French Ranch Preserve

A majestic south-facing slope rising above western San Geronimo Valley.

Rangers Recommend

  • Together with Gary Giacomini and Roy’s Redwoods, French Ranch's 403 acres constitute a major portion of the Lagunitas Creek watershed.
  • Take French Ranch Fire Road up to a ridge overlooking the valley.
  • At the western end of the preserve a steep slope holds significant areas of exposed serpentine soil.
  • Dogs are welcome. Dogs must be leashed on trail, and under voice command on fire roads, with leash readily available.

Naturalist Notes

  • The Lagunitas Creek watershed provides important habitat for endangered coho salmon.
  • Douglas-fir, redwood, oak, and tanoak rise from the deep, forested canyon.
  • Look for rare plants like serpentine reedgrass, Tiburon buckwheat, and Tamalpais lessingia.
  • Listen for nuthatch chatter, and the drum of woodpeckers.
  • Check out the iNaturalist field guide. Add your own observations.
