Highline Trail: Glacier National Park’s Most Iconic Hike
If you’re looking for a trail that captures the heart of Glacier National Park—sweeping mountain views, alpine meadows, wildlife sightings, and thrilling cliffside paths—look no further than the Highline Trail. This legendary hike delivers everything a backcountry enthusiast could want without requiring technical mountaineering skills. It’s challenging, beautiful, and completely unforgettable.
Trail Overview
- Trailhead: Logan Pass Visitor Center (Going-to-the-Sun Road)
- Distance: 11.8 miles one-way (Logan Pass to The Loop)
- Elevation Gain: ~800 ft ascent, ~2,000 ft descent
- Time: 6–8 hours (one-way)
- Difficulty: Moderate to strenuous
- Season: Mid-July to early October (when snow has melted and the Going-to-the-Sun Road is open)
Note: Most hikers park at The Loop and take the park shuttle up to Logan Pass, then hike back down to their car.
Why Hike the Highline Trail?
From the very first mile, you’re treated to jaw-dropping views of the Garden Wall, deep glacial valleys, and distant peaks stretching into the horizon. You’ll traverse narrow ledges (with cables for support), wander through wildflower-filled meadows, and likely encounter mountain goats, marmots, and maybe even grizzly bears—so be prepared!
A popular side trip is the Grinnell Glacier Overlook, a steep 1.2-mile spur trail (round trip) that climbs straight up the Continental Divide. The payoff? A surreal view into the glacier-carved basin below.
What to Pack for the Highline Trail
Because this is a long, remote hike at high elevation, preparation is key. Here’s what to bring:
Recommended Hiking Gear
- Sturdy Trail Shoes or Hiking Boots
Glacier’s terrain can be rocky and uneven. Opt for breathable, supportive footwear: - Daypack with Hydration Reservoir
You’ll need plenty of water and space for layers and snacks. - Trekking Poles
Help ease the descent and take pressure off your knees. - Clothing Layers
Weather changes quickly at elevation. Bring:- Moisture-wicking base layer
- Lightweight fleece or insulated layer
- Windproof/water-resistant shell
- BALEAF UV Protection Long Sleeve Hiking Shirt
- Sun Protection
High elevations mean intense sun exposure. - Snacks and Hydration
Bring 2–3L of water and high-energy snacks like trail mix, energy bars, or jerky. - Bear Spray
This is grizzly country—never hike without it.
Planning Your Hike
Getting There
The trail starts at Logan Pass, which fills up early. Either arrive by 7:00 AM or use the free park shuttle system from Apgar or St. Mary. Most hikers use the “shuttle-hike” method: park at The Loop, shuttle up to Logan Pass, then hike down to their car.
🏔️ Trail Conditions
Check with the Glacier National Park Trail Status Reports before heading out. Snowfields can linger into July.
🐻 Wildlife Safety
- Carry bear spray (and know how to use it)
- Hike in groups
- Make noise—especially in brushy or wooded sections
Final Thoughts
The Highline Trail is more than a hike—it’s a full-on Glacier National Park experience. With dramatic views, rich wildlife, and an adrenaline-pumping ledge section, it’s perfect for hikers who want a challenge without backpacking.
Whether you’re in it for the scenery, the solitude, or the sense of accomplishment, Highline doesn’t disappoint. Just lace up your boots, pack smart, and get ready for one of the most incredible hikes in the United States.
