Druid Arch, natural arch in The Needles, Canyonlands National Park, United States

Druid Arch is a 150-foot-tall eroded fin of Cedar Mesa Sandstone at the head of Elephant Canyon in the Needles District of Canyonlands National Park. Its two keyhole openings measure 85 feet high and 20 feet wide, and the top of the formation rises 450 feet above the canyon floor.

Druid Arch is an eroded fin of Cedar Mesa Sandstone, the remains of coastal sand dunes deposited about 245 to 286 million years ago during the early Permian period. The U.S. Board on Geographic Names officially adopted the name in 1963, after its resemblance to Stonehenge.

The name Druid Arch was officially adopted in 1963 by the U.S. Board on Geographic Names, chosen because the formation resembles Stonehenge in England, long believed to be a Druid temple. Visitors today reach the arch on a 5.4-mile hike from the Elephant Hill Trailhead, the last quarter-mile steep with scrambling and a ladder.

This hike is strenuous and requires good fitness and sturdy footwear for steep climbs and loose ground. Bring plenty of water and start early or late in the day to avoid intense midday heat in the canyon.
