Ptarmigan Falls

Overview

About This Attraction

A white curtain of Ptarmigan Falls pours over a sheer lip, the cascades framed by pale granite along the Grinnell Glacier Trail. Morning light makes the water sparkle as it drops into a hanging valley carved by ice over millennia. This is a glacial waterfall—the direct result of Pleistocene glaciation and differential erosion.

Best Time to Visit

July and August bring the strongest flow from snowmelt and are the busiest months; the trails are generally snow-free then. Late June can also have high water volumes, though some high-elevation sections may still be snowed in. For photography, aim for the morning or late afternoon when the light is softer and glare is reduced; midday sun can wash out the spray.

Visitor Tips

  • Arrive before 8am; Grinnell Glacier Trailhead parking fills quickly.
  • Expect a strenuous 7-mile round trip; allocate 4–6 hours.
  • Water is not available on the trail; carry ample water or filtration.
  • Bear spray recommended; stay alert and travel in groups.
  • There are no barriers at Ptarmigan Falls; keep distance from cliff edges.
  • Cell service is unreliable along the Grinnell Glacier Trail; download maps offline.
