During a birthday party, all belaying  is in the hands of our staff, allowing parents to sit back, take pictures, and cheer on your little climbers. A birthday party package will include one staff belayer for every five children. With additional climbers, in increments of five, we will include another staff belayer. For example, if you have seven birthday climbers, we will provide two staff belayers. With twelve climbers, there will be three staff belayers, and so on. Optional equipment, such as shoes, are available for an additional cost.
