We had a great time here. The different levels go by age. I had a 12, 13, and 14 year old. My 12/13 year Olds could go up to the blue level, and my 14 year old could do up to the single diamond level. Then, they can do all levels below that as well. It was a little chilly still, and the leaves have not come back yet, so if it's raining, I wouldn't book yet. But they had excellent staff who did a fun and thorough job at training them to do the course. For safety, they are always connected to the lines on the tree tops. So even if they slipped, the special designed ropes will never both unlock at the same time, which put me at ease because my kids are accident prone, lol. There is a little snack shop with drinks and candy/nuts. There is plenty of seating in the center or benches along the paths if you want to walk on the ground under them. They do not charge for the spectators on the ground. The price of the ticket gives them 3 hours, and once they've gone once they can test out of the training for the next visit. It took my kids about 45 minutes on their hardest course the first time, but after that, they were running through them. It does require some upper/lower body strength. This was a fun experience that we will definitely return.
