I'm just posting another 5* review for this company! We took our 17yo son and he had a blast - he was able to to a back flip the first time out and did 3 hand offs by the end. The instructor was patient, he gave very clear instructions and he had a great sense of humor as well! The staff were also awesome and obviously very experienced.
It's super safe and lots of fun. I would recommend that you wear tight leggings of some sort because the swinging bar has texture on it and the back of my son's legs were getting a bit sore toward the end - this could have been avoided if we'd planned better.
One more thing - the trapeze is set up outside, not IN the building so if you're at this location, be sure to go around the building, to the right, not IN the building. There's also plenty of covered seating for parents and other spectators so even though it was a hot day, we were fine.
