Round Mountain rises in Castle Valley to the east of Moab, Utah. Castle Valley is basically a trench roughly 7 miles long by 3 miles wide. The southern end of the valley is blocked by the 12000 ft peaks of the La Sal Mountain range. To the east and west, continuous lines of red colored cliffs form the walls of the trench. To the north, Castle Valley drains into Colorado River. Round Mountain rises very abruptly 1000 vertical feet above the floor of the valley.

Round Mountain does not have a trail but you can find your own way up the gullies between its cliffs. Maps show a 4 wheel drive road that leaves Castle Valley Road and makes a loop around Round Mountain. This site mentions an approach via the 4 wheel drive road and the southern slopes of Round Mountain. I, instead, decided to park on Castle Valley Road and hike up the eastern slopes of Round Mountain. This required a one mile hike on the valley floor up and down a couple of small dry washes and then bushwhacking up a steep rock filled gully.

Getting There

From the junction of Routes 191 and 128 to the north of Moab, drive 15.5 miles east on Route 128 and turn south onto Castle Valley Road. After another 7 miles on Castle Valley Road, you will find the Round Mountain dirt road. This road was actually not signed and I saw other dirt roads in the area so it became somewhat confusing. That was why I decided to just hike the valley floor to reach the base of the eastern slopes of Round Mountain.

Looking down the gully I climbed. I then had to descend a short distance down the west slopes to go under a cliff, then followed the easy spine of the mountain north to reach its summit.
