About This Route
The Highline Trail in Glacier National Park stands as one of the most iconic and challenging hikes in the United States, stretching 11.6 miles one way from Logan Pass to Granite Park Chalet. With stunning panoramic views of the Garden Wall, this exposed ridge trail offers glimpses of mountain goats, wildflowers, and distant glaciers. NPS recommends early starts to avoid afternoon thunderstorms, and the trail follows the Continental Divide with sheer drop-offs on one side. Expect 3,000 feet of elevation gain overall, making it a strenuous day hike or overnight with permits. Follow Leave No Trace principles by packing out all waste and staying on the narrow path to prevent erosion.
Safety Considerations
Weather shifts rapidly above the treeline; sudden snow squalls or lightning can occur even in July. Bears, including grizzlies, frequent this area, so carry bear spray and make noise around blind curves. The narrow ledge along the Garden Wall has prompted NPS to install a metal cable handline in spots, but slips remain deadly due to 1,000-foot exposures. Dehydration hits fast at 6,600 feet elevation; drink at least 1 liter per 2 hours. Hypothermia risks spike if crossing swift streams like those near Granite Park; avoid fording alone per NPS guidelines. Watch for mountain goats charging if you get too close, as documented in recent incidents. Solo hikers should join ranger-led groups during peak season.
Essential Gear
Pack layers from REI Co-op's Magma sleeping bag liner for warmth, a waterproof jacket like Patagonia Torrentshell, and sturdy boots such as Salomon Quest 4 GTX for rocky terrain. Include a National Geographic Trails Illustrated map for Glacier's Going-to-the-Sun Road corridor, Garmin inReach satellite communicator, and UDAP Bear Bait & Fight bear spray holstered for quick access. Trekking poles like Black Diamond Trail Ergo Cork reduce knee strain on descents. A wide-brim hat and high-SPF sunscreen combat intense UV at altitude.
