The Loop Trailhead
Last Updated: December 2025
Overview
About This Trail
The Loop Trailhead offers a steady, non-technical climb through forest with rewarding views. Parking is tight, and shuttle may be required during peak season, so plan ahead.
Highlights
Difficulty Level
Strenuous to challenging (depends on Highline linkage)
Hike If / Skip If
A hiker with solid aerobic fitness who can sustain a steady pace for 2–3 hours (fit hikers) or 3–4 hours (casual hikers). Comfortable with a 700-foot gain over 3.2 miles and prepared for bear country with bear spray. Suitable for solo travelers or small groups, provided you bring adequate water, layers, and a map.
Trail Highlights
Panoramic views of mountains, valleys, and glaciers; Grinnell Glacier Overlook
The Sweat Reality
Moderate workout: 3.2 miles round trip with about 700 feet of elevation gain. It isn’t technical, but the steady climb will test endurance. Plan 2–3 hours for fit hikers and 3–4 hours for a more relaxed pace.
The Arrival Protocol
The trailhead sits along Going-to-the-Sun Road at the west end of the Loop. Parking is a small pullout with very limited spaces and tends to fill by around 7:00 AM in peak season, so be prepared to circle or shuttle. During times when the road is fully open, a shuttle is required to access the trail. Arrive early or consider alternative access options if parking is full.
The Payoff
Photo opportunities include forested sections in the first half with filtered light, then rocky portions as views open up toward the surrounding peaks and the road corridor. Use a mid-range lens to capture distant ridges and a tripod for low-angle light in shaded areas or at dawn/dusk.
Insider Tips
• Start before sunrise to secure parking and cooler temps. • Hike the Highline Trail Logan Pass to The Loop Trailhead, then use the shuttle to return. • Trekking poles strongly recommended for the descent; plan for afternoon thunderstorms.
Best Season to Hike

Hiking Tips
