Habitats of Morro manzanitas are sand dune areas and maritime chaparral, which are found south of Morro Bay, for example, in Montaña de Oro State Park and the Elfin Forest Preserve in Los Osos, where they occur along with ancient pygmy coastal live oaks (Quercus agrifolia) and wedgeleaf ceanothus (Ceanothus cuneatus) . A Montaña de Oro State Park interpretative board gives the following information:
Morro manzanita is a unique shrub of limited distribution occurring primarily on ancient sand dunes only in the South Bay region. This coastal species is associated with maritime chaparral, coast live oak, and dune scrub plant communities. It provides an excellent wildlife habitat for resident and migratory species.
Guided walks are offered occasionally through the Elfin Forest nature preserve. The nearby State Park has various trailheads from where you can start a self-guided tour by staying on the marked trails through the sand dunes.
