Natural AttractionVulture Peak
Glaciated peak with Precambrian Belt rocks; backcountry scramble to the summit.

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.

6,900 ft
Strenuous; not wheelchair accessible
300-ft waterfall; hanging valley; glacially carved granite walls
Ptarmigan Falls cascade; Grinnell Glacier Trail vistas; talus slopes; granite cliffs
Glacial waterfall formed by differential erosion from a hanging valley; lies within the Grinnell Glacier Trail corridor
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.
Gravity hazards from steep drops; no safety barriers at the falls; extremely cold water; bears in area; stay on trail and use bear spray

We had hoped to make it to Iceberg Lake, but we turned around at Ptarmigan Falls due to the wind and rain. We spotted a moose shortly after we got started hiking. On our way back, the sun peeked out and the we received encouragement from a rainbow. We warmed up with hot chocolate next to the fire at Many Glacier Lodge.

We visited this place in July 2022. This water fall is located on the Many Glacier Entrance part of the park. The trail is 2.7 miles one way from the Swiftcurrent Motorn Inn to the falls. It is a 700 ft elevation gain over those miles. It is definitely doable with kids. I just went alone on this one because we had just returned from another trail and the wife and kids wanted a break. The view heading to the falls is great. You can definitely take lots of pictures along the way. When you get to the end of the trail, you arrive at the top of the waterfall. There isn't enough places where you can take good photos of the falls. So what I did was walked back the trail infront of the falls, went off and down the steep mountain for a bit, (don't try it unless you are trained to do those things) and got close enough to and edge where I can have a clear shot at the falls. If you keep walking the trail another 2.6 miles up, you will arrive at the Ptarmigan Tunnel. I didn't go there because it was later in the afternoon and I got back to the parking lot around 6 pm. But if you want to make it to the tunnel, do it early.

The Ptarmigan Falls is a great little rest stop, and it sits right before the turn off to either Iceberg lake, or the Ptarmigan tunnel. The falls can be a little hard to see, but the bridge is pretty cool and the area in general is very nice. It can and does get really busy though is its only downside I suppose. If you are on your way back down it feels really nice to take your shoes off and walk through the water.

Yes. The Grinnell Glacier Trailhead parking fills by about 8:00 AM in peak season; overflow parking at Many Glacier Hotel adds ~1 mile to the hike.
Yes. The 300-foot cascade, hanging-valley setting, and surrounding glacial geology make the effort worthwhile for a quintessential Glacier National Park experience.
The hike is strenuous with exposed sections and uneven footing; assess fitness level and plan extra time; go with companions if possible.
It is a long, strenuous hike with steep segments; consider pacing and rest breaks; not recommended for limited mobility.
No permit is required; you simply hike the Grinnell Glacier Trail to Ptarmigan Falls during the summer season.
