Our church youth group went and we had a blast. If you can't do the zip line you can hike along the course fairly easily. They were really great about helping the littler zip liners! The kids would love to go back! They give a price break for a group and an adult must accompany a child.
My 10 year old went on a field trip here and loved it. They have an extensive area of ziplines in a beautiful natural setting near Saurtown Mt. and Hanging Rock state park. The ziplines offer a great adventure and a unique experience for older school age children and they are careful about saftey with helmets required for all participants. I reccommend this as a great outdoor activity especially in the fall when the leaves are changing.
