The best hikes in Glacier National Park lead through some of the most jaw-dropping alpine scenery in North America, from cliff-hugging traverses to trails ending at glacier-fed lakes. With turquoise water, wildflower meadows, and frequent wildlife, Glacier is a hiker's dream. This guide highlights the top trails, what makes each unforgettable, and how to hike safely in this rugged corner of Montana's Northern Rockies.
Highline Trail
The Highline Trail is Glacier's signature hike, following the Garden Wall along the Continental Divide with nonstop views. Starting from Logan Pass in Glacier National Park, it traverses wildflower slopes and ledges before reaching the Granite Park Chalet. Most hikers arrange a shuttle to walk it one way, and because parking at Logan Pass fills early, plan around Montana's vehicle reservation system and start at dawn.
Grinnell Glacier Trail
The Grinnell Glacier Trail is a bucket-list route climbing past a chain of brilliant blue-green lakes to a viewpoint above the shrinking glacier and its milky meltwater lake. At roughly 11 miles round trip from the Many Glacier area, it delivers some of the finest scenery in the park. Mountain goats and bighorn sheep are common, and a boat shuttle across the lower lakes can shorten the hike.
Hidden Lake Overlook
For a shorter but spectacular hike, the Hidden Lake Overlook begins right at Logan Pass and climbs a boardwalk through meadows to a stunning view of Hidden Lake and Bearhat Mountain. At under three miles round trip, it packs enormous reward into modest effort and is ideal for families. Wildlife sightings are frequent, so keep your distance and carry bear spray even on this popular trail.
Avalanche Lake
The Avalanche Lake trail follows a lush, mossy gorge before opening to a lake ringed by waterfalls tumbling from the cliffs above. Around four to six miles round trip depending on your start, it is one of the most accessible classic hikes in the park and a perfect choice on a day when higher trails are socked in by weather. The old-growth cedar forest at the start is a highlight in itself.
Iceberg Lake
The Iceberg Lake trail rewards hikers with a dramatic cirque where chunks of ice often float on the water well into summer. At about nine miles round trip from Many Glacier, it winds through prime bear habitat and wildflower meadows before the stunning finale. Go early, make noise, and travel in a group, as this trail is well known for grizzly activity.
When is the best time to hike?
Glacier's hiking season is short, generally mid-July through September, once high snow melts and Going-to-the-Sun Road fully opens. Early season trails may be snow-covered at elevation, while September offers golden larches and thinner crowds. Whenever you go, check the current-year rules for road openings, vehicle reservations, and trail conditions before setting out.
