Iceberg Lake – Glacier National Park

Iceberg Lake is a 9.6-mile out-and-back hike located in the Many Glacier area of Glacier National Park. This hike is one of the most popular in the park, leading to a stunning alpine lake that, thanks to the shade of Mount Wilbur, stays cold enough for icebergs to float in its waters year-round.

Trail Highlights

One of the best parts of this hike is that there are breathtaking views the entire way. While another popular hike in this area, Cracker Lake, centers on the lake as the main attraction, Iceberg Lake offers continuous scenery that keeps you in awe throughout the journey. By the time I reached the lake, I thought the hike couldn’t possibly get any better—and then I saw the spectacular alpine lake with its brilliant turquoise water and floating icebergs. It truly is an unforgettable experience.

Difficulty Level

We rated this as a moderate-difficulty hike. While there is some elevation gain, it’s spread out over the course of the hike, making it manageable. For those accustomed to mountain hiking, it won’t feel too challenging.

Wildlife Encounters

If you’re hoping to see wildlife, the Many Glacier area is one of the best places in Glacier National Park. Over the years, I’ve encountered mountain goats, bighorn sheep, black bears, grizzly bears, and, on my hike to Iceberg Lake, I saw my first moose. My daughter spotted it in the brush below us. It was an incredible moment and one I’ll never forget.

Getting There

The Many Glacier entrance is located in the northeast corner of Glacier National Park. If you’re traveling from towns west of the park, such as Kalispell, Columbia Falls, Whitefish, or Bigfork, plan for a bit of travel time. From Columbia Falls, it typically takes about 2.5 hours to reach the Many Glacier entrance. From Kalispell, add another 30 minutes.

This is a busy area of the park, and parking can fill up quickly during peak hours. It’s best to arrive early in the morning or later in the afternoon to avoid the crowds. Just ensure you leave yourself enough time to return before sunset if you want to avoid hiking in the dark.

Things to Know Before You Go

In recent years, Glacier National Park has seen a significant increase in visitors, especially post-COVID. To manage this influx, the park has implemented vehicle pass requirements for many areas. For 2025, these areas will also require a timed reservation. Each year, the process has evolved and, unfortunately, become more complex. Be sure to research current reservation and pass requirements before your visit.
