Warner Valley Road gives you a true taste of Southern Utah’s desert riding: quiet, wide-open, and wonderfully remote. The surface is mostly packed dirt with some loose or sandy stretches, so it rides best on wider tires. Traffic is minimal, but shade is almost nonexistent, and the heat can build quickly, so start early and carry more water than you think you’ll need. It’s a beautiful connector with views of red cliffs and open valleys.

The mountain gets its color from Navajo Sandstone, which is the same type of rock found in nearby Zion National Park. Over time, wind and water have shaped this sandstone into beautiful cliffs, canyons, and unique rock formations.
