Info from GNP web site "Iceberg Lake Trail posted for hazardous travel conditions near Ptarmigan Bridge"

iceberg lake 6-23-13

The trailhead is behind the Swiftcurrent Motor Lodge, take the last right hand turn before the end of Many Glacier Road.
There is a small parking area for Iceberg Trail at the trailhead.

Ptarmigan/ Iceberg Trail Motel parking lot to jct. above Ptarmigan Falls/ 2.4 mi.
Trail posted for hazardous conditions.
Recent storm washed out 40 feet of trail by Henkel Creek.
Mud and scree slides deposited several debris piles 4 feet high on other sections. 6/21/13

Jct. above Ptarmigan Falls to Iceberg Lake/ 2.1 mi.
Initial clearing scheduled for: 6/28/13
Footbridge scheduled to be installed 6/28/13
Trail is snow-free for the first 3/4 mile beyond the falls.
The last 1.5 miles is mostly snow covered with some potentially hazardous snow field crossings, 6/18/13

Unless you are at the trailhead early in the morning you will need to park in the main parking lot. Swiftcurrent Restaurant opens at 6:30 am for breakfast. Drinking water available in Many Glacier Campground along with flush toilets. Last toilet before Ptarmigan Falls. There is a second pit toilet on the trail just before Iceberg Lake. This trail is through bear country! Bear Bells DO NOT WORK and are an annoy to other hikers. Bear Spray does work. When hiking in bear country make noise when going around blind corners. During the main hiking season there are free Ranger Led Hikes. Depending on the Ranger you will learn about the geology or plant life in the area. Hike schedules change during the summer so pick up a current copy when you enter the park.

If you are not an experienced back country hiker I highly recommend these hikes.

The steepest portion of this trail is the start which is a series of switchbacks. Once you have finished the switchbacks the trail makes a very gradual ascent hugging the side of Henkel Mountain. During the start of the 2013 hiking season Many Glacier received 3 inches of rain in two hours. This is the same storm system that caused massive damage to Calgary and Banff. Luckily for the Many Glacier area the focus of the storm was basically limited to Henkel Mountain. As mentioned elsewhere I hiked the Iceberg Trail three days after this deluge. Swiftcurrent Lake was a muddy brown. At the start of the Iceberg Trail there was no noticeable damage until I reached Henkel Creek which in the past was not even noticeable as I can find no photos from all of my previous hikes of the Iceberg Lake Trail. After making my way across the gouged out creek bed I encountered tall piles of scree that had been dumped onto the trail. I will hike to Ptarmigan Tunnel next year which shares the first have of the Iceberg Trail to record the repair work done by Glacier Parks hard working, unsung heroes. (well my regular readers will know that I sing praise for the trail crews on a regular basis!)

Unless you are an experienced winter hiker I'd think twice before crossing this creek when it is covered by an unstable snow bridge.
See photo of creek crossing in early September on the right side of this page.

Red Rock Falls on the Swiftcurrent Trail is an easy hike with great views.


Iceberg Lake Trail is one of the more popular trails in Glacier Park. Iceberg Lake Trail is usually a very crowded trail. Wildflowers are spectacular this year, 2013, on this trail. Iceberg Lake Trail is very frequently closed because of bear activity. This is a very active grizzly bear (Ursus arctos horribilis) corridor.

On most trails in Glacier Park bugs aren't a problem. Iceberg Lake Trail is usually a very buggy trail.

The steepest part of Iceberg Lake Trail is at the trailhead, after the initial climb the trail ascends to Iceberg Lake very gradually.

Bugs along with snowfall were setting new 'records' in Glacier Park 2011!


2010/2011 was a record breaking heavy snowfall year!
Don't expect this trail to be clear of all snow until early August 2011!

2009/2010 was a light snow year.
2008/2009 was a heavy snow year. This trail wasn't completely clear of snow until mid July.

Small Iceberg on Iceberg Lake, July 2005, compared to the icebergs in Upper Grinnell Lake these guys are ice cubes! Of all the trails I've hiked in Glacier Park this is the buggiest.

Drowning is the NUMBER 1 cause of visitor deaths in Glacier National Park.
Ten times as many people have drowned then have been killed by bears.
The water in Iceberg Lake is very, very cold.

wildflowers iceberg lake trail glacier national park



Iceberg Lake July 2005 was for me the year of the flowers. The wildflowers below were taken on the meadow next to Iceberg Lake. The amount of wildflowers blooming varies greatly from year to year.

These flowers were taken on the Ptarmigan Tunnel Trail a few days before. I've lost track of how many times I've hiked the Iceberg Lake Trail.

Iceberg Lake Trail Damage

Will put together a web page on storm damage this winter. All reports that I get from hikers is that the trail is fixed.
