Rattlesnake Canyon Arches
The 6.2-mile round trip Rattlesnake Canyon Arches Trail outside of Grand Junction is literally off the beaten path—it requires driving a rough-and-tumble 4X4 road or hiking a connector trail—but the views are completely worth it. The high-desert route travels through reddish-orange, Mars-esque rock formations, and arches with colorful sandstone layers.
