Ring Mountain Preserve

A treasured windswept ridge atop the Tiburon Peninsula.

Rangers Recommend

  • On a clear day, enjoy stunning 360 degree views of the entire Bay Area.
  • The preserve is famous for its geology. Rocks on the slopes display mineral amphibolite, eclogite, and tiny garnet crystal. Higher elevations hold serpentine. Turtle Rock, a massive boulder, sits between the mountain’s crests.
  • Take Phyllis Ellman Loop Trail (1.76 miles) for a nature journey through oak woodland, wildflower strewn grasslands, and seasonal creeks.
  • A Miwok village site on Ring Mountain has been dated to 370 BC. Petroglyph Rock is an important archeological artifact.
  • At the end of Taylor Ridge Road, find remnants of a 1950's Cold War military installation.
  • Dogs welcome, but must be leashed at all times.

Naturalist Notes

  • The Tiburon mariposa lily, which typically blooms in May, is found nowhere else on earth.
  • Wildflowers abound in spring, including milkmaids, Fremont's camas, buttercups, and shooting stars.
  • A variety of raptors circle the mountainsides.
  • Keep an eye out for rock wrens – this is one of the few places in Marin where the birds can be seen all year.
  • Check out the iNaturalist field guide. Add your own observations.
