Starting from the trailhead in the wash, it's 1.5 miles to the playground. There you'll find a huge expanse of gradually sloping sandstone, with small ledges, bowls, and other fun stuff. You can head another mile south and east over this huge area of open rock. Altitude gain is 300 feet. View over the Doc's handlebars, looking south along a ramp of rock on the way to the top.
Some riders start from the parking area just beyond the railroad tracks.
From here, it's 4 miles to the real trailhead. If you have a 4-wheel drive vehicle, we suggest you skip the road. The first two miles are absolutely boring desert, then you have to hike through a mile of unrideable sand. Our description assumes you drove the wash, and are starting at the slickrock trailhead. Gary packs his bike up to the next ramp.
