All your safety and harness equipment is provided by Aventura Parks. We'd strongly suggest bringing a large water bottle with you. There are refill stations of fresh water located around the course but no cups. You may also want to throw in a few energy bar/snacks in your pocket, 2.5 hours around the course can be hungry work! There are lockers on-site to leave your valuables, you won't have the option of carrying a bag around with you.
