Russian Ridge Open Space Preserve

The preserve encompasses about 2000 acres of grasslands, ridges and hillsides. The narrow dirt trails cover mainly exposed areas so bring a hat. The area hosts a diversity of plants and birds and, in the spring, there are a variety of orange, purple and yellow wildflowers.  There are about 10 miles of flat and rolling hill multi-use trails for hiking, biking and equestrian use with views of the Pacific Ocean and San Francisco Bay on clear days. There are two main entrances and both have restrooms.


No dogs are allowed in the preserve.
