Marion Lake Trail

Overview

This is a demanding backcountry loop to one of the Tetons’ quieter gems: Marion Lake. Expect a full-value day with big views, wildflower meadows, and a serene subalpine lake ringed by granite. It’s generally less crowded than front-country classics, but it’s no pushover.

Route & Stats

Plan on a 14.2-mile total loop with about 3,838 feet of elevation gain. Most hikers ride the Jackson Hole Aerial Tram from Teton Village to start high, then link sections of the Teton Crest Trail toward Marion Lake before looping back through Granite Canyon. Junctions (including cutoffs between the Middle and North Forks) come quickly—bring a map or GPS and pay attention to signage. Stream crossings, steep grades, and a short climb to the lake’s bench keep this firmly in the strenuous category.

Scenery & What You’ll See

You’ll traverse broad alpine meadows that explode with wildflowers in late July, with sweeping vistas toward Rendezvous, Fossil, and Housetop Mountains. Marion Lake itself sits in a cirque below granite walls—peaceful, blue, and photogenic. Keep an eye out for moose in lush meadows and marmots sunning on rocks along the Crest.

Trail Experience

The high start makes for immediate big-mountain feel, but you’ll earn every view with punchy ups and downs. Sections between the North Fork and the lake are particularly taxing. Expect rugged singletrack, rocky stretches, and a few creek crossings. Navigation can be mildly tricky where trails braid—another reason to start early and give yourself buffer.

Best Time to Hike

Mid-July through September is your sweet spot, once lingering snow has melted. Wildflowers peak in late July. Start early to beat common afternoon thunderstorms and to keep a comfortable margin for the loop. Tram operating hours and weather can dictate your window; weekdays are typically quieter, though this route is “not crowded” by Teton standards.

Tips, Camping, and Regulations

Carry layers for fast-changing alpine weather, plenty of water and calories, and trekking poles for steep grades and crossings. Bear spray is a must. There’s a designated backcountry campsite east of Marion Lake if you’re backpacking—permits are required for overnight use. No permit is needed for day hiking. Pets are not allowed on this trail.
