A backcountry road leads to this stunning gorge which is part of the Oregon Desert Trail. The gulch itself stretches between Three Fingers Rock and Owyhee River. If you are out of water, follow the canyon to the west to get to the river. The Oregon Desert Trail however will take you into the gorge which is overgrown in places. Look to your left and right to see some ruins of old corrals.

The Three Forks Hot Springs are located on the west side of the Owyhee River. If you have to ford the river to get to this unique spot, the best place is just on the opposite side of the hot springs. The water might go up to your chest (I am 5‘3“), but even in spring time, the current is okay if you ford carefully.

A rough road leads to the trailhead of Coffeepot Crater, but if you drive carefully, you can even make it without high-clearance. If you are not convinced, park your car further up and walk down the rocky road. From the trailhead, you can explore around and even in the remote Coffeepot Crater and its nearby volcanic vents.
