Crypt Lake Trail Waterton Lakes National Park hike Alberta Canada Waterton-Glacier International Peace Park

Crypt Lake Trail is consistently ranked as one of the top hiking trails in the Canada Rockies. To reach the trailhead, you must first take a 15-minute ferry across Upper Waterton Lake. From there it is a 10.8-mile round trip hike to a sparkling turquoise lake cradled by horseshoe-shaped cliffs. You’ll gain 2,300 feet along the way, passing waterfalls, crawling through a tunnel, and clinging to chains bolted along a narrow ledge. At the end of the trail, you can even set foot in another country, the good old U. S. of A. Crypt Lake Trail is an exciting hike to a stunning location – Rocky Mountain perfection!

Canada established Waterton Lakes National Park in 1895, 23 years after the world’s first national park was created in the United States about 300 miles to the south (going by the name of Yellowstone). In 1910, Glacier National Park popped up in Montana just over the border from Waterton Lakes. In the tumultuous year of 1932, the North American neighbor nations linked the two parks to create the world’s first international peace park. It is in this spirit of international friendship that makes its first trip outside the United States for a hike up Crypt Lake Trail. The acclaimed trail could not be a worthier candidate for the milestone.

Start from Waterton Township on the northwest end of Upper Waterton Lake and find the boat launch at the marina for the Waterton Shoreline Cruise Company. Tickets for the Crypt Lake Shuttle Ferry are $32 per person (infants free). Ferries leave at 9:00 a.m. daily from June 3 to October 1, with an additional 8:30 am departure between June 24 and September 3. On the ride to Crypt Landing on the east side of the lake, enjoy fantastic views south toward the United States, and north toward the historic Prince of Whales Hotel situated on a bluff above the lake. There is no drinking water on the boat or along the trail, so pack everything you need before you start. Ferries return to Waterton Township at 3:30 p.m. and 5:30 p.m. (Price and times as of 2023).

If you are an agile hiker and would like a bit more solitude along the trail, try to get to the front of the pack leaving the ferry. Otherwise, you’ll find yourself trapped by slower hikers moving up a single-track trail that rarely offers a passing lane.

There are just two noteworthy junctions along the trail, both with Hell-Roaring Falls Trail. This trail can be used to add a small loop to the start of the hike. The side trail provides glimpses into a canyon carved by a cascading creek, while offering excellent views over Upper Waterton Lake. The first junction with Hell-Roaring Falls Trail comes a quarter mile from the start, breaking off to the right. The second comes at 1.85 miles from Crypt Landing when the trails reunite. Hell-Roaring Falls Trail is steeper than Crypt Lake Trail, so it is preferable to save this route for the descent.

Crypt Lake Trail leaves the landing beneath a lush canopy of spruces and firs. As you make your way up a mile and a half of switchbacks, the forest thins and the shade disappears. You’ll cross an exposed mountainside on the north side of Crypt Valley. Mount Boswell rises like a citadel to the south, capping off an impressive valley view. Pass Twin Falls just over two miles from the start and continue to another lovely waterfall, Burnt Rock Falls, which dangles off the end of short ledge. The biggest and best waterfall lies ahead, but to get there requires interesting maneuvering.

After Burnt Rock Falls, the trail becomes a bit more challenging, climbing higher up the side of the valley. you will be treated to a view of Crypt Falls, a 600-foot streak coursing down a long rock wall. Above the waterfall is the hanging valley that houses Crypt Lake. It is a beautiful sight, but on this hike, things only get more amazing the farther you go.

At 4.5 miles from the start, the trail passes Crypt Lake Campground, a former backpackers retreat that is no longer in operation. Continue half a mile past the campground on what seems like a dead end course toward a sheer cliff. This is the start of the unique and exciting ledge and tunnel section of the hike.

The tunnel along Crypt Lake Trail

Step up an 8-foot metal ladder and into a fortuitous natural tunnel. Crawl, squat, or waddle about 80 feet through the misshapen tube to reach the next challenge, a cable traverse. Hike up a narrow jagged ledge with a good grip on the steel cable bolted to the rock face. The going may appear precarious, but the trail is reassuringly safe while providing a welcome adrenaline rush for those not afraid of heights.

A quarter mile past the chains, the trail passes near the top of Crypt Falls. Take a path off the main trail to look over the brink of the falls. Above the waterfall, the creek pours like magic from a gap in the rocks. In truth, the water is seeping through the ground from Crypt Lake, about a tenth of a mile farther up the trail, cradled in an alpine cirque at an elevation of 6,380 feet.

Crypt Lake is breathtaking. Even if your legs weren’t tired, the beauty would likely stop you in your tracks. The water glistens in a rainbow of colors ranging from emerald green to dark blue and indigo. Purple-tinted gravel scree surrounds the ovular lake adding even more color. Thousand-foot cliffs tower over the lake, leaving a reflection on its mirror-like surface. The imposing wall south of the lake actually lies across the border in the United States. No border patrol is necessary at Crypt Lake though, since only a very skilled climber could get more than a few feet into the US. In late summer, if the ice shelves around the lake have melted, hike down to the south end of the lake to make a brief quixotic entry into the United States. Depending on conditions, it may be possible to hike all the way around the lake for a 30-minute tour.

Pines border the north end of the lake, offering shade for picnickers. While it is tempting to spend all day at Crypt Lake, it is important to manage your time and reserve a few hours for the hike down to the ferry, which departs at 4:00 p.m. and 5:30 p.m. Don’t be late!

On the trek back, turn left at the top of Hell-Roaring Falls Trail to collect new views over a turbulent creek packed with cascades. You’ll get a great perspective of Upper Waterton Lake by returning to Crypt Landing via this route. No permit is required to hike Crypt Lake Trail, but there is an entrance fee for Waterton Lakes National Park as well as a charge to board the Crypt Lake Shuttle. Space on the ferry is limited, so plan ahead. This trail is as exciting and beautiful as they come – guaranteed to leave a lasting impression.
