The Sibley Volcanic Trail is no joke: the trail explores what was once one of the largest volcanos in the Bay Area.

The Sibley Volcanic Trail is a 3.8 mile loop that is great for all skill levels. The trail is best used from June - December, and is shared by kids, trail runners, mountain bikers, and hikers. Watch for wildlife and wildflowers. 

There is little to no shade, so wear sunscreen and bring sun protection. Dogs are allowed off leash here.
