Slippery When Wet

Slippery When Wet is an advanced technical singletrack loop in the McCoy Flat trail system west of Vernal. The shortest route is just under 6 miles, but the trail can be incorporated into longer rides by adding Retail Sale and Fire Sale or More Hoes .

The McCoy Flat trail system is managed by the BLM. Although there's no water at the trailhead, there's a toilet, a large fenced parking lot, a shaded picnic area, and well-developed trail signage.

Exit from the parking area westbound. Trail maps are found only at the trailhead, but there are plenty of marking signs.
Trails exit the parking area on the east and the west. The Slippery When Wet ride starts on the west side -- important if you don't want to be immediately lost. Consult the trail map and follow the signs.
Absolute elevation change is about 300 feet, starting at 5300. Up-and-down riding brings total climbing to 700. Although considered an expert-level mountain biking trail, intermediates can ride Slippery When Wet with a few short hikes past tricky sections.

The ride starts by crossing the McCoy Flat road from the parking area. Follow the trail signs and veer to the right to the combined Got Milk and Retail Sale trails.

Options: To do a longer ride, head right instead. Follow Retail Sale west. Do Fire Sale and continue on Retail Sale to the Slippery When Wet fork. Or take Got Milk to More Hoes , and do More Hoes before following Retail Sale to the Slippery When Wet loop.

Shortly after branching off Retail Sale, the loop splits. Keep right. This is a one-way loop. The trail will climb into an area of sandstone and mudstone. There are a couple of short technical areas.
There are views in every direction as the trail tracks along the edge of a sharp little hill. At one viewpoint, check out the cool kokopelli.

For a longer ride: When you get back to Retail Sale, flip the bike around. Ride the last 5 miles of Retail Sale trail back to the trailhead.
