UB is a "bouldering" gym- this means there are no ropes or harnesses. Instead there are large foam mats to fall on and the walls are short. Your feet will never be more than ~6-8ft off the ground! It's very safe and tons of fun!
It's bouldering, so the top of the wall is at most ~12 ft off the ground. There is padding on the ground that you can fall on, but otherwise you don't use any ropes. Unless you're diving headfirst into the ground, it's perfectly safe.
