Avalanche Lake

Natural Attrβ˜…β˜…β˜…β˜…β˜†
Last Updated: December 2025

Overview

About This Attraction

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.

Best Time to Visit

Late June through September; photograph with morning light and watch for Going-to-the-Sun Road openings mid-July.

Visitor Tips

  • Arrive before 8am in peak season; parking fills quickly at Trail of the Cedars.
  • Start from the Trail of the Cedars trailhead; round-trip is about 6.0 miles.
  • Bear spray and sturdy boots are essential; download offline maps because cell service is spotty.
  • Stay on the trail; the lake sits behind steep cliffs with slippery roots and rocks when wet.
