No, I’m no rock climber and didn’t know abou the Volcanic Rock Gym near Punahou and in Kailua. The smaller Kailua location is all about climbing. Featuring walls of varying heights and angles, this smallish space is maximized with challenges, and the climbers there are maxed out themselves. Every regular that came by was fit and well muscled – backs, legs, arms, you name it. So obviously if you want to build up your body, climbing at Volcanic Rock Gym is what you need to do.
