My teenage son and I loved this course! The course is designed to have up to four different levels for the adults and there is a separate course for younger children. You can leave the course at the end of each level if it becomes too challenging. In addition, the staff are there to ensure your safety and can help you off the course at any of the obstacles if necessary. The levels are setup in increasingly level of difficulty. The black course at the end takes quite a bit of upper body strength. There is a great diversity in the obstacles and the transitions are nicely mixed up. However much of the course that you complete, you will feel that you have pushed yourself and overcome some challenges. If you bring gloves (recommended - they also rent them theree), I recommend that they be ones that are tight fitting so that it is easier to work the equipment (mor like glove liners if you have them). Safety is a big concern since you get quite high in the trees. They have a great system of having a red line throughout the course that you are tied into. The biggest challenge for me was the rings at the end of the black as I was quite tired by then and it is a challenging obstacle. There are a few ladders that you need to climb which wear you out because you are constantly holding onto the ladder with one arm while changing your connection. This is a very reasonably priced activity which gives everyone a great experience. Even the people who just watch from the ground (my wife) had a good time. We plan to do it again when we are in the Flagstaff area and it was the highlight of our weeklong trip to the area.
