The Many Glacier area of Glacier National Park is full of great hikes, and the Iceberg Lake Trail is definitely one of the best. The reward doesn’t come easy, though. At just under 10 miles (round trip), you’ll have to work to get there. However, for those that are willing to take on the trip, they’ll enjoy breathtaking scenery along the entire route, a waterfall, several river crossings and an emerald-green, glacier-fed lake, complete with icebergs!
Hiking 10 miles is not something that our family typically does, and as you can imagine, our kids are not usually overly excited to head out on a hike this long. However, this turned out to be one of our favorite hikes of the park!

PARKING AND TRAILHEAD FOR THE ICEBERG LAKE TRAIL
The Iceberg-Ptarmigan Trailhead is in the Many Glacier area of the park. To access Many Glacier, head north from St. Mary, MT on Highway 89 to Babb and then follow signs west to Many Glacier. After arriving in Many Glacier, continue past the Many Glacier Hotel toward the Swiftcurrent Motor Inn.
Iceberg Lake Trail Maps and Parking from the National Park Service
There are two options for parking. The main parking area for the trail is northwest of the Swiftcurrent Motor Inn. This parking area is small (only about 15 spots) so an alternative is to park in the lot for the Swiftcurrent Motor Inn. This parking lot requires a short 3-minute walk to the trailhead and there are many spots available (with a high amount of turnover, so just drive around for a few minutes if you can’t find a spot).
Clean restrooms (with running water) are located in the small visitor center in the front of the Swiftcurrent Motor Inn. Since the trail takes about 5 hours to complete, you’ll want to make sure you stop here first!
THE HIKE TO ICEBERG LAKE
The trail starts in a forest and then heads immediately uphill. In fact, the trail climbs 1,500 feet for the first 3.6 miles before it flattens out for the last mile. The trail never feels really steep. After the first 0.3 miles of the hike (which has the steepest climbing), you are in for a gradual uphill the rest of the way. Don’t be afraid-the climb is relatively easy and ends quickly.
Once you settle into the hike, you’ll find yourself hiking along the south side of Mount Henkel. For the duration of the hike, you’ll have wonderful views of Mount Wilbur to the southwest and Iceberg Peak (which is right behind your final destination) to the west.
Along the trail there are nine water crossings. The river crossings are either very small (barely getting the soles of your feet wet) or have a small footbridge to make it easy.
While hiking, the trail alternates between being in a forest and in open brush. The mix is nice, and the forest provides some much-appreciated shade. On a hot day, which is common on the summer, taking a break in the shade is a great way to help recover from the sun.
Take some time to stop and appreciate the wildflowers. In July, they were in bloom and quite beautiful!
After approximately 2.7 miles, you’ll come up on Ptarmigan Falls. Ptarmigan Falls is beautiful, but a bit underwhelming if you decide to stop here. We recommend taking a break in the shade, taking some pictures and resting up a bit in the cool shade before continuing the last 2.1 miles.
A few hundred feet past Ptarmigan Falls, the trail comes to a split. The Ptarmigan Trail forks to the right for hikers wanting to go to Ptarmigan Lake. To get to Iceberg Lake, stay to the left. If you have to make a quick pit stop, there is a pit toilet here as well.
This part of the trail flattens out after the first mile (at this point, you have one mile to go!).
Depending on the time of year, you should be prepared for some snow crossings along the way, particularly as you get closer to Iceberg Lake. We hiked in the middle of July and while the snow was almost gone we still had to be careful to avoid slipping.
Be prepared to be amazed-as you approach Iceberg Lake you’ll catch your first glimpse of this well hidden oasis!
Iceberg Lake sits at the bottom of Iceberg Peak, towering over 3000 feet above the lake. The lake gets its name from the icebergs that are present year-round, which fall from above. The lake has an amazing blue-green color, and if you look closely you can see the icebergs moving ever-so-slowly if the wind is blowing.
If you wait long enough, you may be lucky enough to experience a small rockslide, which booms and echoes like you wouldn’t believe! This happened right as we arrived at the lake and it was incredible.
Take your time at the lake and enjoy the view. Stick your feet in the water if you dare! The water is near freezing, even close to the shoreline.
If you must, there is a pit toilet at the lake, marked by signs just west of the trail.
THE RETURN TRIP
The hike back is easy, aside from the length. The views are beautiful the entire way, and it will take about 20 minutes less due to the downhill slope.
- The trail is exposed for at least half of the hike, so you’ll want to make sure you wear sunblock. We have to use sunblock that is good for sensitive skin, and the one that we found that we like that doesn’t break the bank is No-Ad SPF 45.
- Bears are all around in Glacier National Park, and it’s not rare for trails to be shut down in the middle of summer due to activity. To hike without bear spray is like playing Russian roulette, and we highly advise picking up some ahead of your visit to the park or at a ranger station while you are in the park. The one that we carried with us (and didn’t use) is the Counter Assault Pepper Spray.
- The bugs on this trail were not awful, but parts of the park are known for having pretty intense mosquitoes that are ready to greet you around every corner. Our favorite bug spray is Squito Ban from Yaya (as it is all natural), but if you prefer something with Deet, then this option from Repel is great.
- Carrying water on these long hikes is a must, and we recommend the Platypus pack.
- This hike is popular, but the length tends to keep crowds away. We arrived early in the morning, which made the trail fairly quiet until the return trip.
