Why go
Going-to-the-Sun Road crosses Glacier National Park for 50 miles, from the shore of Lake McDonald over the Continental Divide at Logan Pass and down to St. Mary. Before it opens to cars each summer, the park lets people walk and ride beyond the vehicle closure, so for a few weeks cyclists can climb between walls of plowed snow with the road almost to themselves.
The route
The classic ride climbs from the west. From the vehicle closure at Lake McDonald Lodge it is 21 miles to Logan Pass, and from Avalanche Creek 15.5 miles with 3,208 feet of climbing. The road follows McDonald Creek, passes the West Tunnel and the hairpin at The Loop, then traverses the cliffs of the Garden Wall by Big Bend to the pass. From the east, the climb from Rising Sun is 11.5 miles and 2,313 feet, past St. Mary Falls trailhead and Siyeh Bend.
When to go
Spring riding runs from when plowing begins until the road opens to vehicles, which has usually happened by early July. In 2026 the full road was open to bicycles only from 18 to 21 June, before cars arrived on 22 June. After that, riding is best early in the morning. The alpine section usually closes to cars around the third Monday of October, sooner if snow comes.
Getting there
Glacier Park International Airport, near Kalispell, is about 30 miles from the West Entrance, and Amtrak stops year round at West Glacier. Most riders start from Apgar. In 2026 the park ran no hiker/biker shuttle, though permitted local companies rented bikes and offered transport.
Permits and booking
Entry by bike costs $20 per person for seven days ($15 from November to April), and non-US residents aged 16 and over pay $100 more. No vehicle reservation was needed in 2026. In spring, closures for road crews apply Monday to Thursday and avalanche closures apply at all times; passing them can bring a fine of up to $5,000. Once the road opens to cars, until 27 September, bikes may not ride eastbound from Apgar to Logan Pass between noon and 6 pm, or westbound between 3 pm and 6 pm.
How hard it is
The climb is steady, with grades around 6 percent, but it is long and reaches high, cold ground. There are no bike lanes or shoulders. In summer you share a narrow road with heavy two-way traffic, ride single file, and pull over when four or more cars stack up behind you. Lights or reflectors are required between sunset and sunrise.
Where to sleep
Riders base themselves at West Glacier, Apgar or Lake McDonald Lodge on the west side, or around St. Mary on the east. Apgar, Sprague Creek and Avalanche campgrounds keep shared hiker/biker sites at $8 per person.
Tips
- Carry bear spray, warm layers and a headlamp, since mornings on the pass are cold and services are few in spring.
- Check the hiker/biker closure points, which the park sets each Thursday.
- E-bikes are allowed if the motor is under 750 watts and works only while pedaling.
