Hiking in Waterton Lakes National Park
Waterton Lakes National Park, tucked into the southwest corner of Alberta where the Rocky Mountains meet the prairies, is often called a walking park for good reason. Its trail network ranges from gentle strolls to demanding alpine treks, all set against a backdrop where international borders converge and mountains rise dramatically from grassland. Whether you have an hour or a full day, there's a trail here suited to your pace and ambition. This guide walks through the park's signature hikes, from the legendary Triple Crown challenge to easy family-friendly walks, plus a few practical tips for making the most of your time on the trail.
Key Takeaways:
The Triple Crown of Waterton (Crypt Lake, Akamina Ridge, and Carthew-Alderson) is a summer-long challenge for ambitious hikers.
Carthew-Alderson is considered the most visually rewarding hike in the park, passing four alpine lakes over a 20.1 km one-way route.
Crypt Lake requires a boat shuttle and features waterfalls, a tunnel through the mountain, and a cable-assisted cliff traverse.
Easier options like Cameron Lakeshore, Blakiston Falls, and Bear's Hump offer big rewards with minimal elevation gain.
Wildflower season adds extra colour to trails throughout the park.
Pack for wind and know your limits before setting out.
The Triple Crown of Waterton
For hikers looking for a season-long goal, the Triple Crown of Waterton challenge combines three of the park's most demanding and celebrated trails and all three continental divides: Crypt Lake, Akamina Ridge, and Carthew-Alderson. Complete all three in one summer and you'll earn an exclusive Triple Crown pin, a spot on the Glory Board, and bragging rights as a certified mountaineer. Sign-up happens at Pizza of Waterton, where hikers check in before and after each trail.
Carthew-Alderson Trail
A personal favourite of the Corner Mountain Inn & Wellness Centre’s innkeeper, the Carthew-Alderson trail is a one-way, high-alpine journey that touches nearly every type of terrain and vegetation the park has to offer, along with four alpine lakes. At 20.1 km (12.5 miles) with 650 m (2,132 ft) of elevation gain, it's rated difficult and typically takes six to eight hours. Start by catching a shuttle from the Tamarack to the trailhead at Cameron Lake. The path climbs steadily through switchbacks to Summit Lake, then continues through forest before breaking into an avalanche path bursting with wildflowers. From there, the trail follows the basin's cirque and climbs a loose shale slope, zigzagging to the ridge for sweeping panoramic views. Many hikers stop for a picnic lunch on the eastern point of Carthew Mountain, where the 360-degree views are hard to beat. The descent winds toward Carthew Lakes across a shale slope (don't be surprised to find snow here even in August) before reaching the gem-coloured Alderson Lake, a popular spot to cool tired feet. The trail finishes at Cameron Falls in the townsite, delivering both a physical challenge and a strong sense of accomplishment.
Akamina Ridge Hike
Akamina Ridge is another demanding but rewarding route, passing two alpine lakes and offering a long ridge walk with unobstructed 360-degree views. The trailhead sits along the Akamina Parkway and shares its start with the trails to Forum and Wall Lakes, so hikers can choose their preferred loop. The full hike covers 18.2 km (11.3 miles) round trip with 905 m (2,970 ft) of elevation gain, rated difficult, and generally takes about eight hours.
Crypt Lake Hike
National Geographic once named Crypt Lake one of the world's 20 most thrilling trails, and it's easy to see why. The adventure begins with a 15-minute boat ride across Upper Waterton Lake via Waterton Shoreline Cruise Co., dropping hikers at Crypt Landing. From there, the trail passes four dramatic waterfalls before reaching the hike's signature features: a steel ladder, a 60-foot tunnel carved through the mountain, and a short, cable-assisted manoeuvre around a cliff. The reward at the end is the stunning Crypt Lake itself. The full round trip covers 17.2 km (10.7 miles) with 700 m (2,300 ft) of elevation gain, rated difficult, and takes five to eight hours.
Easier Hikes for All Abilities
Not every great Waterton hike requires all-day stamina.
Cameron Lakeshore is a 3 km (1.9 mi) round-trip stroll with minimal elevation gain, taking about an hour. It offers views down the lake, where grizzly bears are frequently spotted, and touches the point where Alberta, British Columbia, and Montana meet.
Blakiston Falls is an even shorter option at 2 km (1.2 mi) round trip, leading to a viewpoint with several walkways for a close look at the thundering falls. The trail is accessible for hikers of all ages and abilities.
For something in between, the Upper Rowe Lakes Trail runs 12.8 km (8 miles) with 575 m (1,886 ft) of elevation gain, rated moderate, passing through beargrass-filled meadows to a lake worth a dip if you're brave.
Finally, Bear's Hump is one of the park's most popular short hikes: a steep but quick 2.8 km (1.8 mile) climb rewarded with one of the most iconic views in the valley, best enjoyed at sunrise.
Photo-Worthy Spots
Several locations throughout the park are especially picture-perfect and worth building extra time into your itinerary:
Bertha Lake (a 10.4 km round trip past Bertha Point and Lower Bertha Falls)
The famous Cameron Falls in the townsite
The still waters found throughout the park
Seasonal wildflowers especially Indian Paintbrush
Hiking Tips
Modern conveniences have made it easy to feel distanced from the natural world. We rarely go without heat, refrigeration, or shelter from the elements. When you do head outdoors, it's worth remembering that tools like bug spray, GPS, and rain gear give a sense of control that nature doesn't always honour. Have a plan and know your limits.
A few practical notes:
If your boots have three grommets, lace them lowest, highest, middle, then lowest again to secure your heel and keep your toes from sliding forward.
The Corner Mountain Inn and Wellness Centre offers a bagged lunch for early hikers so you can make sure to properly fuel your body.
Pack a windproof layer no matter the season; The mountain weather can change quickly. Waterton is one of the windiest places in Canada, with average daily winds around 30 km/hr and gusts that can exceed 100 km/hr in fall and winter.
