What's inside
“A fairly small modern urban-type bouldering gym mostly trafficked by students it seems.”
“Training equipment is limited (a couple of hangboards, pull up bar, weights).”
What climbers say again and again
“The route setting is outstanding, the equipment is all brand new and high quality.”
“Only been here twice before, but it's proven to be a nice space for both a beginner like myself and my friends that are more advanced.”
“Super friendly staff who will set you up right.”
“The air felt a bit chalky too, so it might help to wear a mask while climbing or hanging out in their upstairs lounge area.”
“The crowd is young university students mostly and they are open late with affordable pricing”
From the reviews
Fantastic; loads of engaging and inspiring boulders. Masterclass in stacking holds and blockers. Only $10 first time day pass. Love it
Conveniently located for Cal students, otherwise parking here is difficult. The gym is small but the routesetting is dense to maximize the number of routes. Everything seems to cater more towards beginner/intermediate climbers with only a few climbs in the upper rating.
Awesome local climbing gym at Berkeley. The atmosphere is great and the employees are super chill. Great route setting and cool holds. There's also a nice upstairs area with some free weights, bands, pull up bars, and hang boards where you can also sit and study. Also a deck to hang out on in the back.
A fairly small modern urban-type bouldering gym mostly trafficked by students it seems. Staff and people climbing were all really nice, and despite being a small space, I felt that the routesetting was pretty good/fun, and they have a variety of wall from slab to overhung.
