My favourite hike in Waterton lakes national park. The hike up had variety and nice views. The peak was beautiful. The wind was blowing hard at the peak and made a few people in our party nervous. Hiked it with 4 kids (7,9,11 and 11 yrs). We hiked this before the fires and are very glad we did. This hike is on our top 10 favourite hikes.

Sadly you won't likely be able to hike this in 2018. Its a fabulous hike over amazing terrain so stay tuned.

AMAZING!!! So many things to see. So incredibly tired by the end. I suggest stopping and smelling the roses a lot as there are so many little hidden gem spots to savour on the way down. Also glad we stopped to enjoy it lot as it’s all burned down now :-(

You feel like you are on top of the world. Be prepared for sore knees when going back down.

Had been to Waterton a half dozen times or so and had never heard of this trail, but while talking to another visitor he seemed to have a similar appetite for hikes and recommended this one highly. Without knowing what to expect we were completely blown away. There's so much to see the entire trek and ending at the waterfall back in town was the icing on the cake.

This was our 2nd hike in the Triple Crown Challenge. The day started in the Town of Waterton, were we took a bus to Cameron Lake, then hiked the trail, all the way back to town. This was another one of my favotite hikes in Waterton Lakes National Park. As we gained elevation until we reached Carthew ridge, then it was downhill from there on, awesome scenery.

Absolutely stunning! The best hike I have been on all year. Got rained on a little, but it was still an amazing hike!

The Carthew Alderson is a great trail, if the weather is good. Our hike was during a chilly rainy, snowy, sleety day. The views were greatly impacted by the low ceiling. The hike was still great but I would rather do it on a clear day. The portion from Alderson Lake back to town is not as bad as some say. Be prepared for this hike and wear your layers. We used all of our layers in early September. The GPS was very useful when we got to the top. The very low visibility made it a little tough to stay on the trail while in the scree. Waterton is a wonderful town with great people.
