Lake Minnewanka is a stunning glacial lake located just a short drive from the town of Banff. What sets this area apart from others in the area is that you can take a scenic boat tour out on the water.
It makes for the perfect early evening activity after a more active morning hiking elsewhere in the park. For the best experience, time your boat tour in the early evening to align with sunset.
I'd suggest booking this activity in advance since popular time slots can fill up well in advance.
