We did a half day on one of the ropes courses for my son's 11th birthday (with 8 other boys), and it was a blast. Despite being 30 feet off the ground, the kids (and adults) picked it up right away. At the end, we also did a "rope swing" which is absolutely and adrenaline rush. You step off a 30-foot platform and swing up into the tree in your harness. The leaders of our group were friendly, trained us well, and kept everyone very safe. I highly recommend Summit Vision!
