Iceberg Lake Trail is one of the more popular trails in Glacier Park. Iceberg Lake Trail is usually a very crowded trail. Wildflowers can be spectacular 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. 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. 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 are setting new 'records' in Glacier Park this year!


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.

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. 2005 was the last year that I hiked Iceberg Lake Trail, trying to get to other trails that I haven't ever hiked.
