Crate challenge is a high activity with the emphasis on teamwork. Four children, each wearing a harness with safety rope attached are given the challenge of building a crate tower together. For this session we use an auto-belay system which will ensure anyone falling from the tower is gently lowered to the ground at a very safe and steady pace. The children need to work as a team, climbing up the crate tower as they build it. The rest of the group offer assistance in different ways, in particular by passing crates up to those building the tower as the tower gets higher.
