We were there in early July of 2012. Honestly, I was a bit apprehensive after reading some of the negative reviews, particularly regarding safety as our group that went on the Adventure Course included our teenagers. First, there are no helmets. I hate to break it to you, but if you were to have a fall from one of those zips/obstacles, a silly little helmet isn't going to do much for you anyway. Which brings us to the condition of the equipment. I'm no expert in zip lining technology, but the equipment looked to be in good shape to me. I saw no fraying on either the harnesses nor the cables. The guides made sure the fit was snug on all of us before we ventured out. At no time during the Adventure Course did I feel remotely endangered by any type of equipment failure. Please bear in mind, during the course, your safety is largely in your own hands and it is impossible for the guides to watch anyone every single second. If you want your hand held in the name of safety, go to Cedar Point instead. Overall, it was slightly strenuous for me (43 year old, soft in the middle, smoker), but easy for the teens. I would do it again. A couple of negatives: included with the Groupon was Frisbee Golf. We came out of the golf course covered with tics. Also, we stayed at Blackjack Crossing which are the cabins affiliated with this park (about 2 miles away). They were ok, but I'll bet we can find better cabins down there. Finally, the water slide was closed after being damaged in a storm, but we understand that Hocking Peaks doesn't control the weather. We thought the guides were friendly, the day was fun, and we would return.
