Dirtworld.com, a great mountain biking and adventure sport website, recently published an article titled "Epic Rides in teh West" where Moab's Porcupine Trail was top rated. Next to the Slickrock Trail, Porcupine is the second most popular run in the area. It is a 31 mile loop if you take the whole trail, and has some great destinations and sceninc outlooks across the way.

Trails aren't ideal now, but once the weather starts warming up, spring is a great time to get a few runs in down in Moab. Usually people bring their own bikes (if they are serious about biking), but Moab also has plenty of bike rental stores and guided trips down the most popular trails. This could be the best option for vacationers who dont want to drag their own bikes down there.
