Iceberg Lake Trail

The Iceberg Lake Trail begins in the Many Glacier area of Glacier National Park. The trailhead is located behind the Swiftcurrent Motor Inn. Parking can be very challenging, especially during peak season. It's highly recommended to arrive early in the morning, ideally before 7 AM, to secure a spot. There is also a shuttle service available within the Many Glacier area, which can help reduce parking stress.

The roundtrip hike to Iceberg Lake is approximately 9.3 to 9.8 miles. Most hikers complete the trail in about 5 to 6 hours, depending on their pace, how long they spend at the lake, and stops for photos or wildlife viewing.

The trail is generally rated as moderate to difficult due to its length and overall elevation gain of 1,200 to 1,275 feet. While the initial quarter-mile is the steepest, the rest of the trail has a more gradual incline. It's not technically challenging, but the distance can be tiring for less experienced hikers or young children. Families with older, experienced hikers should be fine, but it might be too strenuous for very young children or those new to hiking long distances.

The trail offers diverse and scenic terrain. You'll hike through old-growth forests, open meadows filled with wildflowers, and along the base of the dramatic Ptarmigan Wall. The path is well-maintained but can be rocky in sections. Expect varied surfaces, from packed dirt to some uneven rocky areas.

The Iceberg Lake Trail is known for frequent wildlife sightings. Hikers often spot black bears, grizzly bears, moose, deer, mountain goats, and bighorn sheep. It's crucial to carry bear spray, know how to use it, and make noise while hiking to avoid surprising animals.

The best time to hike the Iceberg Lake Trail is typically from mid-July through early September. During this period, the trail is usually snow-free, wildflowers are in bloom, and the weather is generally pleasant. Even in summer, you'll likely see icebergs floating in the lake, which is a unique sight.

No, dogs are not permitted on the Iceberg Lake Trail or any other hiking trails in Glacier National Park. This policy is in place to protect wildlife and ensure visitor safety. Dogs are generally only allowed in developed areas, along paved roads, and in campgrounds.

While you don't need a specific permit for the Iceberg Lake Trail itself, you do need to pay the entrance fee for Glacier National Park. During peak season (typically late May through early September), a vehicle reservation may also be required for the Many Glacier area, where the trailhead is located. Always check the official Glacier National Park website for the most current entrance fees and reservation requirements before your visit.

Yes, the route to Iceberg Lake shares sections with other trails. You will be on parts of the Ptarmigan Trail and the CDT - Idaho & Montana Section for portions of your hike.

The most distinctive feature of Iceberg Lake is its ability to retain floating icebergs well into the summer months. This is due to its location in a deep cirque, surrounded by tall cliffs that limit direct sunlight, allowing snow and ice to persist much longer than in other areas. This creates a truly spectacular and memorable scene.
