This trail is great. It is not as rocky as other Phoenix area trails( ie: Trail 100, National, Estrella Mtn Park). Twisty singletrack on rolling contour. The surface consists of small pebbles which make a nice ripping sound as you careen through the turns. These are one way loops, there are three total. The sport, technical, and long loop. Distances are ~ 3 , 3 , 6.5. Enjoy.
