My husband and I did this "tree top adventure" while passing through town. We went on a Monday, at the earliest time they had available. I think that really made our experience that much better because we were the only ones there. It took us about 1.5 hours, and I can see this taking a really long time if you're behind a group or are with a big group. I felt safe the whole time, but your safety is your own responsibilty. There's a guide on the ground watching everyone but all the connections to the ziplines and ropes are do-it yourself. They give a very thorough explanation and have everyone demonstrate their understanding of the instructions before you can go up in the trees. Our guide was attentive without being overly watchful. I had a great time and the surroundings are beautiful. You do have to pay an admission into the park where this is located, but this is minimal. I recommend wearing clothes you don't mind getting dirty. My only suggestion for the company is that they have an area set up at the end where you can take photos or have an employee available to take photos, maybe a big sign that describes you accomplishment?
