Closed-toe shoes are an absolute must for all activities at Treehouse World. Athletic sneakers are recommended. Absolutely no flip flops, sandals, slip on shoes, high heel, or open-toed shoes are permitted on adventure activities. We suggest wearing clothing that is comfortable to allow freedom of motion. Additionally, please wear clothing that is comfortable and modest for wearing a typical rock climbing harness, if you intend to participate in those activities. Lastly, Treehouse World is "in the woods," so you might not want to wear fine clothing that can't get a bit dirty.
