8.5 miles (14km) one-way from the Cave Spring gate to Fortress Arch
Four at-large permits for the Salt/Horse Zone
There are no reliable water sources in Horse Canyon. Water is usually available at the junction of Salt Creek and Horse canyons.
From the gate at Cave Spring, hikers follow Salt Creek Canyon for 2.5 miles before reaching Horse Canyon. Horse Canyon is typically very dry, and the deep sand of the wash bottom makes for slow hiking. A four-wheel-drive road extends up the canyon as far as Fortress Arch, so hikers may see vehicles. There are several arches and numerous side canyons to explore.
