Camino Alto Preserve

A Mill Valley neighborhood preserve in the foothills of Mount Tam

Rangers Recommend

  • The well-forested, west facing slope provides shady access to the ridge.
  • The preserve's fire roads are popular with hikers, bicyclists, and equestrians, offering relatively level routes along a ridge with views of San Francisco and Mount Tam.
  • Middle Summit Fire Road rises steeply in the north of the preserve, connecting with Blithedale Summit Preserve and points beyond.
  • Stop to enjoy the view of horses grazing on nearby Horse Hill.
  • Dogs are welcome. Must be leashed on trail, and under voice command on fire roads, with leash readily available.

Naturalist Notes

  • The preserve's 170 acres hold a variety of habitats, including grasslands, bay/oak woodlands, and stands of redwood and Douglas fir. Look for coast live oaks growing close to roads and trails.
  • Rockrose blooms bright pink in early summer.
  • To protect sensitive wildlife species, some areas of Camino Alto Preserve are subject to seasonal night closures. Observe road and trail closure signs.
