Greylock has two outstanding climbing walls on its facility. One, for our youngest boys, is two-sided and is 40 feet in height. Our more advanced wall is four-sided and 70 feet in height. Each side of each wall has a different pattern that is designed to be sequential in difficulty so boys learn and progress. All boys who participate in this program are properly harnessed and all instructors are certified in safety and skill procedures. The climbing wall is among the camp’s most popular adventure activities.
