The Ice Lakes Trail offers a lot of variety. It leads you through old-growth forest to subalpine meadows, to alpine tundra and views of mountain lakes and rugged 13,000+ peaks. The trails climbs through 2 basins, each with its own ecosystem. On the way up to the first basin you will pass a Clear Creek waterfall on the right and an old mill off to the left. After 2 miles of climbing, the trail traverses through the Lower Basin. The trail concludes at Ice Lake, which is the bluest lake you will ever see. During July and August, you will pass through a stunning array of flowers at each level.
If you have the time and energy to explore more of the upper basin area before returning to the trailhead, two popular side trips are to Island Lake and Fuller Lake. These are non-system trails that are not maintained by the San Juan National Forest. Please use caution and travel at your own risk.
Side Trip Options:
- A side trip to Island Lake to the northeast adds about 1.12 miles round trip and 130′ elevation gain. This lake with a unique island, is in its own cirque surrounded by U.S. Grant Peak and its ridges.
- A side trip to Fuller Lake to the south adds about 1.75 miles round trip and 335′ elevation gain. An old collapsed metal-sided mining cabin with an adjacent picnic table stands beside the lake.
Note of caution:
Be very cautious when hiking the trail where it transitions from the lower basin to the upper basin and vice versa. This is a rocky section with a drop off that could be challenging for some.
Ice Lakes Highlights:
- Activities to enjoy in the area include hiking, trail running, backpacking, mountaineering, photography, fishing, and wildlife, wildflower and scenery viewing.
