Just a few minutes drive from Banff, this day trip is highly recommended. We first went to Lake Minnewanka (great name btw) and took the cruise of the lake. If you took the chair lift at Banff, you can also add on this cruise for a little extra. After the cruise we then drove to Lake Johnson. This was the highlight of the day. This beautiful lake has a very gentle walking track around its edge. Took us about 90 mins to complete the walk. We even stopped and took a quick swim. It's was a beautiful hot day in Sept and the water was very still and clear (water was pretty cold so it was a quick swim). There were only a few cars in the car park. It seems not many visitors know of this hidden gem. For those wanting to visit a beautiful lake with a gentle and easy walking trail, this would be my number one choice.
