Groups of 6 or more participants require a 2-week advance booking and a credit card # to schedule. Group fees include harness rental, belay instruction, 3 hours of climbing, and use of the party room. Participants 15 years of age or over are required to belay for the group.  Climbnasium does NOT provide staff to belay for groups. When your group arrives an instructor will teach the group how to properly wear the harness, tie in as climbers, and proper belay techniques. For groups under the age of 15, adults must accompany the group to perform the belaying for the climbers. We recommend one adult belayer to every 4 participants. Please call to check availability of dates and to schedule 717-795-9580.  Groups have one week prior to their scheduled date to cancel or a $50 fee will be applied.
