South Teton

Overview

South Teton is a 12,514-foot summit tucked above the South Fork of Garnet Canyon. It’s part of the historic Trois Tetons trio and, while overshadowed by the Grand and Middle, it often offers a quieter summit experience with equally jaw-dropping views. Many consider it one of the easier major summits in the range, but don’t underestimate it—this is real alpine terrain.

Route & Difficulty

Most parties approach from Lupine Meadows up Garnet Canyon to the South Fork. The regular line is the Northwest Couloir. Expect a big effort—roughly a 6,000-foot climb—on a route that shifts from trail to talus and scree with Class 2–3 scrambling. From the saddle between Middle and South Teton, a faint scree path weaves to the ridge; plan on under an hour to tag the summit and about 45 minutes back to the saddle if conditions are dry.

What You’ll See

From the top, the Grand and Middle Teton dominate the skyline, with Cloudveil Dome and the western Teton Basin sprawling beyond. It’s a panorama that feels close to the heart of the range without the usual crowd that flocks to the Grand.

Season & Conditions

Prime season runs June through September, but lingering snowfields can stick around well into summer. Start early to bank daylight and dodge typical afternoon thunderstorms. Weekdays tend to be quieter, and the Lupine Meadows trailhead is popular enough to fill early on weekends.

Logistics & Permits

No permit is required to climb South Teton as a day trip. If you plan to overnight in Garnet Canyon, you’ll need a backcountry camping permit. There are no amenities at or near the peak—no restrooms, water, or facilities—so carry everything you need and be prepared to treat or pack in water.

Wildlife

This is classic high-alpine country. Keep an eye out for small alpine mammals and soaring raptors, and use standard backcountry awareness on the approach through Garnet Canyon.

Best Time to Visit

• June–September for best access and longer days.
• Early starts for safer weather windows and easier parking.
• Midweek for more solitude and a calmer summit vibe.
