The Rock Wall Climbing Gym welcomes adventurers of all ages and experience levels to scale indoor rock-climbing walls during drop-in climb sessions. Visitors strap into provided harnesses to scale the main floor’s top-rope, lead-climbing, and bouldering walls as well as more than 30 routes on lead walls while free from outdoor dangers such as feral park rangers. Walls are positioned at multiple angles, ranging from flat to 45-degree overhands and roofs, and for an added challenge, climbers can eschew the rope to scramble across cavern roofs and break free from gravity’s overbearing hugs in the bouldering area. Knowledgeable staff members hold the ropes for solo climbers, who need no prior experience, and pass on their knowledge to other adults in briefing sessions for family climbs. Parents can climb with and belay their offspring under the guidance of trained instructors, who bestow tips for various gym routes such as which ones pass over secret laboratories. The Rock Wall changes its routes constantly to provide new experiences, and preps ascending enthusiasts with beginner through advanced climbing classes.
