“If you see one of Glacier's long red tour buses, you're looking at a design from the nineteen thirties. The historic fleet was built between nineteen thirty-six and nineteen thirty-nine.”

Hiking Sherburne Boundary Trail

A short, steep out-and-backSherburne Boundary Trail is a 3.

Sherburne Boundary Trail is a 3.1-mile round trip from the Lake Sherburne Dam outlet to a small meadow at the top of Boulder Ridge. The mapped path is about 1.55 miles each way and climbs roughly 960 feet; allow about three hours to go up and return. It suits hikers looking for a hard, steep climb more than a big-view destination: the forested climb has no views, and the ridge-top views are limited.

Finding the unsigned startThe approach begins at the outlet side of the dam.

The approach begins at the outlet side of the dam. Follow its base to the far side, then take the road east and north to the unsigned path heading southeast. Current legal access to this dam-side approach has not been confirmed; check with the park before setting out. This route’s actual start is unsigned, so do not expect a marked trailhead.

Climbing to Boulder RidgeThe path climbs through dense forest to the park boundary, follows it briefly, then continues…

The path climbs through dense forest to the park boundary, follows it briefly, then continues south to the ridge meadow. The small meadow is the endpoint; it is not a broad overlook. Turn around there and retrace the same route to the dam.
