See that bowl-shaped basin? That's a cirque carved by a passing glacier. Deep Time shows this valley was sculpted during the last ice age, leaving the meltwater-fed lake in a trough. The rocks here are hard granite and dark metamorphic layers, polished by ice; gravity still nudges the shore, so stay back from the edge.

Avalanche Lake was absolutely gorgeous and worth the hike! The trail is about 2 miles each way and not too difficultβshaded, with streams and waterfalls along the way, so it stays interesting. When you finally reach the lake, the view is stunning: turquoise water surrounded by tall cliffs and multiple waterfalls cascading down into it. It felt peaceful and refreshing, even with other hikers around. Tip: Go early to avoid crowds and bring water/snacksβyouβll want to stay and enjoy the view for a while. Definitely one of my favorite spots in Glacier National Park!

We combined this with the trail of the cedars. My alltrails said 7.1 miles and my wifes apple watch said 7.5 when all was said and done but I had heard it was 5.9 beforehand. Either way, all ages and sizes were accomplishing this hike although most everyone we saw were taking breaks. We were able to do this without taking breaks besides photo ops and spent some time at the lake, exploring. The incline is slow and steady, totaling around 600-700' when done, with barely any of it on the way back. I highly recommend hitting the fishing trail as soon as you see the lake, but also walking to the other side of the lake. The views from both ends are breathtaking. We got here around 630am on a Wednesday morning in early August, the lot was over half full with cars parking every few seconds. This is one of the more popular hikes. The lot is always full after 7am and you have to wait for spots.

Beautiful, well-maintained trail with stunning views from start to finish. The hike winds through lush forest along Avalanche Creek, and ends at the breathtaking Avalanche Lake β crystal-clear water, towering cliffs, and waterfalls. We even spotted a deer and marmot along the way. A must-do in Glacier National Park!

Yes. Parking at Trail of the Cedars and Avalanche Picnic Area fills very early in peak season; overflow parking may be down the road.
Yes. The lake sits in a glacially carved cirque, with a calm shoreline, forested slopes, and potential wildlife sightings that reward the effort.
The data here doesnβt specify; check Glacier National Park policies before bringing pets to trail sections beyond the Cedars boardwalk.
Only the first half-mile of the Trail of the Cedars is wheelchair-accessible; the remainder is steep and rocky, so plan accordingly.
The water may appear blue-green due to depth and glacial flour; in person it can look jewel-toned especially where sunlight hits the lake surface.
Bear activity is normal in this region. Carry bear spray, stay aware of surroundings, and maintain distances if you encounter wildlife.
No permit is noted for the Avalanche Lake hike itself; a standard Glacier NP park pass is typically required for entry.
