Upper Kintla Lake via Boulder Pass Trail

From the western trailhead, the route follows the north shore of long, narrow Kintla Lake to its head. This section is described as mostly level with a few hills, and Kinnerly Peak comes into view as you approach the far end. The separate Kintla Lake Head day hike ends here, near the lower lake's backcountry campground; it does not continue to Upper Kintla.

Beyond the lower lake head, the trail runs about 2.7 miles through partly forested country and open meadows toward Upper Kintla. The openings bring views of Kinnerly and Kintla peaks. Published descriptions leave the exact tread and crossings here unclear, so check the current trail report before committing to the full return rather than assuming the gradual profile guarantees easy footing.

The route follows Upper Kintla Lake's north shore to the campground near the lake's head. From there, Kinnerly Peak rises from the south shore, with Kintla Glacier and Gardner Point farther off. The lakeside campground is the day's destination; turn back here. Kintla Creek and the steep climb toward Boulder Pass come just beyond it and belong to the longer through-route. At the Upper Kintla shore, include water in the foreground with Kinnerly Peak across the lake.

Kintla Lake Trailhead is about a quarter mile west of Kintla Lake Campground and is reached from Polebridge through the North Fork roads. Parking capacity and fees were not confirmed. Pets are not allowed on Glacier trails or in the backcountry. A wilderness permit is required if you stay overnight at Upper Kintla Campground. Glacier recommends carrying accessible bear spray in bear country. Early-season trails can be muddy or wet, with high, cold water and lingering snow; snow can return in fall, so check current road and trail conditions before the remote drive.
