Earth Treks Climbing Center in Rockville is a premier indoor climbing gym offering varied climbing terrains, strength and cardio training space, yoga studio, fully-stocked gear shop, and locker rooms. The facility has one of the largest indoor climbing walls (it's 40 feet tall!) with more than 38,000 square feet of climbing. There are also shorter, less steep walls to allow new climbers and kids to climb safely. Earth Treks provides rentals for climbing shoes, harnesses, belay devices, and chalk bags. The staff also changes out the climbing routes every few weeks, so there are always new routes to try out.
