The popular activity is rock climbing and rappelling. You will need to register and get permission from the Ranger. There are fire rings with grates in the campsite. And wood is available, although you may have to search a little ways from the campsite. This is a real good place to do the mapping and hiking requirements for Second Class.
Plant identification is great here too.
There is a wide variety. And there is a nature trail with plants identified. Some animals can be seen and a patient Scout that is observant can also complete the animal identification for Second Class. Your Scouts can also make a good variety of pioneering camp gadgets. Plenty of wood is available for this activity.
