Highline Trail from Logan Pass to The Loop

The walk starts at Logan Pass, where the Highline Trail leaves Going-to-the-Sun Road opposite the Continental Divide sign. It soon crosses a narrow ledge cut into the Garden Wall, with a hand cable, then runs north along the mountainside, over a saddle by Haystack Butte, to the historic Granite Park Chalet. From there the Granite Park Trail drops through forest burned in 2003 to The Loop, a hairpin bend on Going-to-the-Sun Road.

It is 11.7 miles (18.9 km) one way with 1,060 feet (323 m) of climbing and 3,410 feet (1,038 m) of descent; allow about 6½ hours. The grade is Hard: a long day on an exposed trail, ending with a long, steep descent.

Much of the trail is exposed, with steep drop-offs and no shelter from storms. This is grizzly country: carry bear spray, hike in a group and make noise; the park closes the trail at short notice for bear activity, as it did in August 2026. Snow keeps it closed into early summer. The alpine section of Going-to-the-Sun Road usually closes for the winter by the third Monday in October, or sooner if it snows.

From July 1 to September 7, 2026, a Logan Pass shuttle ($1 a seat on Recreation.gov) linked The Loop with Logan Pass; otherwise you need a second car or a lift. Parking at The Loop is limited.
