Flag Hill East Bay Parks: Sunol Regional Wilderness, Sunol, CA

A moderately strenuous hike will take you to the top of Flag Hill, which is composed of layers of fossil-rich sandstone formed some 13 million years ago. You’ll enjoy great views and good opportunities to watch birds and other wildlife. Ambitious hikers may take an optional detour to Indian Joe Cave Rocks.
