Top Things to Do
Sunrise Serenity on Going-to-the-Sun Road
Embark on the iconic Going-to-the-Sun Road before dawn to witness the jagged peaks of Glacier National Park ignite with the first rays of sunlight. The crisp mountain air and the quiet hum of nature are unparalleled, offering a profound connection to the landscape before the crowds gather. Keep an eye out for bighorn sheep grazing on the steep slopes.
Hidden Falls of Avalanche Lake Trail
Hike the moderate Avalanche Lake Trail, a popular but rewarding path that leads to a stunning lake fed by cascading waterfalls tumbling down sheer cliffs. The vibrant turquoise water and the mist rising from the falls create a magical atmosphere. Pack a picnic to enjoy by the lake, and listen for the calls of marmots echoing through the cedar forest.
St. Mary Lake's Wild Goose Island Vista
Pause at the pull-off for Wild Goose Island on St. Mary Lake, a view so iconic it's graced countless postcards. The island, with its lone pine, floats serenely in the impossibly blue water, framed by dramatic mountains. Visit in the late afternoon when the sun casts long shadows, enhancing the dramatic beauty of the scene.
A Taste of Montana at the Snowline Cafe
Venture to the Snowline Cafe in St. Mary for a hearty, locally sourced meal that fuels your adventures. Their huckleberry pie is legendary, a sweet and tangy taste of Montana's wild bounty. It's a perfect spot to refuel after a day of exploring, offering a genuine taste of the region.

Essential Travel Tips
Book your vehicle reservations for Going-to-the-Sun Road well in advance, especially if you're visiting during peak season (late May to early October). These timed entry permits are essential and sell out quickly; check the NPS website for exact dates and times. Without one, you won't be able to drive your personal vehicle on the most iconic road in the park.
Pack layers, and I mean *layers*. The weather in Glacier can change drastically in a single day, from sunny and warm to cold and rainy, even in July. Think a waterproof outer shell, fleece mid-layer, and moisture-wicking base layers – you'll thank yourself when you're hiking at Logan Pass and the wind picks up.
Always carry bear spray and know how to use it when hiking. It's not just a suggestion; it's a vital safety precaution in grizzly country. Keep it accessible on your hip or chest strap, not buried in your backpack, and make noise as you hike to avoid surprising wildlife.
Bring cash for smaller vendors and tips, as cell service can be spotty and not all places accept cards. While most lodges and main visitor centers take cards, you might find charming roadside stands or smaller outfitters that are cash-only. It's also a good idea to have some small bills for park entrance fees if you don't have a pass already.
Respect the park's natural and cultural heritage by staying on marked trails and packing out everything you pack in. This includes food scraps and even fruit peels. Remember, you're a guest in a wild place, and minimizing your impact helps preserve it for future generations and the wildlife that calls it home.
Pack your own lunches and snacks, as dining options within the park are limited and can be pricey. Consider stopping at a grocery store in a gateway town like Whitefish or Columbia Falls before heading in. This saves you time and money, allowing you to enjoy more of the park's stunning scenery without relying on expensive, often crowded, park restaurants.
💡 Travel Tip: If you're planning your trip, it's worth checking flight prices on Trip.com before you decide.

Frequently Asked Questions
When is the absolute best time to visit Glacier National Park to see the iconic Going-to-the-Sun Road without the crowds?
For that sweet spot of open roads and fewer people, aim for the last two weeks of June or the first two weeks of September. Early June can still have snow closures on higher passes, and by late September, the weather gets unpredictable and some services start to wind down. You'll get stunning wildflowers in June and gorgeous fall colors in September, plus a much more relaxed experience than the July/August peak.
I'm planning to hike, but I'm worried about bears. What's the real deal with bear safety in Glacier?
It's smart to be bear aware! Always carry bear spray and know how to use it – it's your best defense. Make noise while hiking, especially around blind corners or in dense brush, so you don't surprise a bear. Most importantly, hike in groups; bears are less likely to approach a group than a solo hiker. Remember, the bears are here to stay, so respecting their space is key to a safe visit.
Is it really necessary to book lodging and vehicle reservations months in advance for Glacier?
Absolutely, and I mean *months* in advance, especially if you want to drive the Going-to-the-Sun Road during peak season. The park implemented a vehicle reservation system to manage traffic, and these slots disappear incredibly fast. For lodging inside the park, think a year out if you want a prime spot. My tip? Book your lodging first, then secure your vehicle reservation once they become available for your dates.
Beyond the famous Lake McDonald and Logan Pass, what's a less crowded but equally stunning area of the park I should explore?
You've got to check out the Many Glacier area on the east side. It's a bit more rugged to get to, but the payoff is immense. Think dramatic peaks, turquoise lakes, and incredible hiking trails like the Grinnell Glacier trail (though that one's popular, the overall area feels less congested). It's a fantastic spot for spotting wildlife too, so keep your eyes peeled!
What's the deal with the park's shuttle system? Is it reliable, or should I plan to drive everywhere?
The park's free shuttle system along the Going-to-the-Sun Road is a lifesaver, especially during peak season when parking is a nightmare. It's quite reliable and runs frequently, allowing you to hop on and off at various trailheads and viewpoints. My advice is to park your car at one of the designated lots (like Apgar or Lake McDonald Lodge) and use the shuttle to explore the road – it lets you actually enjoy the scenery without stressing about parking.
