I cannot gush enough about the Go Ape experience. This course gets you up into the trees for a challenging obstacle course with exhilarating zip lines over the water. Some of the zip lines are over 650' in length. The obstacles are challenging enough to scare you just a little (even though you know you are securely fastened at all times), but not too challenging that our 11-year couldn't do them. The guides are excellent, and provided great instructions and safety guidelines before anyone was allowed on the course. The larger your group, the longer it will take you to complete the course. I would recommend that your group not be larger than 4 people, unless you don't mind waiting for your group to progress on through the course. Great family experience, and a great way to build confidence with kids. This review is specific to the Delaware location - I have not visited any of the other locations. Wear clothes and shoes that can get dirty!
