Trail guide
This is a 13.2-mile out-and-back from the Kintla Lake trailhead to the head of the lake and a backcountry campground, following the Boulder Pass Trail beside the water. The route is 6.6 miles one way. Allow about six to seven hours for the full return trip, including time to stop. Expect rolling hills rather than a flat shoreline stroll; this is a remote, full-day walk for hikers comfortable with the long drive and distance.
The route turns around at Kintla Lake Head, before the much longer Boulder Pass route leaves the lake and climbs toward the pass. The trail is an earth tread through forest, with the lake and mountain views opening between the trees.
The path follows the lake through a forested slope. Openings frame Long Knife and Parke peaks across the water, while the canopy gives much of the walk a shaded feel. In early summer, the filtered light catches glacier lilies, wild roses and mariposa lilies along the trail. The hills are rolling, so the work comes from covering the distance rather than one sustained climb.
At the far end, the lakehead backcountry campground marks the destination. Kinnerly Peak becomes prominent across the water. Beyond the lakehead, the through-route crosses Kintla Creek and climbs switchbacks toward Boulder Pass; that demanding extension is a separate, much longer hike and is not included in the 13.2 miles here.
A faint junction with the Kintla Trail appears about 3.7 miles from the campground access. Turning around there makes a roughly 7.7-mile out-and-back from the signed trailhead, giving you the shaded shore and lake views without continuing to the head. The Kintla Trail is a different backcountry route; watch for the junction and stay on the lakeshore line if you mean to reach Kintla Lake Head.
The signed Boulder Pass trail access is 0.25 miles west of Kintla Lake Campground. Hiker and backpacker parking is before the campground; campsite spaces are reserved for campers. Reaching this part of the North Fork involves a long gravel-road drive from Polebridge, so build in time for the approach. Polebridge Mercantile is a separate stop, not a trailhead facility; its bakery is known for huckleberry bear claws.
Pets are not allowed on Glacier trails. This is bear country: make noise as you walk, hike with others when possible, and carry bear spray where you can reach it.
