Diamond Valley Loop: Lone Pine & Cottonwood UTV Guide
The Diamond Valley–Lone Pine–Cottonwood loop is an easy, scenic ride on dirt roads in the foothills north of St. George. You’ll see old volcanic cinder cones, a lone pine standing in a pale canyon and big views down to Sand Hollow and Sand Mountain. It’s a great pick for families and first-timers. Here’s how to ride it.

The route
The loop links Diamond Valley, Lone Pine Canyon and the Cottonwood Road area on wide dirt roads. You’ll use paved roads to reach the start, and part of the ride passes through the Diamond Valley neighborhood, so slow down and keep the noise low near homes. The roads can be washboarded in spots and get muddy after rain.
What you’ll see
- Volcanic country: on the Diamond Valley side, cinder cones and a dormant volcano with a crater, with views reaching far to the west.
- Lone Pine Canyon: a single tall pine standing against a pale, almost white canyon. It’s a great photo when the light is right.
- Cottonwood side: views down to Sand Hollow Reservoir, Sand Mountain and the country to the east.
- Pine Valley Mountains: the 10,000-foot range rises right behind the loop.
Tips for a great ride
- Respect the neighborhood. Go slow and quiet through Diamond Valley.
- Close gates behind you on ranch roads.
- Skip it after heavy rain; the dirt roads turn slick.
- Bring a jacket in winter; it’s higher and cooler than St. George.
