Overview
The Teton Crest Trail's southern section, approached from Targhee National Forest on the Idaho side, offers one of the most dramatic backcountry routes in the Rockies. Unlike the crowded Wyoming approach via Grand Teton National Park, the Teton Canyon trailhead on the forest's west slope provides a quieter entry point into the same stunning terrain.
The route climbs through Teton Canyon to Alaska Basin, a high glacial cirque ringed by jagged Teton peaks with scattered alpine lakes and carpet wildflower meadows in July. The trail then continues up steep switchbacks to Hurricane Pass at 10,372 feet, where the sheer face of the Grand Teton and Middle Teton fill the eastern horizon. From there, the route enters Grand Teton National Park territory.
The Route
From Teton Canyon Trailhead, the trail follows Teton Creek upstream through lodgepole and spruce forest for the first 3 miles before entering the Jedediah Smith Wilderness. The gradient steepens as the route climbs into Alaska Basin, reaching the basin's lower lakes around mile 5. A side loop through the basin adds significant mileage but explores additional lake basins and rock-strewn terrain. The main route continues to Hurricane Pass and the park boundary.
What to Expect
This is high-altitude, exposed alpine terrain. Afternoon thunderstorms are common in July and August. Permit logistics and the need for a vehicle shuttle make this a trip requiring advance planning. The views from Hurricane Pass looking east into Grand Teton National Park rank among the finest in the Rockies.
Nearby
The Moose Creek Trail offers a shorter alpine outing from Targhee. The town of Driggs, Idaho serves as the primary gateway with full services including lodging, gear shops, and restaurants.
Leave No Trace
This trail receives enough use that following Leave No Trace principles is important for preserving the experience for future visitors. Stay on the marked trail to prevent erosion. Pack out all waste. Avoid camping within 200 feet of water sources or the trail. Use existing fire rings only where campfires are permitted, and check current fire restrictions at checking conditions before you go before any visit. The trail and surrounding terrain remain in good condition because previous visitors have respected these norms.
Safety Considerations
The strenuous rating reflects the trail's general character under typical conditions. Weather, seasonal snow, and trail conditions can change the experience significantly. Carry the 10 Essentials on any full-day outing. Inform someone of your plans and expected return time before heading out, particularly on longer or more remote trails. Cell service varies throughout Targhee National Forest and may be unreliable in canyon bottoms or remote terrain.
