With hairpin turns climbing past granite peaks to Logan Pass and beyond, the soaring Going-to-the-Sun Road is an engineering marvel and a 50-mile adventure for travellers.

Open only a few months annually, usually after snowplows have cleared the road in mid-June, this scenic drive should be one of your first activities after arrival. From Logan Pass (6,646ft) at the top of the road, the Highline Trail drops nearly 12 miles past purple and yellow wildflowers, snow-dappled peaks, a gritty glacier and, quite possibly, roaming grizzlies. Catch the shuttle at The Loop shuttle stop for a ride back to the pass. As for the park’s namesake glaciers, the number has dwindled from eighty or so in 1850 to 26 in 2015.
