Blithedale Summit Preserve
Glen Fire Rd
Larkspur, CA 94939
Nature Preserve: Bike, Birding, Hike, Horse, Walk
This preserve is the largest link (639 acres) in a chain of preserves that follow the “Northridge” of Mount Tamalpais as it sweeps down between the communities of Mill Valley and Corte Madera. The trails and roads in this area pass through a variety of habitats, including deep forests and dense chaparral. The fire roads along the ridges are generally steep and rocky, but there are plenty of routes that take you through quiet redwood groves among huckleberries and sword ferns. Pileated woodpeckers and the endangered northern spotted owl nest here. The woodpeckers chip away at fallen trees looking for carpenter ants by day, while the owls swoop down on dusky-footed woodrats at night. In spring, listen for the endlessly melodic song of the winter wren in the deeper canyons. These cool canyons support a variety of different lilies in early spring, including fetid adder’s tongue and two species of trillium. In the chaparral, look for the uncommon tree poppy among the manzanita and ceanothus.
To protect sensitive wildlife species, some trails in Blithedale Summit Preserve are subject to seasonal night closures. Please observe trail closure signs.
