This map was excerpted from the very excellent Natural Resources Canada "Toporama" website.
While this map includes Lake Louise in Banff National Park on the right edge, the real focus is on the highlights of Yoho National Park. Look on this map for Emerald Lake, Lake O'Hara, Field, and Takakkaw Falls in the Yoho Valley. Another easily accessible and famous viewpoint is the "Spiral Tunnels" overlook on the CPR rail line just west of Kicking Horse Pass.
