Due to small amounts of sand and the way some hills work, there is a slight preference for doing this route clockwise, as shown.
There are a lot of motorbikes on these trails. Remember they probably can't hear you. They aren't too bothersome though, and the trails are in good shape.
You can either start from the main trailhead, or drive in another couple miles to the McDonald Creek trailhead. 4WD is not really necessary to go there, but it is a rough dirt road.
Starting from the main trailhead, quickly find Rabbit Valley 2
trail on the right side of the road. It starts as a flat, fast, wide singletrack goes up and down some small creeks. There are several sandy sections and dirt road crossings. At a few points, you use the dirt road for the trail, so look for signs to get you back on the trail.
Once at the McDonald Creek trailhead, follow the Kokopelli trail (dirt road) for another couple miles until you get to a huge 4-way intersection and good view of the Colorado River. This section has many intersections; keep you eye out for the carsonite posts with the blue-ish Kokopelli signs. Use the MTB Project mobile app in this section to stay on the correct path, and to avoid missing the start of the Western Rim
From the four-way intersection with the Kokopelli Trail
, follow a two-track trail with no signs in an non-obvious direction (use the MTB Project mobile app!). Follow this a few hundred yards, bearing left when another dirt road goes off the to the right.
The road soon comes to a gate and turns to singletrack. Go down a steep, very sandy hill for a short ways until you get to the rim. You now have miles of dead-level terrain on this rim with increasingly good views.
The rest of the trail is fast, smooth, and great fun. It's sometimes on slickrock, sometimes dirt, with occasional very short easy hills. Wander in and out of huge side canyons with views of the La Salle mountains, Colorado River, and farmlands below.
Climb back up to the top of the mesa where the trail turns slightly more technical and hilly, but still only intermediate difficulty. Remember to turn around and look at the cool terrain that you rode earlier.
The trail dead ends on a dirt road. Turn right to get back to the Kokopelli Trail
. Follow it back to the big 4-way intersection with the start of the Western Rim
trail. From there, veer left on Rabbit Valley 2
trail, and enjoy fast swoops through the valley back to your car.
