Visiting Watershed Lands

"The Mt. Tamalpais Watershed… is held in trust as a natural wildland of great biological diversity, as scenic open space and as an area for passive outdoor recreation for Marin and much of the Bay Area. Passive outdoor recreation is defined as those activities that are based on nature and that require little or no development or facilities.” -Marin Municipal Water District's Mt. Tamalpais Watershed Management Policy.
