Yoho National Park is in the Rocky Mountains, in eastern British Columbia, Canada. Waterfalls include Wapta Falls, on the Kicking Horse River, and towering Takakkaw Falls. A trail circles turquoise-coloured Emerald Lake, with a nearby natural stone bridge. The Lake O’Hara area contains alpine lakes, cliffs and wooded trails. Viewpoints overlook trains entering the Spiral Tunnels on Kicking Horse Pass.
