It was me (a somewhat out-of-shape almost 50 yr old woman) and my two teenagers. We've been ziplining before, but this is different and far more challenging. Lots of ladders to climb. But none of the obstacles was too much for me and we all had a fantastic time. If you take kids under 16 you must have an adult to kid ratio of one adult for every two kids, so don't plan on a big birthday party without additional help. You are responsible, after an exhaustive training session, for attaching yourself properly; there are no guides up on the trees with you. The course seems very well maintained and the staff are great. Lots of fun!
