When looking up towards the Ha Ling Peak from Canmore, you’d think there possibly cannot be any path leading up. In fact, the trail up to Ha Ling peak is a well maintained 7.5 km long hike that you can tackle in half a day, any time of a year (just don’t forget to pack the microspikes or ice cleats in the winter). With almost 800 meters of elevation gain, it is a steep one, but there aren't any technical sections.
This is one of the Canmore & Kananaskis classic hikes that you shouldn’t miss, but be prepared that it gets busy due to its proximity to town. Goat Creek Day Area provides decent amount of parking, though it can still fill up on the weekend, so make sure to count with that into your plans.
