Biking in Glacier National Park Before Roads Open to Cars
Don’t get me wrong – I love all seasons of Glacier National Park, but there’s nothing like biking on Going-to-the-Sun Road. This unique experience is available for a limited time each spring, before the park roads open to vehicles. It is peaceful, scenic, and an unforgettable way to explore Glacier landscapes.
Why Bike in Glacier National Park Before the Roads Open to Vehicles?
1. Peace and Solitude in Glacier National Park
If you’re looking for solitude in Glacier National Park, this is the time you will find it! Biking before the roads open means you get to experience this majestic place without the noise and congestion of cars. It’s just you, the mountains, and the wildlife in their natural habitat. Yes, there are other bicyclists and people, but it’s so much less stress and fun just to explore nature with others.
2. Car-Free Scenic Rides
Going-to-the-Sun Road, one of the most famous scenic drives in the U.S., remains closed to vehicles until late June or early July. But during the spring thaw, it’s open for bicycles and walking. You can ride along this stunning route—without any traffic—to take in panoramic views. Depending on the weather and time of year, you may not be able to bike up the entire GTSR. Many years, they do not let people past the Loop, as there is risk (and previous incidents) of avalanches in the spring.

3. Prime Wildlife Viewing Opportunities
In the early spring, wildlife is often more active as they emerge from winter hibernation. On a bike, you can cover more ground and spot creatures like mountain goats, elk, bears, and deer. The quiet nature of biking increases your chances of seeing animals up close, without disturbing their habitats. Bears seem to be more common near Avalanche Campground area, as I’ve seen them multiple times now while biking in that area.

4. Spring Wildflower Blooms
Late spring to early summer is the time when wildflowers start to blanket the valleys of Glacier National Park. If you bike before the roads open to vehicles, you get to enjoy these vibrant wildflower fields in solitude. The views along the Bowman Lake, Lake McDonald, and St. Mary Lake are breathtaking.
Top Routes to Bike in Glacier National Park Before the Roads Open to Cars
1. Going-to-the-Sun Road
Arguably the most famous bike route in Glacier National Park, Going-to-the-Sun Road offers 50 miles of awe-inspiring views. Depending on the time of you, you can start at Apgar Village and ride up through McDonald Creek, past lush forests, to Lake McDonald Lodge. Even further, you’ll reach Avalanche Campground, the Loop, and Logan Pass, the highest point in the road.
Most years, we start at Lake McDonald Lodge, ride to the Loop, and then back. If you are not in shape, I highly recommend renting (or buying) an electric assist bicycle. Just make sure your battery is fully charged, and you understand the mechanics of your bike.

2. Lake McDonald Valley
The Lake McDonald Valley is another beautiful area to explore by bike. This route offers panoramic views of Lake McDonald with its sparkling waters and stunning mountain reflections. As you ride along the water’s edge, you’ll pass through dense forests, open meadows, and have plenty of opportunities to spot wildlife.
3. Many Glacier Road
For those seeking a more challenging ride, Many Glacier Road is an excellent choice. The route takes you through a pristine valley with breathtaking views of the surrounding glaciers and waterfalls. You can even extend your ride to Swiftcurrent Lake (if construction allows), a beautiful spot for a picnic or a break in nature.
Tips for Biking in Glacier National Park Before the Roads Open to Vehicles
1. Check the Road Status
While many roads in the park are typically closed until mid-June, check the Glacier National Park website for real-time updates on road conditions. Snow and weather can sometimes cause delays in road openings, so be sure to confirm before you go.
2. Bring the Right Gear
Spring weather in Glacier National Park can be unpredictable, with snowstorms, rain, and sunshine all occurring in the same day. Even if the weather is warmer (50s or above), the ride back down is COLD! WEAR GLOVES! Make sure to pack layers, including a waterproof jacket, gloves, and a helmet. Having the right gear ensures you stay warm and safe while cycling through the park’s stunning landscapes.
If you are not in shape, I highly recommend renting (or buying) an electric assist bicycle. Just make sure your battery is fully charged, and you understand the mechanics of your bike.
3. Watch for Snow and Ice
Some parts of the park, especially at higher elevations like Logan Pass, may still have snow and ice, even in late spring. Be prepared for tricky conditions on the trails and use caution when navigating these areas.
4. Plan for Early Mornings
Mornings in Glacier are magical, and biking in the early hours allows you to experience the park at its quietest and most serene. Plus, you’ll have more daylight hours to explore, especially if you’re riding the entire Going-to-the-Sun Road. Again, mornings are cold… wear/pack the right gear.
5. Respect Wildlife
When biking in Glacier National Park, be sure to keep your distance from wildlife. Bears, moose, and other animals are more active in the spring, and it’s essential to give them space. Follow all park guidelines regarding wildlife safety and always be alert.
