Grinnell Glacier Trail

The ideal time to hike is typically from mid-July through September, once the snow has melted from the higher elevations. Earlier in the season, sections of the trail can still be covered in snow and ice, potentially requiring micro-spikes. Be aware that this is an extremely popular hike, especially during peak season.

You can significantly shorten the hike by taking boat shuttles across Swiftcurrent Lake and Lake Josephine. This reduces the round trip distance from approximately 10.6-12 miles to about 7.2 miles, cutting out the flatter initial sections and allowing you to start closer to the main ascent.

The initial miles from the trailhead are relatively flat, passing through forests with views of the Many Glacier Hotel. After Lake Josephine, the trail begins a steady uphill climb, becoming rockier and more exposed. The steepest part is near the end, with stone steps and rocky switchbacks leading to the glacier viewpoint. You'll walk over ancient sea floor and through a U-shaped, glacier-carved valley.

The trail offers breathtaking scenery, including vibrant turquoise waters of Grinnell Lake and Lake Josephine, fed by glacial flour. You'll pass Grinnell Falls and get up close to the Grinnell Glacier itself. Other highlights include Swiftcurrent Lake Trail West and the Morning Eagle Tour Boat at Lake Josephine.

The trail is known for excellent wildlife viewing opportunities. Keep an eye out for mountain goats, bighorn sheep, and occasionally moose or bears. Remember to maintain a safe distance and never feed wildlife.

The trailhead is located in the Many Glacier area of Glacier National Park. Parking at the trailhead can be very limited and often fills up extremely early in the day, especially during peak season. Arriving before 7 AM is often recommended. Alternatively, you can utilize the park's shuttle system or the boat shuttles across Swiftcurrent Lake and Lake Josephine to access the trail.

The lower portions of the trail may offer some shade, but as you ascend to higher elevations, the trail becomes very exposed. The upper sections have little to no shade, meaning significant exposure to sun, wind, and potential rain. Be prepared with sun protection, layers, and plenty of water.

Yes, the route covers a significant portion of the Grinnell Glacier Trail itself (42%) and also passes through sections of the South Shore Josephine Lake Trail (25%), North Shore Josephine Lake Trail (19%), and Swiftcurrent Lake Trail (10%).
