Galatea Lakes in Kananaskis Country is just an hour from Calgary, the closest big city. It’s the perfect hike on a hot summer day as you mostly hike sheltered in the forest and visit three stunning lakes.
Overall it’s an 18 km (11 mile) roundtrip hike with moderate difficulty. If you’d like an easier lake hike that is family-friendly, Grassi Lakes near Canmore is amazing, featuring two emerald lakes, and it’s only 4 km (2.5 mile) roundtrip.
The trailhead is located at the Upper Hot Springs. Through a series of switchbacks with continual incline and an occasional view of Rundle Mountain, you reach the top of Sulphur Mountain in about two hours.
