While standing in Altitude Gym, it’s easy to forget that you aren’t outside. Life-like rock walls tower over guests, brandishing footholds that climbers use to scale up to 45 feet in the air. Climbers of all skill levels put their limbs to the test with the gym’s 50 lead climbs, 50 top ropes, 1,800 square feet of bouldering space, and 17,000 square feet of climbable surfaces. In addition to open gym time, the center also hosts introductory climbing lessons led by expert instructors, 10-week adult boot camps, climbing clubs for ages 5–7, and self-defense classes for climbers who encounter territorial mountain goats.
