Climbers cling to the carefully placed hand grips, strategizing their way up the side of the rock-like cliff. They have come to Hadley to conquer the Central Rock Gym's 16,500 square-foot climbing wall, reaching 45 feet in height. The facility features climbing walls that range from beginner to advanced levels. Experts guide novice climbers through introductory classes, including the required beginner's class, or supervise more seasoned members scaling the walls' highest heights. Memberships unlock access to all six facilities, gear for the first month, and the use of exercise equipment and weights. In addition, memberships grant access to fitness areas, yoga classes, instruction, and other benefits.
