Backpacking the Medicine Grizzly Lake Trail in Glacier National Park

The Medicine Grizzly Lake trail is an underrated, relatively quiet hike in Glacier National Park. You’ll have views of alpine meadows, towering peaks, cascading waterfalls, and the lake! At about 12 miles (19 km) round trip, it’s perfect for a long day hike, or for a short backpacking trip – and with only about 900 feet (274 m) of elevation gain, it’s a great beginner backpacking trip too.

This guide will tell you about hiking or backpacking the Medicine Grizzly Lake trail in Glacier National Park, and everything you need to know for the adventure!

Leave No Trace on the Medicine Grizzly Lake Trail

Anytime you’re outdoors, it’s essential that you practice Leave No Trace (LNT). LNT is a set of seven principles that help us understand our impact on the outdoors – because while we usually have good intentions, the environment is more fragile than we think, and one snap-second decision can cause damage to the environment that will take the earth years, even decades to repair. This is a pretty popular hike, so it’s super important to make sure to prevent damage!

Leave No Trace means enjoying the outdoors without disrupting nature, as much as it’s possible to do so. Here are the 7 principles of LNT, and how they apply when you hike the Medicine Grizzly Lake Trail!

• Plan ahead and prepare – read this guide, know what to expect, and bring water. Make sure to have a map handy! I use All Trails for maps.
• Travel and camp on durable surfaces – stay on the trail and don’t take any shortcuts, as this causes erosion, kills plant life, and damages trails.
• Dispose of waste properly – don’t leave trash, or anything else, behind. Pack it out!
• Leave what you find – I know it can be tempting to take a cool rock or leaf, but leave these things where they belong! Animals often use these, and if everyone takes one, the trail won’t be as pretty.
• Minimize campfire impacts – campfires are not allowed on the trail.
• Respect wildlife – don’t approach wild animals, and never feed them. There are often bear and moose sightings on this trail, so be careful, make noise as you hike, and use the bear hang at camp!
• Be considerate of other visitors – yield to uphill hikers, and be respectful – no speakers or loud music.

The Best Time to Hike the Medicine Grizzly Lake Trail

The best time to hike the Medicine Grizzly Lake Trail is usually June through October. Snow can linger into June, and sometimes even July, so definitely make sure to check weather conditions, and read recent AllTrails reviews.

Early summer is great for hiking this trail, because the snowmelt causes wildflowers to bloom, and waterfalls are at their fullest. The weather is also ideal for hiking, as it’s not too hot. I Conditions vary year to year, so it will depend on that! Summer is a popular time to visit Glacier National Park, so you can expect to see more people on the trail.

Early fall is beautiful with the leaves changing, and the weather is cooler! Keep in mind that weather can be less predictable, and snow can start to accumulate at high elevations as soon as October.

Don’t Forget Your Pass!

Because the Medicine Grizzly Lake trail is located in Glacier National Park, you will need a pass to hike. It costs $30 per car, but if you visit national parks often (or at least more than twice a year), I recommend getting an America the Beautiful Pass! It’s an annual pass that will get you into every national park in the country for an entire year, for just $80.

You can purchase either pass on your way into the park, or get an America the Beautiful pass online ahead of time!

How to Get a Permit for Backcountry Camping

Along with the national park pass (which you’ll leave on your dash at the trailhead), you also need a permit to backpack the Medicine Grizzly Lake trail. You don’t need this for day hikes, but it’s a must if you’re staying overnight!

Backcountry camping at Glacier National Park requires a permit. These can be really competitive in the summer, so it’s best to get one as early as possible! However, this particular trail isn’t as popular, so you’re likely to be able to get one if you’re flexible with dates, and if you go early in the season. You can get your permit at Recreation.gov. The starting area is St. Mary, and the campsite is called Atlantic Creek.

Note that the campsite isn’t at the lake! It’s about two thirds of the way to the lake, so you can set up camp, drop off your heavy pack, and then keep going to the lake.

After getting the permit online, you will have to pick it up in person from a ranger station. So on your way to the trailhead, or if you’re doing anything else in the park, make sure to make time to do this! If you’re going north from East Glacier Park, the Two Medicine Ranger Station will be closest, and if you’re coming south from Babb, it will be the St. Mary Visitor Center.

When you’re hiking, be sure to carry the permit with you.

What to Bring to Hike the Medicine Grizzly Lake Trail

When you hike the Medicine Grizzly Lake Trail, here’s what you’ll need to bring! To see all of my favorite gear picks, you can check out my Rockporch.

What to Wear to Hike the Medicine Grizzly Trail

• Sun Shirt – this is my favorite thing to wear on hikes, as it provides sun protection while keeping you cool. I like the Mountain Hardware Crater Lake Hoodie, and the REI Sahara Shade Hoodie.
• Hiking Pants – I love the REI Trailmade Shorts and usually hike in them, but if you’re hiking in the cold, or want protection from ticks and bugs, I recommend the Trailmade Pants.
• Layers – it can definitely get chilly as you gain elevation, so a lightweight windbreaker or a fleece is a good idea. For cold weather hikes, a down jacket will keep you warm.
• Hiking Shoes – I prefer hiking in sandals and usually hike in my Chacos, but boots are a good idea if you need more ankle support. I love my Danner boots!
• Socks – I love the Darn Tough socks whether I’m wearing sandals or boots. They’re wool, so they stay warm even when wet, and have some padding that’s extra comfy for long days on the trail!

What to Bring to Day Hike the Medicine Grizzly Lake Trail

• Backpack – you’ll need a backpack for water and snacks. I use a Gregory Nano 18 Hydration Pack for day hikes.
• Water – water is a must, always – and bring more than you think you need. The Gregory backpack comes with a 3L reservoir, which I usually bring, along with a Nalgene water bottle that I put electrolytes in.
• Sunscreen – no matter the time of year, make sure to protect yourself from the sun.
• Headlamp – if you want to get an early start, or stay to watch the sunset, make sure to bring a headlamp. It’s also a good idea to always bring one just in case!
• Trekking Poles – hiking with poles can help with stability, and can be especially helpful if you have knee pain going downhill.

What to Bring to Backpack the Medicine Grizzly Lake Trail

You’ll need a few more things if you’re backpacking!

• Water Filter – There are plenty of options for filtering water along the trail, so you don’t need to pack a ton of water in for this one. I use a Sawyer Squeeze with a CNOC bladder for filtering, and I filter it into this CNOC collapsible water bottle.
• Tent – somewhere to sleep! I love my super light Big Agnes Tiger Wall tent, along with the footprint.
• Sleeping Bag – I actually use a quilt instead of a bag, and I love this one from Enlightened Equipment.
• Sleeping Pad – an essential for a comfy night of sleep! I use this Therm-a-Rest pad.
• Camp Stove – there’s nothing like having a hot meal on the mountain. I use an MSR Pocket Rocket stove, which is incredibly small, along with this GSI Cookset.
• Food Bag – the campsite on this trail has a pole for hanging your food and scented items, so make sure to bring a bag that can be hung up, along with some cord.
• Backpack – I recently got a ULA Circuit, and absolutely love it!
• Headlamp – an essential for seeing after it gets dark.
• Trowel – there’s a toilet at the campsite, and you should use it for all bathroom needs. But, sometimes… shit happens. Bring a trowel just in case.
• Bidet – I like to bring a bidet so that I can carry less toilet paper. I use this one and attach it to my CNOC water bottle.
• Kindle – essential for entertainment at camp!
• Bug Spray – the mosquitos at camp were really brutal, so I definitely recommend bringing some bug spray.
• Bear Spray – it’s highly recommended to carry bear spray on this trail! Hopefully you never need it, but it’s always better to have it.

Directions to the Medicine Grizzly Lake Trailhead

If you’re flying in for your trip, there’s a small airport outside of West Glacier called the Glacier Park International Airport. But, most people fly into the larger airports in Missoula or Great Falls.

Expedia is a good way to find flights and rental cars, I also super recommend signing up for Going (formerly Scott’s Cheap Flights) – they send you amazing deals, so you can find cheap flights to destinations all over the world. The free account is great and totally worth the few minutes it takes to sign up, and I do recommend the premium account too!

If you fly, you can rent a car through Discover Cars or Rental Cars. But, a great alternative to a rental car is a tiny home on wheels! With a camper van, you get a vehicle and a place to sleep, all in one! This is my favorite way to travel, and you can rent a fully decked out van with Escape Campervans. Another option for vans is to use Outdoorsy, which is more like Airbnb for campers – you can rent a van, RV, or trailer from a person in the area.

The trailhead for this hike is called the Cut Bank Trailhead. From Kalispell, you’ll take Highway 2 going north, and get on Highway 89 for a little bit. From Great Falls, you’ll take highway 89 going west. Don’t forget to stop at a ranger station if you’re backpacking and haven’t picked up your permit yet!

You’ll make a left off of Highway 89 onto Cut Bank Creek Road. This is a dirt road with some potholes, but it’s doable for any car. After about 5 miles, you’ll be at the trailhead, just before the campground. There’s a small parking area where you’ll leave your car, and then you’re ready to hike!

Hiking the Medicine Grizzly Lake Trail

Once you’ve parked and are ready to start hiking, here’s what you can expect on the Medicine Grizzly Lake Trail!

Cut Bank Trailhead to Atlantic Creek

The small dirt parking lot at the Cut Bank trailhead is where the hike begins, and the trail is easy to spot. You have some pretty great views already as you walk through the meadow, and then you’ll enter the forest. The trail isn’t very steep – it’s a steady, but mild uphill with a few short climbs throughout. There are a few creeks you’ll have to walk through, but any big crossings have bridges going across, so nothing major! The trail is pretty easy to follow, but keep an eye on your map occasionally, because there are a couple of spots where you can get off trail if you aren’t paying attention. You’ll be walking through the woods, but it opens up pretty often to incredible views of the mountains.

At about 4.1 miles in, you’ll reach the Atlantic Creek Campground! If you’re camping, this is where you’ll stop to unload. The first thing you should do is secure your food and any scented items. There’s a bear hang and a designated cooking area, so make sure not to bring food anywhere outside of this area. I recommend setting up camp and dropping your pack, then continuing on to the lake!

Atlantic Creek to Medicine Grizzly Lake

From the campground, it’s just a little over 2 miles to the lake. You’ll walk out to a meadow, and soon, you’ll see the mountains that surround the lake in front of you. Once you get to the lake, there’s a trail that goes to the right and keeps going – I highly recommend taking it! It’s overgrown in some places, but keep going to the end, and you’ll see another waterfall that wasn’t visible before, and you’ll have an amazing view of the lake. It’s worth it!

Back to the Trailhead

You’ll head back the way you came. If you’re camping, you’ll stop at Atlantic Creek and spend the night there, then keep going to the trailhead in the morning. The way back is pretty easy, with a steady decline until you get to the trailhead!

Where to Stay Near the Medicine Grizzly Lake Trail

The Atlantic Creek Campground is along the trail, but if this hike is part of a trip to Glacier National Park, there are some great places to stay nearby!

camping Near Glacier National Park

There are campsites in the park, but I recommend staying just outside of it, because it’ll be quieter, and easier to find a spot. I recommend using The Dyrt – it’s the best way to find campsites. You can use the free version to find campsites, but with The Dyrt Pro you’ll also be able to see the boundaries of national forest land just outside of the park. You can stay in one of the paid campsites, or, in the national forest, you can camp just about anywhere for free! You can try The Dyrt before you commit, so click here for a free trial.
