Low altitude with big relief, the Belly River Valley in Glacier’s little-visited northeast corner opens when other Glacier hikes are still choked with snow. At the trailhead just 200 yards short of the Canadian border, head downhill on the Belly River Trail. Make plenty of noise—this is Grizzly county—as you drop 800 feet through lush aspen and an overlook of the river at mile 3.
On the valley floor, look west across wildflower-sprinkled fields toward Sentinel and Bear mountains and south toward Cosley Ridge. At mile 5.6, skip the spur toward Gable Creek Campground and turn right on the Cosley Trail toward a bouncing suspension bridge.
Two miles later, detour for a 100-foot spur trail to an overlook of Gross Ventre Falls and finish day one’s last 1.3 miles with a rolling meadow traverse above the Mokowanis River. Bypassing the Bear Mountain Overlook Trail—a great sunset side-trip—to set up at one of Cosley Campground’s four lake-side sites.
On day two, backtrack .6 miles to the Ptarmigan Trail for a cable-assisted crossing of Cosley Lake’s outlet. You’ll traverse a forested ridge toward a .3-mile round-trip detour to a 50-foot cascade at Dawn Mist Falls. Continue 1.5 miles south to the gravel shore of Elizabeth Lake and camp in the shade of lodgepoles nestled between Ptarmigan Wall and Seward Mountain’s Red Gap Pass.
Begin day three by backtracking to a suspension bridge, but continue north on the Belly River Trail for a back-side view of Chief Mountain. It’s a mellow descent to the ranger station’s horse pasture where the trails merge and head back through the river valley toward the base of the trailhead-bound climb.
