Trail surface of fine volcanic fine gravel is rough but suitable for 3 wheel cycles. Rode counterclockwise by fitness stations at regular intervals. Mostly shade less, with great view of the highest point in Arizona, (Hopi: Aaloosaktukwi) at 12,637 feet. The southwest section of the trail has a steep curved grade in and out of a ravine that does not provide enough traction for a 3 wheel cycle. Fish-tailed on way down and had to wheelchair on the way up. It can be by-passed, where the trail splits, N35.22092 W111.63465 by going east up to the Arizona Trail/ Service Road, then to the park entrance. Noel Keller 23 Jun 2011
