About this Trail

**This hike is currently closed due to the 2017 Kenow Wildfire. Parks Canada is working hard to get this reopened we will keep you posted ! For hikes that are open you can also check the Parks Canada website **

You don’t have to be a seasoned hiker to take on the journey that is Carthew-Alderson Trail, but you’ll want to be physically and mentally prepared for the excursion. From end to end, Carthew-Alderson is 20 km of breathtaking vistas, challenging switchbacks, cascading waterfalls, lush forests and a series of mountain lakes – each seemingly more deeply blue and pristine than the next. It’s an 8-hour adventure all-in (unless you choose to stay overnight at one of the trailside campsites) one of Waterton’s famous “Triple Crown” hiking trails, and every inch is worth the effort it takes to get there.

You can begin at the western end of the trail near Cameron Lake, or start at Waterton village where the trail kicks off at the base of Cameron Falls. Shuttle rides are offered back and forth from either location once a day in the morning. Please check Waterton Outdoor Adventures for more information on pick up locations and times.

Along the way prepare to be awestruck. The trail reveals some of the most remote territory in all of Waterton Lakes National Park – a virtual moving picture of colour and sound unlike any you’ve encountered before. You’ll gain (or lose, depending on which end of the trail you start) 650 meters (2,132 feet) of elevation on the hike, and the vantage points across the miles are astounding to say the least. Five remote mountain lakes, only accessible on foot, are encountered on this trail, and at the summit, you’ll get a bird’s eye view of Waterton Lake and village with majestic Vimy Peak in the distance.

We hiked this with our 14 and 11 year old children this past July. It was an amazing hike that we all enjoyed. The scenery was unbelievable and varied. Highly recommend it.
