Avalanche Lake Hike in Glacier National Park: Everything You Need to Know Before You Go

There’s something about the Avalanche Lake hike in Glacier National Park that just sticks with you.

Maybe it’s the feeling of weaving through an ancient cedar forest and hearing the rush of glacial water beside you. Or the moment you step out of the trees and the calm, turquoise lake, surrounded by steep cliffs and waterfalls trickling from the melting snowfields above. No photo ever really captures it. And honestly? I’m kind of glad. It means you have to go see it for yourself.

If you’re planning a visit to Glacier National Park, Avalanche Lake is one of those must-do hikes, especially if you’re a first-timer. Here’s what you need to know before lacing up your hiking shoes.

🚘 How to Get to Avalanche Lake Trailhead and Where to Park

Let’s start with the not-so-fun part: the parking lot fills fast. Avalanche Lake is accessed from the Trail of the Cedars trailhead along Going-to-the-Sun Road, one of the most popular stops in the park. If you roll in after 8:00 a.m. in peak season (July–August), you’ll probably be out of luck.

Heads up: You’ll need a vehicle reservation for the Going-to-the-Sun Road corridor if you plan to enter the park at or after 6 a.m. So if you’re shooting for that early arrival around 7:00, make sure you’ve secured a reservation for the day. No res? No problem—just get there before 6:00 a.m. and you can drive in without one. Yes, that might mean a pre-dawn wakeup call, but the reward is a quiet trail and sunrise views over the lake.

Pro tip: Take the free park shuttle if it’s running, or beat the clock and arrive super early. You’ll avoid the crowds and the reservation requirement.

🥾 Avalanche Lake Trail Details: Distance, Difficulty, and Time

Distance: 4.6 miles round-trip (give or take)
Elevation gain: About 730-760 feet
Time: 2 to 3 hours for most people

The trail starts off paved and flat as it loops through towering cedars—perfect for strollers and wheelchairs (at least the first part). Once you cross the bridge and start climbing, it turns into a classic forest trail with some roots and rocks, but nothing too gnarly. It’s family-friendly, but wear decent shoes and bring water. You’ll earn your lunch, but you won’t be gasping for air either.

🎒 What to Pack for the Avalanche Lake Hike

Keep it light but smart:

Water (you’ll sweat more than you think)
Snacks or a picnic (there are flat rocks to sit on at the lake)
Bear spray (always in Glacier)
Bug spray (especially early summer)
A rain jacket or windbreaker (the weather changes fast here)

If you’re hiking with kids, this is a great trail to bring a toddler backpack carrier—there are fun spots to explore but enough uphill that little legs may tire. Just take breaks and take your time!

🐻 Bear Safety on the Avalanche Lake Trail

Yes, this is bear country. No, you don’t need to be afraid—but you do need to be prepared. Make noise on the trail (talk, sing, clap occasionally), carry bear spray, and know how to use it. We’ve seen everything from deer to marmots on this trail. Just give all wildlife plenty of space and don’t feed anything.

📸 Best Avalanche Lake Viewpoints and Photo Tips

When you get to the lake, don’t just stop at the first clearing. Walk a little farther along the shoreline trail to the left—you’ll find quieter spots and a better view of the waterfalls. Sometimes there are small log rafts floating near the shore that kids (and brave adults) like to walk on for a photo op. Just be careful—they’re slick!
