My two boys, ages 9 and 11, had a great time on the obstacle course. Participants need to click the safety cable in and out of every section (every 1-3 minutes) which is time limiting and at times a little frustrating. They got very good at it, but I saw other kids struggling with that step. It is harder for kids than adults because of their height, but they can step up onto a little ledge at each pole. Otherwise they had a blast and were able to do all 4 levels of the course. They lasted about 2 hr 45 minutes. The central area to watch/wait is very comfortable offering shade and nice chairs to relax in. Way better than similar venues! The kids were able to come down for water and snack breaks. Just bring your own food as there are not concessions available. We purchased the ninja warrior course add-on which was not necessary and I donāt recommend. The boys were tired after playing on the obstacle course and the ninja section was pretty lame compared with other ninja places they have been.
