Horse Hill Preserve

The herd of horses grazing peacefully on Horse Hill is a beloved Mill Valley landmark.

Rangers Recommend

  • Enjoy observing the fourteen horses that live on Horse Hill, which is leased by the Alto Bowl Horseowners Association.
  • Climb to the top of Horse Hill Fire Road. On a clear day you can see views of Mount Tam, the Tiburon Peninsula, and San Francisco Bay.
  • In winter, seasonal springs run on the south slope.
  • The Hill is a favorite field trip for local schools, introducing kids to Marin's agricultural traditions.
  • Travel through to the Alto Bowl Preserve and points beyond.
  • Dogs are welcome. Dogs must be leashed on trail, and under voice command on fire roads, with leash readily available.

Naturalist Notes

  • In spring, look for lupine, blue-eyed grass, and Douglas iris wildflowers.
  • Circling overhead are raptors, including American kestrel, red-tailed hawk, and northern harrier, who feed on a healthy population of voles.
