Are you looking for a spectacular hike and easy scramble near Lake Louise? Devil’s Thumb is an awe-inspiring, challenging route in Banff National Park that delivers big rewards for the effort. From the summit, you’re treated to iconic views over both Lake Agnes and Lake Louise — just be ready for a steep leg-burning climb. If you’re craving an adventure that starts right at Lake Louise, the Devil’s Thumb hike and scramble is a solid pick.
Last Updated: January 2026
If you’ve had a chance to visit Lake Louise, you already know how incredibly scenic this popular place is in Banff National Park. A few years ago, back in July 2021, I woke early and drove out to Lake Louise from my home in Calgary.
I wasn’t planning to complete the Devil’s Thumb hike, but was happy to tag it on after visiting Big Beehive for the first time. As a steep hike and easy scramble, Devil’s Thumb is a lot of fun for Rocky Mountain day trippers. But be warned, Lake Louise tends to be crowded with visitors during peak season (hence why I arrived at 6am). Finding parking can be harder than reaching the summit!

About the Devil’s Thumb Hike (Lake Louise, Banff National Park)
Location: Lake Louise, Banff National Park, Alberta
Distance: 12 km out and back
Difficulty: Difficult
Elevation: 883 metre gain
Time: 3 – 5 hours
Dog-friendly: Yes, but must be kept on a leash.
Features: The Devil’s Thumb hike features spectacular views of Mirror Lake, Lake Agnes, and the world-famous Lake Louise from the summit. You will pass by the Lake Agnes Tea House (with over 100 flavours of loose-leaf tea!) and can plan a nice lunch stop. As a side trip, you can head over to Big Beehive, Little Beehive, or Plain of Six Glaciers for a longer trek.
Note: Devil’s Thumb involves steep hiking and scrambling (using hands to climb) to reach the summit. If you’re not comfortable with scrambles, you may want to pass on this one and enjoy the Big Beehive hike instead.
Finding the Devil’s Thumb Trailhead at Lake Louise
The Devil’s Thumb hike begins along Lake Agnes Trail from Lake Louise. During peak season (May to October), it’s not uncommon for the Lake Louise parking lots to fill up, requiring visitors to use this Park and Ride service about 10km away. If you want to avoid parking hassles, this shuttle brings visitors straight to the Lake Louise entrance.
On Canada Day, I chose to leave Calgary early in the morning and arrived at Lake Louise by 6am. Surprisingly (or not so much), the main parking lot was nearly half full! I’ve heard that both parking lots can reach capacity as early as 7 o’clock. It’s not hard to find the trailhead from the parking area. Head toward Lake Louise and follow signs for Lake Agnes Tea House, on the west side of the lake. This is where the fun begins.
Devil’s Thumb Hike: Lake Louise to Lake Agnes Tea House
After starting the Lake Agnes Trail, continue up through the forest for 3.4 km to the Lake Agnes Tea House. You hike along a gentle grade passing by Mirror Lake, dubbed “Goat’s Looking Glass” by the Stoney Nakoda First Nation. Legend has it that mountain goats used this reflective lake to comb their beards. If you look up, you can see Big Beehive towering above the lake (can you tell how it got its name?).
This section is much easier than what’s ahead. Continue toward Lake Agnes and check out the waterfall before heading up a set of wooden stairs to the tea house. It’s important to note that, even if you’re only hiking to Lake Agnes, bring essential hiking gear. On this very hot day, I drank most of my two-litre water reservoir by the end.
Side Trail to Big Beehive (Optional Add-On)
In my humble opinion, you might as well check out Big Beehive if you’re heading to Devil’s Thumb. After all, it’s only around 2 km additional from the junction, and the remarkable views of Lake Louise are worth it. Plus, Big Beehive is a nice spot for a short break or lunch. If you don’t have enough time, Devil’s Thumb will give you better panoramic views.
After reaching the Lake Agnes Tea House, continue along the north shore of Lake Agnes and follow the defined trail to the switchbacks. These switchbacks lead to the junction where you can either go left for Big Beehive or right toward Devil’s Thumb. When I visited, there was a fallen log over the Devil’s Thumb route. Before heading up, I detoured with my new friends, Lucas and Margaux, to the Big Beehive. We were all surprised to witness a marriage proposal (she said yes!). You never know what will happen on the trails, eh?

Devil’s Thumb Scramble to the Summit
I met Lucas and Margaux visiting from Ontario (originally from France) and they had never been to the Canadian Rockies. We spent the day hiking together. After admiring the views from Big Beehive, we retraced our steps back to the junction and continued straight over the fallen tree trunk. You won’t find signs for Devil’s Thumb, and be prepared for some route finding with far fewer people.
If the path to Big Beehive is considered moderate, the Devil’s Thumb hike and scramble is much more challenging. For starters, hiking and scrambling (using hands to climb rocks) may be difficult for some visitors. Further, the route up to the summit is very steep, with small pebbles underfoot. Hiking boots and trekking poles are highly recommended. While the Devil’s Thumb hike and scramble isn’t easy, it’s an incredible day trip if you’re up for it. Be prepared to hike around 15 km and between 4 to 6 hours (including Big Beehive).
Note: Make sure you’re comfortable with the steep and rugged terrain before heading out. We came across one first-timer who couldn’t descend without using my poles (he didn’t bring any…). I guided him slowly down the mountain, showing him the best route and technique to maintain his footing.
What to Bring for the Devil’s Thumb Hike (Banff National Park)
I spend as much time as I can hiking and backpacking, and sometimes cross paths with miserable people who didn’t bring the right gear. Before heading out on any hike, do your research to understand the terrain and be prepared for anything. My day pack is stocked with hiking essentials like water, snacks, a first aid kit, often a water filter, a rain jacket, down jacket, a shelter, a knife, a headlamp, navigation tools, and a few other things. When you’re hiking in Banff, carrying bear spray in a holster is a good idea (but please oh please, forget the bells…. they don’t keep bears away).
I was glad to have my trekking poles and sun protection. As we got closer to the summit, I felt the heat getting to me. I’m fairly prone to dehydration and heat exhaustion… and it was 30+ degrees. I took a short break, while Lucas and Margaux continued on. After a few minutes (and some electrolytes), I was good to go.
Know Before You Go
Park Pass: You’ll need to bring a Parks Canada Discovery Pass or pay the daily rate. The pass can be purchased at the Parks Canada Visitor Centre or online.
Parking: Visitors must also pay a parking fee in the parking lot.
Shuttles: You can book a shuttle through Parks Canada from the Lake Louise Ski Resort or through Roam Transit from Banff. This is a great way to avoid parking hassles.
Toilet: Washrooms with flush toilets are accessible next to the Lake Louise parking lot.
Pets: Dogs are allowed but must stay on a leash. Bring a smell-proof bag to pack out those full poo bags. Consider whether or not your four-legged friend will have fun scrambling to the summit.
Navigation: Pick up a copy of Gem Trek Lake Louise and Yoho map to learn about the many hikes near Lake Louise. Download Devil’s Thumb via Lake Agnes Trail on AllTrails for offline use.
Wildlife: Banff is home to a variety of wild animals, including elk, moose, cougars, wolves, and of course, bears. Please don’t feed or approach wildlife, as they can become habituated and a danger to others. Carry bear spray in a holster and know how and when to use it.
Safety: When you head into the backcountry, you’re responsible for your safety. Exercise caution on the scrambles and cliffs on the summit. Pack a lightweight first aid kit to deal with minor injuries. If you’re hiking solo, leave your trip plan with someone you trust.
