Essential Travel Tips
Book your vehicle reservations for Going-to-the-Sun Road WELL in advance, especially if you're visiting between late May and early September. These timed entry tickets are essential for driving your personal vehicle on the most iconic road, and they sell out within minutes of release on Recreation.gov. If you miss out, consider using the park's free shuttle system, but be prepared for crowds and limited seating.
Pack layers, layers, and more layers! The weather in Glacier can change dramatically in a single day, even in summer. Think moisture-wicking base layers, a fleece or puffy jacket, and a waterproof/windproof outer shell. You'll be grateful you have them whether you're hiking to a chilly alpine lake or caught in an unexpected afternoon shower.
Be bear aware, always. Carry bear spray, know how to use it, and make noise while hiking, especially in areas with limited visibility. Store all food and scented items properly in bear-resistant containers or your vehicle, and never leave food unattended. Remember, you're in their home, so respecting their space is crucial for everyone's safety.
Bring cash for smaller vendors and tips, as cell service can be spotty in many areas, making card readers unreliable. While most park entrance fees and larger lodges accept cards, you might find charming roadside stands or smaller gift shops that prefer or only accept cash. It's also a good idea to have some on hand for unexpected opportunities.
Embrace the 'Leave No Trace' principles wholeheartedly. This means packing out everything you pack in, staying on marked trails, and respecting wildlife from a distance. The park's pristine beauty is a treasure, and by minimizing our impact, we help preserve it for future generations and the native ecosystems.
Pack plenty of your own snacks and lunches, especially for full-day hikes. Dining options within the park are limited and can be expensive, with long waits during peak season. Having your own provisions means you can enjoy a picnic with a million-dollar view without the hassle or cost.
💡 Travel Tip: If you're planning your trip, it's worth checking flight prices on Trip.com before you decide.

Getting Around Glacier National Park, USA
Going-to-the-Sun Road Shuttle
This free shuttle service is a lifesaver for navigating the iconic Going-to-the-Sun Road, especially during peak season when private vehicle access is restricted. It connects major trailheads and visitor centers, allowing you to hop on and off at your leisure.
Private Vehicle (with reservations)
Driving your own car offers the most flexibility, but be aware that vehicle reservations are now required to enter certain areas of the park during peak season. This system aims to reduce congestion and improve the visitor experience.
Biking the Going-to-the-Sun Road
For the truly adventurous and fit, biking offers an unparalleled way to experience the Going-to-the-Sun Road, especially before it fully opens to vehicles or after it closes. You'll have the road largely to yourself and can stop whenever you please.
Amtrak (to nearby towns)
While not directly within the park, Amtrak's Empire Builder line stops in Whitefish and West Glacier, offering a scenic and relaxing way to arrive in the region. From these towns, you can arrange further transportation.
Local Taxis and Ride-Sharing (limited)
Limited taxi services operate in the gateway towns surrounding Glacier, and ride-sharing options are scarce within the park itself. These are best for short trips to and from lodging or trailheads if you're not using the park shuttle.

Frequently Asked Questions
When is the absolute best time to visit Glacier National Park to see the iconic Going-to-the-Sun Road and avoid the worst crowds?
For the full Going-to-the-Sun Road experience with fewer crowds, aim for late July or early August. While it's peak season, the road is usually fully open by then, and the wildflowers are stunning. If you can swing it, visiting mid-week rather than on a weekend will make a noticeable difference in traffic and parking.
I'm planning a trip in early October. Will Going-to-the-Sun Road be open, and what should I expect?
Honestly, early October is a gamble for the Going-to-the-Sun Road. It typically closes sometime in the first two weeks of October due to snow, so always check the park's official website for current conditions before you go. Even if it's closed, the lower elevation areas like Lake McDonald Lodge and Many Glacier are still incredibly beautiful, and you might catch some gorgeous fall colors.
What's the deal with vehicle reservations for Going-to-the-Sun Road? Do I really need one?
Yes, you absolutely need a vehicle reservation for the Going-to-the-Sun Road corridor during the peak season (typically May through September). This isn't just a suggestion; it's a requirement to drive the road during certain hours. Book these well in advance on Recreation.gov, as they sell out incredibly fast – think of it like getting concert tickets!
Besides the famous spots, are there any less crowded, equally stunning hikes or areas within Glacier I should consider?
Absolutely! For a less crowded but equally breathtaking experience, head to the Many Glacier area, especially if you can snag a boat tour across Swiftcurrent Lake and Josephine Lake. The hike to Grinnell Glacier Overlook from there is challenging but offers unparalleled views. Another gem is the North Fork area, which requires a high-clearance vehicle but rewards you with remote beauty and fewer people.
I'm concerned about wildlife, especially bears. What are the essential safety tips I need to know?
Bear spray is non-negotiable here; carry it, know how to use it, and keep it accessible at all times, especially on trails. Make noise while hiking – talk, sing, clap – to avoid surprising bears. Stick to established trails, never feed wildlife, and always maintain a safe distance. Remember, you're in their home, so respect their space.
What's the best way to get around the park if I don't want to drive everywhere or deal with parking?
The park's free shuttle system is a lifesaver, especially for accessing the Going-to-the-Sun Road corridor. It runs frequently and stops at key trailheads and viewpoints, allowing you to hop on and off. This is the best way to avoid the parking headaches at popular spots like Logan Pass and Avalanche Lake. Just be aware of the shuttle's operating schedule.
