7 Mistakes to Avoid in Glacier National Park

Planning a trip to Glacier National Park? With its dramatic peaks, turquoise lakes, grizzly country, and the iconic Going-to-the-Sun Road, Glacier is a dream destination for nature lovers and outdoor adventurers alike.

But as stunning as it is, visiting Glacier can be surprisingly complicated. From limited access permits to unpredictable weather and remote trailheads, there are plenty of easy-to-make mistakes that can turn your trip into a logistical headache.

That’s why I’ve put together this guide to the 7 most common mistakes people make when planning a trip to Glacier National Park — and how you can avoid them. I’ve navigated the challenges of this park firsthand, and I’m here to help you skip the trial-and-error phase. Whether it’s misjudging how early to book accommodations, not understanding the vehicle reservation system, or showing up unprepared for alpine conditions, this guide will walk you through exactly what not to do—and what to do instead.

This is for anyone who wants to experience Glacier’s wild beauty without the stress—whether you’re here for epic hikes, iconic drives, or just to soak in the scenery.

Let’s make sure you avoid the common pitfalls and enjoy every glacier-carved moment of your adventure.

#1 Not getting a reservation

Rolling up to Glacier National Park thinking you can wing it without a reservation is a huge mistake.  Glacier is extremely popular, especially during the brief and beautiful summer season. The roads became so clogged that the NPS have implemented a time entry reservation system for most sections of the park during the popular summer period.  And those spots typically sell out in seconds.   

So, be sure to book ahead, and secure a vehicle reservation for Going-to-the-Sun Road, the North Fork, or Many Glacier. It’s like having a golden ticket to nature’s wonderland. ,

#2 Not checking the weather

Assuming the weather in Glacier National Park will play nice with your plans can be a mistake. The park’s epic scenery is best enjoyed with clear skies, but the weather can be very unpredictable and changeable. To make the most of those postcard-perfect views, you’ve got to keep an eye on the forecast and be ready to pivot.  

Reservations can make this difficult, but try to build in some adaptability where possible.  

If you’re blessed with blue skies, make a beeline for those panoramic viewpoints and high-elevation hikes where the vistas are unmatched. But if the weather gods roll in the clouds, have a backup plan. That could mean exploring the cedar forests of the Trail of the Cedars or visiting the park’s informative visitor centers. 

#3 Only driving the Going to the Sun Road section

Thinking the Going-to-the-Sun Road is the be-all and end-all of Glacier National Park is another big mistake. Sure, it’s definitely the headliner with its jaw-dropping vistas, but limiting yourself to just this stretch is like going to a buffet and only hitting the salad bar – you’re missing out on a lot of other great stuff!

Branch out to other sections like the Many Glacier area, where you can spot moose and bear, and hike to some seriously stunning spots like Grinnell Glacier.

Over in Two Medicine, you’ll find a quieter slice of paradise with trails leading to gem-like lakes and waterfalls. 

And let’s not forget the North Fork, the less-traveled side of the park that’s perfect for those looking to escape the crowds and find some solitude among the stars.

Each section of Glacier National Park has its own unique flavor and highlights, so spread your wings and explore all the corners of this majestic park. Your inner adventurer will thank you for it.

#4 Staying in your vehicle

Not venturing out into Glacier National Park’s wilds is another mistake – and it’s easy to avoid. Trust me, the real magic happens when you step outside. While Glacier is home to one of the most (justifiably) famous drives in the entire country, this park isn’t just about scenic drives; it’s an outdoor playground begging to be explored.

So if you’re able, leave the comfort of your car and hit the trails – there’s a hike for every level, from the easy strolls around Lake McDonald to the thigh-burning trek up to Iceberg Lake.

If you’re into water adventures, take a boat tour on one of the park’s many glacial lakes. Want a unique view? Hop on a Red Bus tour for some history and stunning sights, or saddle up for a horseback ride through the wilderness.

Whatever you choose, just remember: Glacier National Park is an immersive experience. You can’t fully appreciate its grandeur or whispering pines from behind a windshield.

#5 Underestimating the hikes

While hiking Glacier National Park’s stunning trails is a truly wonderful way to experience, thinking Glacier National Park’s trails are a walk in the park (pun intended) is a mistake. These are the mountains after all, and it’s easy to bite off more than you can chew.

There are easy trails, but before you tackle any of the trails, I really recommend doing your homework. Check out the hike profiles, know the elevation gains, and respect the distance. A trek to Hidden Lake Overlook might sound like a leisurely jaunt, but the elevation can leave you more tired than you anticipated. And remember, the Highline Trail is a high-altitude challenge, not a high-five-and-you’re-done deal.

Pack plenty of water, snacks, and layers, because the weather can turn faster than a plot twist. And most importantly, know your limits. It’s better to enjoy a hike within your comfort zone than to turn your adventure into an unintended survival reality show. 

#6 Not packing for all conditions

Glacier National Park’s weather can be a fickle friend, serving up a smorgasbord of conditions in a single day. You might start your morning with a crisp chill, get a side of midday sunshine, then finish with an evening sprinkle or even a dusting of snow in higher elevations, regardless of the season. 

To truly enjoy the park’s diverse offerings, you need to come dressed for an all-you-can-weather buffet. That means layers, layers, and more layers.  

Throw in a waterproof jacket, some sturdy, breathable hiking boots, and moisture-wicking clothing to keep you comfortable from dawn to dusk. Don’t forget a hat and gloves – they’re the cherry on top of your well-prepared outfit.  

With the right gear, you’ll be ready to embrace whatever comes your way, leaving you free to feast on the park’s natural beauty.

#7 Not Getting Travel Insurance

You should, of course, always have travel insurance, but especially when doing things like hiking.  You just never know what will happen.  Travel insurance also covers things like lost or stolen property, trip cancellation, and emergency repatriation.
