Druid Arch is an iconic 150-foot tall Cedar Mesa Sandstone arch located within the Needles District of Canyonlands National Park, in San Juan County, Utah. It is situated at the head of Elephant Canyon, and precipitation runoff from Druid Arch drains north into the nearby Colorado River via Elephant Canyon. Druid Arch is one of the most popular hiking destinations in the Needles district. A 5.4 mile hike to Druid Arch starts at the Elephant Hill Trailhead, and the final quarter-mile is steep with some scrambling and one ladder. The name comes from its resemblance to the Stonehenge monument in England, which is believed to be a Druid temple. This feature's name was officially adopted in 1963 by the U.S. Board on Geographic Names.
