Known for its harsh desert landscape and spectacular rock formations, Utah’s Arches National Park is one of the most iconic parks in the United States. Massive sandstone arches carved by a millennia of erosion are scattered throughout the park, giving the terrain an otherworldly feel. The 7 mile long Devils Garden trail is the best way to see Arches; it runs the length of the park and connects to side trails leading to Delicate Arch and The Windows. Due to its small size, Arches is not a great spot for backpackers. Backcountry permits are required, and cannot be reserved in advance.
