The route as described begins with a loop up part of the Green Valley racecourse and descending on the longtime St. George favorite, the Barrel Trail, so named for the many barrel cactus that line it. Most of the climb is relatively non-technical and of moderate grade, making it a fairly easy way to gain some elevation for the return trip. Once on top, there is a large open rock area which is fun to ride, but will require a sharp eye for cairns in some places to stay on the route. When the loop turns back down, that's where the fun (or mayhem) begins. You'll encounter all manner of stunts, some natural, incorporating the many rocks along the way, and some man-made, including ramps onto or off of rocks. There are also a few gap jumps, some times long enough to require serious speed. There are ride arounds (or hike arounds) for all the most challenging features, so a solid intermediate and a pro freerider can hit this one together and still have a great time.

The second loop is on the Zen Trail, which was cut much later than the Barrel Trail, and makes maximum use of the more frequent rock features on its part of the great escarpment. The climb for this one is longer and more taxing, but the more continuous natural technical features make it worth the effort. If you think you may only be up for one loop and you prefer natural features, then skip the Barrel Trail and just do Zen. If you're not sure, do Zen first and then go to Barrel. The upper part of Zen is an absolute rock crawler's delight, with all manner of rock moves including wide open and narrow, step ups, rollers, drops, real thread-the-needle grooves, and even a low overhang which requires the rider to really duck to clear.

These trails are all completely exposed to the harsh desert sun. The good news is that they're generally ridable year round, but if riding in the summer months, start early to beat the heat and always bring plenty of water. Bring your camera as well, as there are lots of great shots both of the mountain and desert backdrops, as well as action shots of the many features.
