To get to the trailhead, you must first drive to the Dinosaur Quarry Visitor Center in Dinosaur National Monument, which is east of Vernal. Use a Utah Road map for the drive. After obtaining updated information from the visitor center, drive east on the Blue Mountain Road and turn left at sign for the Split Mountain Campground. The Desert Voices Nature Trail starts across the street from the campground. Park here.
The Desert Voices Route is marked with the blue line.
A topo map is needed to follow this route. There is no trail after leaving the Desert Voices Nature Trail at Cottonwood Wash. From the trailhead, follow either loop of the Desert Voices Nature Trail (the northern branch is shorter). Instead of making the loop, head west up Cottonwood Wash when the loop trail begins to backtrack. Follow Cottonwood Wash until it turns right (north) and cuts into Split Mountain. This is about 2.4 miles fom the trailhead. Hike up to the ridge to the west of Cottonwood Wash. If you have a GPS, this is at N 40*26'59.482" and W 109*16'57.362". Follow the ridge-line north until you reach the wide main west-east ridge of Split Mountain. This is at N 40*28'39.455" and W 109*16'16.629". Follow the main ridge east to the summit. The summit is 6.4 miles from the trailhead. Enjoy one of the most spectacular views anywhere. The Green River is 2500 feet below and to the south. Much of the drop is dead vertical.

A good pair of boots and all the normal hiking gear is needed.
"No, I will not drive across Colorado to visit the highpoint of Kansas. What do you think I am, crazy?"
