared and always willing to sacrifice.

Surfmen prepared to save mariners in distress
On your final steps back to the parking lot, you will pass through a residence. You will find a plaque in the wall at the property's south entrance commemorating Francis Drake—an earlier “hero of this coast”—who landed on these shores on June 17, 1579 and took possession of the country, calling it Nova Albion.

How did these shores look then? Were the natural bridge and Chimney Rock already pounded by waves and what were their shapes?

Getting to the Chimney Rock Trailhead

From Olema or the Bear Valley Visitor Center, drive north on Bear Valley Road and turn left at its junction with Sir Francis Drake Boulevard. Follow Sir Francis Drake Blvd. for almost 20 miles and turn left on Chimney Rock Road after passing through the “A” Ranch. Find the parking lot and trailhead after about one mile at the end of this narrow two-way road.

If you are on your way back from a Point Reyes Lighthouse visit, turn right at the Sir Francis Drake Blvd./Chimney Rock Rd. junction before getting to the “A” Ranch.

The “outer loops” in Sycamore Grove Park

Horses off Harrier Trail in Sycamore Grove Park
The outer loop trails in Sycamore Grove Park include Valley View Loop, Cattail Pond Loop, Meadowlark Loop and Harrier Trail. Whereas the inner loop trail—the Winery Loopleads around flat grasslands and orchards, the outer loop trails traverse mostly open hillsides with various vista points.

You can access those loops via Wagon Road Trail. Ascend the less steep branch of the Wagon Road Trail loop near the junction of the Winery Loop and Walnut Trail. This shaded, east-heading incline takes you above the Olivina winery ruins with views of the partially overgrown rubble inside the buildings that once were used to produce olive oil, wine and brandy.

Harrier Trail post
Post at Valley View Loop/Harrier Trail junction
Continuing south on Wagon Road Trail, you will pass another historic site, a pair of palm trees and then meet the Valley View Loop. Turn left on the loop trail and after half a mile you will arrive at the Harrier Trail post. Harrier Trail is a path traversing meadows next to an olive orchard and the Veterans Administration Hospital. The Harrier Trail incline past the row of tall eucalyptus trees alongside the hospital property leads to an unnamed loop. Either way you eventually will end up on Valley View Loop again.

The Valley View Loop summit features an excellent vista point with views of the Livermore area and Mt. Diablo farther north. Back on Wagon Road Trail, go west to Cattail Pond. You may see western pond turtles on the tiny rafts floating in the pond.

If not yet loop-tired, you still have the Cattail Pond Loop and Meadowlark Loop ahead of you, but they can be skipped by just taking the Wagon Road Trail back and downhill to the “lowlands” of the Arroyo del Valle.

Winery Loop Trail

The Winery Loop Trail is a 2.7-mile-long hiking and biking loop around the grasslands south of Arroyo del Valle in Sycamore Grove Park, five miles south of downtown Livermore in California. Trail highlights are the ruins of the historic Olivina Winery and the sycamore with a hole—the Hobbit Tree.

About a quarter mile south of the parks's Wetmore Road entrance, the trail follows a vineyard fence for another quarter mile to its junction with the 0.3-mile-long Olivina Trail. While you continue on the Winery Loop, you will soon arrive at an intersection, from where the 1.5-mile-long Wagon Road Trail ascends the hillscape and the 0.2-mile-long Walnut Trail offers a shortcut back to the streambed and Wetmore entrance. Past the intersection, the loop trail skirts the fenced ruins of the Olivina distillery and winery.

As you come to the junction with Kingfisher Crossing, you get another chance to shortcut the loop. If you do the complete loop, you will now travel between orchards: an olive orchard to your right (not part of the park) and a neglected almond orchard at the turning point of the loop. Here, the Winery Loop Trail meets the 2.5-mile-long Arroyo del Valle Regional Trail, which connects the Wetmore Road entrance with the Arroyo Road entrance

The Hobbit Tree in Sycamore Grove Park

“Teapot view” of Hobbit Tree
The Hobbit Tree is an old sycamore tree in Livermore's Sycamore Grove Park.You can get to the tree by walking for about half a mile from the park's Wetmore Road Entrance on Arroyo del Valle Regional Trail to the trail's junction with Olivina Trail. The Hobbit Tree stands between the trail and the streambed. The site includes two benches.

Doorway and hole of Hobbit Tree
The hollowed-out sycamore houses various creatures. Hobbit-size humans find it easy to walk inside the tree through a narrow doorway or slide down to there through the oval hole. I found myself tall enough to simply look through the hole. Doing this from the Arroyo del Valle side, I got a peekhole view of the grasslands and the hills that backdrop the Olivina Winery ruins—historic structures, but younger than the Hobbit Tree. 

In a recent Bay Nature article, Sylvia V. Linsteadt shares her Hobbit Tree knowledge and discoveries:

I stopped on the Olivina Trail to visit an old sycamore known to park personnel and visitors as “the hobbit tree.” It's not hard to see why—from the outside, the tree resembles a fantastical teapot with a window, and what's more, it's partially hollow, with an arching doorway that opens into the tree's interior. Someone placed a stump just inside, and I sat there for a long time, looking up into the sycamore's hollow trunk, into darkness, trying to imagine the life of such a tree, roots down in the alluvial gravel of the old Arroyo del Valle, tall branches clattering in the breeze and home to countless birds, insects, and mammals.

Sycamore Grove Park south of Livermore, California

A sycamore with a view: Hobbit Tree peekhole
Sycamore Grove Park is a small semi-urban park surrounded by neighborhoods, wineries and orchards. The ruins of the old Olivina Winery can be found within this open-space park with its many loop trails. Hiking, bicycling and horseback riding trails traverse sycamore and oak woodland as well as grasslands. Unpaved roads and single-track paths over hilly landscape offer varying vistas of the valleys and mountains of the Diablo Range, including the Mt. Diablo Summit and North Peak north of Livermore. If you enjoy relaxing in riparian habitat, you may just want to stroll along the trails on either side of the willow-lined Arroyo del Valle, which runs through the park.

Sycamore bark patchwork
The park is named for California's native western sycamore trees that you can explore on the brookside plains. Platanus racemosa (family Platanaceae) trees grow over 100 feet (35 m) tall. Trunks commonly divide in two or more strong trunks. The bark typically builds a patchwork of white, gray and beige layers. Older and darker bark slowly peels away.
Arroyo del Valle seen from Magpie Loop Trail
The Hobbit Tree, a hollow tree with a look-through hole, is the most popular sycamore in the park and a fun site for photo shoots. Sylvia Linsteadt explains that western sycamore trees can live for hundreds of years and that the oldest tree sprouted in what is now Sycamore Grove Park some 300 years ago [1]. Describing the grand old sycamores amid flat grassland on either side of the Arroyo del Valle streambed, she writes about the once common, now rare sycamore alluvial woodlands in California:

Such wide, graveled banks are a classic feature of sycamore alluvial woodland, and they're integral to the tree's health and longevity. A distinct and vital ecosystem in California, sycamore alluvial woodland is characterized by summer-dry streambeds that branch and braid out through the sandbars, silt, and gravel beds deposited by winter rains and floods. [...]. Livermoore's Sycamore Grove Park is among the few preserved alluvial woodlands left in the East Bay, and as such it provides us a window into an older California.    

The flooding that occurred during the 2016/2017 winter rains hopefully boosted the revival and healthy growth of those sycamores that had been damaged in drought years.

Getting there
Sycamore Grove Park has two main entrances (a few miles south from downtown Livermore): the Wetmore Road entrance at the park's northwest end and the Arroyo Road entrance at the southeast side, not very far from the Del Valle Regional Park entrance.
Wetmore Road Entrance
To get to the Wetmore entrance, drive west (best on 1st Street) from downtown Livermore to get on Holmes Street. The latter takes you south and continues as Vallecitos Road. Turn left on Wetmore Road and, after 0.3 miles, find the park entrance to your right.
To get to the Arroyo entrance, drive south on S L Street from downtown Livermore. S L Street continues as Arroyo Road. After passing the Arroyo Road/Wetmore Road junction with the historic Olivina Gate, follow Arroyo Road for another 1.5 miles and find the park entrance and ranger station to your right across the Wente Vineyards.

Grass Lake Trail: from Lily Lake to Grass Lake in the Desolation Wilderness

 Grass Lake

From the Glen Alpine trailhead at the north side of Lily Lake, a westbound gravel road leads past private cabins and decaying buildings to the Glen Alpine Springs Historical Site, located one mile from the trailhead. Interpretive displays explain the history of the site and illustrate how its resort structures once looked. 

At a junction 1.6 miles from the trailhead, Glen Alpine Trail continues northwest to Mt. Tallac, Half Moon Lake and Susie Lake, while the 1.1-mile-long Grass Lake Trail veers southwest to Grass Lake. Soon you will leave the riparian forest into a more open, glacial granite landscape with scattered conifers. At one point, you need to cross Glen Alpine Creek. A log across the creek comes in convenient to hold on in case the step-rocks are slippery.

Fractured rock structure near Grass Lake
Beyond this crossing, the single-track trail remains its gentle uphill path through small canyons and around fractured granite structures, occasionally covered with pinemat manzanita or with a few trees on top. The granite scenery continues at Grass Lake. Although the lake has some shallow corners with grass growing on its shore, the overall appearance of the lake is dominated by the granite rocks and cliffs surrounding it.

Getting to the Glen Alpine trailhead

The trailhead is located at the end of a narrow, paved one-lane road south of the Tallac Historic Site. From Highway 89 (about one mile west of Camp Richardson), turn onto Fallen Leaf Lake Road. Follow the road along the entire length of Fallen Leaf Lake. Be prepared to stop to let oncoming traffic pass. Also watch for pedestrians, bicyclists and dogs, especially while passing  the lakeside homes and cabins. Past the fire station at the far end of the lake (about 4.5 miles south of Hwy 89), follow the road as it winds uphill. Find parking after crossing a bridge over Glen Alpine Creek.

Majestic Oaks Trail: a short trail through the oak forest of Caswell Memorial State Park

Oak forest of  Caswell MSP in California's Central Valley
Oak forest of Caswell Memorial State Park in California's Central Valley

Majestic Oaks Trail is a short hiking trail through dense oak forest. This less-than-a-half-mile-long trail connects with Fenceline Trail and Gray Fox Trail and intersects with River Bend Trail in Caswell Memorial State Park, California. Some of the majestic valley oak trees in the park are said to be more than 60 feet tall and can have a circumference of up to 17 feet. Wild grapevine is taking over the underbrush—and in many places is trying to reach for the higher branchwork as well.

The spreading oak forest canopy is amazing. You are in an oak jungle. To appreciate the size of a single valley oak, see the broad-crowned oak tree in the Cosumnes River Preserve, another small Central Valley park, in which old valley oak trees are preserved and new ones are planted to keep the Valley alive with valley oak.

Caswell Memorial State Park: shaded trails through an ancient forest

Wild grapevine drapings in Caswell Memorial State Park
Caswell Memorial State Park is a preserve of riparian woodland six miles southwest of the city of Ripon in San Joaquin County in California's Central Valley. The east- and south-side boundary of the park is the meandering Stanislaus River with its bends and sand beaches.

Grapevine branches hanging over Gray Fox Trail
The riverside park stands as an example for a mature oak riparian forests; now rare, but once much more prominent in the valley landscape. The most striking feature of the park is the ancient forest —actually, most of the preserve consists of dense forest. Tall oak and cottonwood trees grow here, many of which have been conquered by wild grapevines with hanging and swinging branches. Numerous shaded trails loop around interesting forest sites and some provide access to vista points alongside the Stanislaus River.

Stanislaus River
River Bend Trail vista: Stanislaus River at river bend
The riparian ecosystem is teeming with wildlife. Racoons, foxes, skunks, weasels and squirrels live here. The smaller riparian brush rabbits and riparian wood rats have their burrows or nests in the thick understory—hidden, but still not completely safe from predators. Jordan Summers writes about these small mammals [1]:

Sitting at the bottom of the food chain, they are meals for raptors such as great horned owls, osprey, and Swainson's hawks; they are also on the menu of all the mammals listed above; and they are even taken by snakes. No wonder they live in seclusion.

Park history

The plaque at the park entrance says that Caswell Memorial State Park was donated in memory of Thomas Caswell (1843-1921), early day rancher and humanitarian, and his sons Wallace Caswell and Henry Caswell. The park brochure shows a picture of Thomas Caswell on his Modesto ranch and provides further details:

Seven hundred acres [2.833 km2] of riparian forest along the river were purchased by Thomas Caswell, a farm equipment manufacturer and rancher, in 1915. In 1950 the Caswell family created a legacy for the people of California by donating 134 acres [0.542 km2] of forest to be preserved as a state park, so future generations might experience the valley in its original natural state.

Getting to Caswell MSP

The park address is: Caswell Memorial State Park, 28000 South Austin Road, Ripon, CA 95366. Phone: (209) 599-3810.
From downtown Ripon head west on West Ripon Road. Turn left on Austin Road and drive south. The road leads into the state park. An entry fee has to be paid at the kiosk. After continuing for less than half a mile on the shaded road to its dead-end, the parking lot, rest rooms and picnic tables are found on the left side.

River Walk Trail in Cosumnes River Preserve

Cosumnes River
Cosumnes River, Central Valley, California
The Cosumnes River Walk in the Cosumnes River Preserve includes trails along the Middle Slough and loop trails with access to the Cosumnes River. The trails will lead you through grasslands and riparian forest. You are invited to combine various trail loops into your overall path. If you are headed to what is called “The Point”—a scenic place from where you can see the Cosumnes River and the entrance to Tihuechemne Slough— your round trip will be at least three miles long. A Nature Trail Guide with a trail map is available at the visitor center

From the preserve's visitor center your walk will start like the Wetlands Walk over the bridge with the beautiful, often overlooked plaque illustrations of animals and plants. Instead of turning left for the Wetlands Walk, turn right to stroll south alongside Middle Slough. The water in the slough may look stagnant, but, since it is connected with San Francisco Bay via the Delta waterways, it has a slow in-and-out flow: Middle Slough is a tidal slough influenced by the bay tides.

The Guide features many points of interest including the majestic valley oak, growing in the oak savannah to the left of the tracks of the Union Pacific Railroad. You'll find a variety of other plants such as live oak (less common to the preserve), willow, native and non-native blackberry, wild California rose, Santa Barbara sedge, cattails—and, yes, poison oak.

Leaves of three, let it be!
Alongside the Cosumnes River you will find a few points with small openings in the riparian forest enabling riverside bird-watching. Seasonally, great blue herons and egrets roost and feed here. The visitor center handout with the title Cosumnes River Preserve describes the origin of the eponymous river as follows:
Just over 80 miles long, the Cosumnes River begins in the great Sierra Nevada mountains, deep in El Dorado National Forest. Its head waters rest at an elevation of 7,600 feet and the river is fueled mostly by rain runoff and some snowmelt. The three forks of the Cosumnes flow through lush conifer forests and tumble over the huge rocks of granite canyons. As the river drops into the drier foothill environment, it coalesces into one channel. Oaks and gray pines dominate the landscape.

In the Central Valley the river slows its flow and feeds the aquifer below. Less than a mile away from the preserve's slough and river trails, the water of the Cosumnes River joins that of the Mokelumne River on its way into San Francisco Bay.

Wetlands Walk Trail in Cosumnes River Preserve

Potato-shaped gall growing on valley oak tree
Wood duck illustration on bridge plaque
At the north side of the visitor center of Cosumnes River Preserve is the trailhead for the Cosumnes River Walk and the Wetlands Walk Trail. A bridge with metal plaques on its handrails, illustrating local animals and plants, crosses Willow Slough. Turn left when you get to the open land with rail tracks in view.

Bridge over Willow Slough
Turn left again at the next junction, from where another bridge (see picture) takes you across Willow Slough to an “orchard” of valley oaks: these trees were planted by preserve volunteers in 1988. They are much younger and smaller than the majestic valley oak you will encounter while exploring the River Walk Trail farther south.

At the branches of some oak trees you will notice yellowish brown or dark brown galls—often ball-shaped, occasionally potato-shaped like the one shown above. They develop when wasps lay their eggs in the bark. I saw  numerous valley oak trees with dense clusters of galls. Judging by tree appearance they do not harm the growth or well-doing of the trees.   

The valley oak trees populate most of the area north of the slough between the railroad tracks and Franklin Boulevard. The trail loop intersects with Franklin Boulevard and continues southwest toward the boardwalk and back to the visitor center. At the end of the half-mile-long boardwalk you will find a viewing platform. Wildlife viewing here is most interesting when the ponds are flooded and the area turns into wetland, providing opportunities to see ducks, geese, swans and shorebirds. Wading birds such as ashy gray sandhill cranes with their bare red-topped heads roost in the ponds of the preserve. The significance of the preserve as a crane stop is highlighted by featuring them in the Cosumnes River Preserve logo and in the crane sculpture in front of the visitor center.

Cosumnes River Preserve

Cosumnes River Preserve sign next to Franklin Boulevard

Cosumnes River Preserve logo
The Cosumnes River Preserve is a valley oak and wetland preserve in California's Central Valley [1-4]. About 90% of the original grasslands and wetlands in the Central Valley have been lost by conversion mostly to agricultural land. At a preserve kiosk you will find the interesting information that there were times when one could travel by boat all the way from Sacramento to Bakersfield. Efforts are now taken to enlarge preserved areas and restore others to ensure lasting water supply, support migratory birds on the Pacific Flyway and generally benefit recreation and agriculture.

Middle Slough
Within the Cosumnes River Preserve hikers and birders can experience wetland habitat and a band of riparian oak forest turning into oak tree savanna with increasing distance from the Cosumnes river and adjacent sloughs. Boardwalks, interpretive panels, various loop trails and occasional benches invite visitors to stroll, hike and picnic at a scenic point. My favorite spot is the tree site with the majestic valley oak (marker 22 at the River Walk Trail). Paddlers will enjoy the free-flowing, forest-lined river.
Cosumnes River
As the Cosumnes River Preserve signshown in the top picture—indicates, this nature preserve is the result of a dedicated conservation partnership. Jordan Summers writes (page 90 in in [1]): “The Cosumnes River Preserve is managed by the Nature Conservancy, the U.S. Bureau of Land Management, Ducks Unlimited, the California Department of Fish and Game, the State Lands Commission, the California Department of Water Resources, Sacramento County, and private landowners.” Indeed a diverse partnership highlighting the importance and many interests in preserving wetland resources.


Getting to the Cosumnes River Preserve visitor center and trailheads

The preserve is located about twenty miles south from Sacramento. From Interstate 5 take the Twin Cities Road exit and turn left on Twin Cities Road. Continue east for about one mile, then turn right on Franklin Boulevard and go south. After passing the Cosumnes River Preserve sign continue for another mile to find parking space and the visitor center at 13501 Franklin Blvd. on the left. No fees or permits. The trails start on the left side of the visitor center. Half-way between the Cosumnes River Preserve sign and the visitor center is another parking area off Franklin Blvd. to do the Lost Slough Wetlands Walk. If your goal is the Cosumnes River Walk, you want to start at the visitor center trailhead, cross the bridge and then turn right to walk south alongside Middle Slough. This path guides you to the loops with Cosumnes River views and access on both sides of the railroad tracks.
