Horseshoe Mesa
The Grandview Trail descends roughly 2,500 feet over 3 miles from Grandview Point to Horseshoe Mesa, a striking mining-era landform jutting into the inner canyon about 12 miles east of Grand Canyon Village. Built by copper miners in 1893, the trail is steep, narrow, and famously rugged. Cobbled sections, wood cribbing pinned to the cliffside, and exposed traverses make it one of the toughest of the South Rim's recommended day hikes. Key waypoints on the way down include Coconino Saddle around the one-mile mark and the trail junction at the bend of the mesa near 2.5 miles, where campsites, vault toilets, and the ruins of the Last Chance Mine cookhouse mark the destination. The mesa itself rewards the effort with sweeping inner-canyon views, scattered mining artifacts, and Cave of the Domes, the only Grand Canyon cave open without a permit.
There is no reliable water on the trail or the mesa, so plan to carry everything you need (roughly 4 liters per person for a day hike). Round-trip is 6 miles and takes most parties 6 to 9 hours, with the climb out demanding noticeably more than the descent. This is non-corridor terrain. Exposure is sustained on the upper sections and the trail is rarely maintained, so it's best suited to hikers comfortable with steep, rough trail and Grand Canyon heat management. Treat the artifacts on the mesa as protected (they are) and stay out of the sealed mine openings.
