Spanning 4,000 square feet, the climbing surfaces at First Avenue Rocks mimic the natural textures of the abundant local sandstone boulder terrain. One hundred varied climbing routes up to 17 feet high greet climbers who choose to ascend by bouldering without ropes on angled walls and roofs dotted with challenging foot-and handholds or on the facility’s ropes courses. For safety, the facility positions its vertical terrain above the floor’s 10-inch-deep Asana pads for safe landings in the event of missed holds or misguided urges to fly. Instructors are available to prep students of all ages and ability levels to tackle the gym's terrain, teaching three stages of introductory climbing courses and two advanced lead-climbing courses. When not on the rocks, guests can hone muscle cooperation through onsite fitness programs in weight training, yoga, CrossFit, and climbing-specific training. Outdoor excursions are also available with the gym's guides, certified by the American Mountain Guides Association, in top rope, sport climbing, and bouldering.
