Beginners and expierienced riders will have a good ride. Any of them. There are no spots were you should need to get off your bike. Also you can keep riding forever. It is really rocky.
Tires find it hard to grip on a lot of it.
It is a nice ride for any skill level. Always finding new trails. Thrills after thrills. If you are from out of town, be sure to do the loop a few times. Be careful for for snakes and cactus.
