How long is the Going-to-the-Sun Road?

Going-to-the-Sun Road is THE highlight of Glacier National Park, Montana. Seriously, this 50-mile stretch nestled way up in the Rockies is an engineering masterpiece and arguably one of the most scenic drives on the planet.

Starting in West Glacier and winding all the way to St. Mary, this "crown jewel of scenic drives" is entirely paved, but don't let that fool you – it's narrow! Think two lanes, hairpin turns, and seriously stunning views paired with twisty sections and cliff edges.

Heads up: oversized vehicles aren't allowed in certain sections. Anything wider than 8 feet is a no-go between Avalanche Campground and Rising Sun picnic area. Also, taller vehicles (over 10 feet) might scrape the rocks heading west from Logan Pass.

Construction started way back in 1921, and it finally opened in 1933. This is the only road that crosses the entire park, so it's a must-do! Budget at least 2 hours without stops, but trust me, you'll WANT to stop.

You'll cruise through incredible landscapes, from glacial lakes and forests in the valleys to alpine tundra up at the pass. The views change dramatically depending on which way you're driving.

The road's usually open from mid-June to mid-October, but snow can shut things down early. They get up to 80 feet of snow at Logan Pass! Speaking of Logan Pass, that's the highest point at 6,646 feet.

One major heads up: During peak summer (usually late May to early September), you NEED a timed entry reservation to drive Going-to-the-Sun Road. You'll have to snag a permit in advance through the National Park Service. No permit, no entry during restricted times. Always check the park's official website for the latest details.
