Split Rock

Split Rock is a fun little crag in a spectacular setting. Flawless, sunny Bay Area weather with a sea breeze and wonderful views of San Francisco make for a very pleasant place to spend a half day and climb. The rock quality is good, but the routes are very short. Split Rock is really a large boulder, with many climbers choosing to solo the moderate face climbs as a warm-up before heading to nearby Turtle Rock for high-quality bouldering. There are no bolts at Split Rock; top rope anchors require traditional climbing gear. Because of this and the fact that some of the routes will also accept gear, it can be a fun place to practice placements for a beginning trad climber. Most of the climbs are on the north face of the rock and range from 5.6 to 5.10.

Ring Mountain Open Space Preserve occupies prime real estate in Tiburon, protected from development by The Nature Conservancy and deeded to the Marin County Open Space District in 1995. It is home to several unique flora including the endemic Tiburon mariposa lily, which grows in the serpentine soils found at Ring Mountain that are toxic to many plants.
