A 215-foot curtain of water pours into the cold pool of Avalanche Lake. Spray fogs the shoreline as meltwater from Sperry Glacier hammers the drop, throwing rainbows in the late afternoon light. This scene is erosion in action: water gnaws at rock over Deep Time, shaping a dramatic fall in Belt Supergroup geology. Monument Falls, seen from the Avalanche Lake shore, is a live textbook of glacial-era meltwater sculpting.
Early summer through September for peak meltflow; late afternoon light during golden hour.

Beautiful falls! Best viewed from Avalanche Lake.

Amazing!
Yes. Parking fills very early in peak season; aim to arrive before mid-morning or use overflow options and carpool.
Yes. The hike to Avalanche Lake frames Monument Falls within a glacially sculpted setting, and the falls themselves present a clear example of continuous erosional work by meltwater.
Dogs are allowed on some Glacier trails, but Monument Falls viewing is on the Avalanche Lake shore with uneven terrain; keep dogs on leash and be mindful of wildlife corridors and safety.
There are no direct barriers at Monument Falls; stay on designated trails and away from edges, and supervise children closely around wet, mossy rock and cold water.
Direct access to Monument Falls isnβt wheelchair-friendly; the Trail of the Cedars offers accessible sections, but the hike to Avalanche Lake involves uneven terrain.
