Ring Mountain Preserve
365 Taylor Rd
Tiburon, CA 94920
Natural Area: Birding, Hike, Picnic, Walk
The unique geology and microclimate of this location provide a home for a number of rare plants. The soils on the ridge are heavily laced with the mineral serpentine. Soils derived from this mineral are toxic to most plants, but a number of species have evolved mechanisms to survive on serpentine. As a result, where serpentine soils are found, there are usually isolated populations of rare plants. There are several access points to the trails on this preserve, but the best approach is to start at the trailhead on Paradise Drive and follow the Phyllis Ellman Loop Trail to the top. During spring, the wildflowers along the way can be breathtaking, as are the views of San Francisco and the entire Bay Area at your feet.
