One of several old warehouses in Norcal that have been converted into a climbing gym (one has recently sprung up in downtown LA called LA Boulders). For climbing it's pretty cool, there is bouldering upstairs as well. For new climbers they have hourly lessons or you can skip the lessons and test any time, but you have to pass the ropes test to climb. I generally come here for the fitness area, and the breakdown on these gyms is about 70% dedicated to climbing and 30% to fitness. This is the smallest gym space of all locations and it's one of the busiest locations, so I don't really enjoy that cramming part of it but it's still a good place to work out.
