If you’ve ever dreamed of hiking to a pristine alpine lake filled with floating icebergs, then Iceberg Lake Trail in Glacier National Park needs to be at the top of your list. Located in the stunning Many Glacier region, this hike combines jaw-dropping scenery, wildflowers, and a glacier-carved destination that feels like another planet.
Whether you’re a seasoned hiker or just up for a scenic challenge, Iceberg Lake is a hike that leaves an impression long after your boots are off.

Why Hike the Iceberg Lake Trail?
Because it looks like something out of a fantasy novel.
The hike begins with expansive views of the Many Glacier Valley, then climbs gradually through meadows filled with wildflowers, past waterfalls and cliff faces. You’ll likely spot mountain goats, marmots, and maybe even a grizzly bear (so come prepared).
The final payoff is Iceberg Lake—a turquoise gem nestled beneath towering cliffs, often scattered with actual icebergs well into August. On a calm day, the reflection alone is worth the mileage.
