Fish Lake

Starting from the Sperry Trailhead, Fish Lake shares its opening act with one of Glacier's most famous routes before branching off into quieter territory. The first stretch climbs steadily through dense subalpine forest, gaining about a thousand feet over less than three miles — enough to get your heart rate up without destroying your knees. The trail winds through corridors of spruce and fir, with occasional openings that offer glimpses of the surrounding peaks. The payoff is Fish Lake itself, a modest alpine lake tucked into a forested basin where the silence is almost startling after the busier trailheads below. Don't expect the dramatic turquoise of Grinnell — this is a darker, tree-ringed lake with a more intimate feel. Hikers who prefer earning their solitude over chasing Instagram spots will find exactly what they're looking for here.
