Our family with kids ranging from 9 - 14 really enjoyed the experience. 12 zip lines provide good value for the experience. It starts of easy, with shorter lines and then gets longer and faster. There are a few double lines, where you can race others in your group. Based on the size of the group it takes about 2 hours. It's a scenic area close to Lake Catherine; GPD has a hard time locating, so use directions from their website.
