Cottonwood Canyon Road — Grand Staircase-Escalante Badlands Spine via Grosvenor Arch

Cottonwood Canyon Road runs 46 miles between US-89 near Paria and UT-12 near Cannonville, cutting straight through the geological heart of Grand Staircase-Escalante National Monument. The Cockscomb — a razor-sharp monocline of red and tan sandstone — runs parallel for much of the southern stretch, and the road hugs its base like a scar. About 10 miles in from the southern end, a short spur dead-ends at Grosvenor Arch, a rare double-arch formation that most people drive right past on US-89 without knowing exists. Cottonwood Wash crossings become the deciding factor after any rain — the clay-heavy bentonite surfaces turn to grease that will high-center a pickup before you realize you’re sliding.

This is a moderate-to-difficult route depending entirely on recent weather — Bureau of Land Management road conditions should be checked before you leave pavement. A high-clearance 4WD is the minimum; aired-down tires help significantly. The road is usually passable by stock trucks in dry conditions but closes without warning when wet. No fuel between US-89 and Cannonville — fill up in Kanab or Escalante. Water is scarce; carry your own. Dispersed camping is allowed throughout the monument. Best season is April through June and September through November. This road rewards patience with isolation, geology, and access to canyon country that most people only see from the highway.
