In belay-certification classes, held three times each week at The Gravity Vault's Chatham and Upper Saddle River locations, students learn the intricacies of belaying—the art of securing the rope while their partner scales the wall. After reviewing the basics of the sport, climbers receive hands-on training on equipment, rope and harness safety, and verbal commands in both English and Bald Eagle. All rental equipment is included.

Private climbing lessons pair students with an instructor, who guides the group as they tackle a variety of routes around the facility, operating the ropes for each climber and doling out advice from below. The leaders of six-week kids' classes design fun training regimens that foster physical fitness and critical thinking while teaching youngsters basic techniques. Grouped by age, sessions cover everything from tying knots to traversing boulders before they transform into waterfalls. Though harnesses are provided, each participant should wear sneakers and comfortable clothing and bring their own water and snacks.
