We are the nonprofit partner of Mt. Tamalpais State Park. We lead informative hikes, answer questions and sell things at the visitor’s center, staff the “Gravity Car Barn,” and generally have a good time.
You are also more than welcome to join us as a volunteer in this adventure!
We have no paid staff — we are a 501c3 (Tax ID = 94-3027663).
