Garnet Canyon Trail, Mountain trail in Grand Teton National Park, Wyoming, US

Garnet Canyon Trail is a mountain path in Grand Teton National Park that cuts through forest and rocky ground. The route climbs steadily upward and ends where the terrain transitions into boulder fields and loose scree.

The Garnet Canyon Trail begins at the Lupine Meadows parking area and forks from the Amphitheater Lake Trail at the 2-mile mark. It climbs more than 2,500 feet into Garnet Canyon, becoming unmaintained in boulder fields near 9,500 feet. Climbers continue to the Lower Saddle at 11,600 feet, a gain of nearly 5,000 feet from the trailhead.

The trail serves as the traditional gateway for climbers attempting the region's highest summits. Visitors notice evidence of this climbing heritage in the marked routes and the camps scattered across the upper elevations.

The hike starts from the Lupine Meadows parking area and grows steeper and more demanding as you advance. Visitors should arrive early, wear proper footwear, and bring plenty of water.

Above where the standard path ends, extensive boulder fields spread across high elevation, making travel more difficult. This zone marks where the route transitions into true mountaineering terrain.
