"Climb Away" Come check out our wall! Nashoba North has a 35-foot climbing wall. Each of the six sides offer varying levels of difficulty. Our qualified instructors can work with all levels of climbers, from beginners to more advanced. A critical part of their instruction is ensuring campers learn all the necessary safety techniques including the proper use of equipment, how to tie in, climbing commands, and belaying. Campers can participate in guided climbing trips throughout New Hampshire and Maine.
