Mount Tamalpais State Park in Marin County has some of the best views of the San Francisco Bay Area I have ever seen and a lot of them are right from the seat of your car. Mt Tam is the birthplace of mountain biking with many steep trails for biking or hiking all over the mountain. Local climbers know Mt Tam as a good place to find some easy to moderate top ropes on fairly solid volcanic stone with good cracks, pockets and jugs.

There has also been a slow development of bouldering going on but never more than some spread out problems of varied styles. Now thanks to luck and some inspired locals (Kenny Ariza and Eliot Carlsen) who explored all over the mountain in the last few years in search of new rock it also has a fair share of quality, concentrated bouldering areas. The mountain now sports about 100 problems with legit access on well maintained park trails.

-Bay View Boulder (on right below small turnout with big view) + East Bloc/ATF (on left in trees on hill)
[about 0.9 miles east of Rock Springs on East Ridgecrest]

-Lakeview Boulders [off Lakeview Trail west of the East Peak on East Ridgecrest]

  1. Thanks so much for the beta! These areas are fantastic. However, there is also some great potential on the southeast side of the mountain, in the watersheds.

  2. glad you like it! im very interested in any new stuff up there. we did do a few problems about a half mile before bootjack picnic area on the southeast side. there are some above and below the road next to a creek? my problem intuition is the best one there, it is in bay area bouldering. could that be some of the stuff youre thinking of? or is there more!!?? im sure there is - if you have more info please let me know..

  3. If you follow the bootjack trail both above and below the parking lot, you'll encounter several boulders, one right before Van something meadow, and one or two in the surrounding woods. There is also that big overhanging cliff below Intuition in the creek, although you probably already know about that. There are three or four rocks in the cascade area with a couple really fun problems.
