Dogpatch Boulders, the newest climbing gym in San Francisco, is the largest bouldering gym in the country. The gym combines Touchstone's history and commitment to the climbing community with state of the art flooring and wall design to bring you the best that the industry has to offer. With 14,000 sq ft of climbing, we were able to design a gym that has something for everyone. And for the little ones in your life, we are excited to offer a kids climbing area complete with a castle and slide.
