There is so much about Mount Tamalpais—the tallest peak in the Marin coast range—that binds us.

Its natural beauty, and abundant opportunities for adventure and inspiration, bring us together. Its stories and history, intertwined with our own, make us one. Its presence, ever a comfort, is a constant held in common.

Now, we have an approach to the care and stewardship of this community treasure that is just as unifying and all-embracing: the Tamalpais Lands Collaborative (TLC).

In November 2014, the TLC launched OneTam, an initiative to raise awareness and build community support around efforts to care for the mountain’s treasured resources. Check out the new OneTam website at
