Monument Falls

Monument Falls cascades down a rugged Glacier National Park cliff, with snow patches and evergreen slopes beneath a deep blue sky.

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.

Frequently asked questions

Do I really need to arrive before 7am to get parking?

Yes. Parking fills very early in peak season; aim to arrive before mid-morning or use overflow options and carpool.

Is it worth the 4.5-mile hike just to see Monument Falls?

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.

Can I bring my dog to the Monument Falls area?

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.

Is the viewing area safe for families?

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.

Will the trail be accessible for someone with limited mobility?

Direct access to Monument Falls isn’t wheelchair-friendly; the Trail of the Cedars offers accessible sections, but the hike to Avalanche Lake involves uneven terrain.
