6 miles / Pristine
There are no disappointing trails in Glacier. But to see the place at the apex of its glory—snow-scrubbed peaks, precipitous cliffs, meadows flush with Skittle-colored blooms and gigantic waterfalls—head to the park’s remote northwestern corner. Climb from the shores of Bowman Lake and skirt the vertical headwall of Hole in the Wall, a 1,200-foot hanging glacier valley. You’ll wind up in the snowfield-speckled high country and the cherry on top of the trip: the alpine zone connecting 6,255-foot Brown Pass and 7,478-foot Boulder Pass. Press on to the latter, a 2-mile-long gap dotted with tiny, bright blue pools and eastern views of Thunderbird Mountain, Mt. Chapman, and back down to Hole in the Wall.
