For my birthday this year, I got a ride on the Banff Gondola, which included an easy hike along a mountaintop boardwalk with views in all directions. At $51 to $63 per person, the excursion is pretty expensive, but I’d say it was totally worth it.
I will be posting some of my photos from the summit of Sulphur Mountain. Today (and everyday) you can check the webcam there to see how the view changes with the seasons. As of October 10, the mountains are covered in snow.
