Lucas Valley Preserve

An expansive south-facing slope rising above a historic Marin valley.

Rangers Recommend

  • Big Rock Trail, part of the Bay Area Ridge Trail, begins at the crest of Lucas Valley Road and eases its way up to Big Rock Ridge Fire Road.
  • See spectacular views from Mount Burdell to the Golden Gate. At 1895 feet the summit is the second highest in Marin, surpassed only by Mount Tam.
  • Incredibly steep Luiz Fire Road offers a strenuous alternate route between the valley floor and the ridge.
  • Film director George Lucas donated 800 acres to help create the 1271-acre preserve. The name Lucas Valley dates back to an early settler–John Lucas, who lived here in the mid-1800s on a 7600-acre ranch.
  • Dogs are welcome. Dogs must be leashed on trail, and under voice command on fire roads, with leash readily available.

Naturalist Notes

  • Look up while walking along the ridge; golden eagles ride the updrafts.
  • Raptors including red-tailed hawks and northern harriers hunt along the ridge. Carrion-feeding turkey vultures also thrive here.
  • Poppies, monkeyflower, and babystars bloom in spring, especially after a rainy winter.
  • Sparse roads and trails make this an ideal place for shy wildlife that prefer solitude and wilderness, including bobcats.
  • Check out the iNaturalist field guide. Add your own observations.
