Jasper National Park is home to the Columbia Icefields which include Athabasca Glacier, the most-visited glacier in all of North America. While it's free to visit, if you want to walk on Athabasca Glacier, you'll have to sign up for a tour led by professional guides. If you'd rather see these massive sheets of ice from the comfort of your car, drive the Icefields Parkway between Jasper and Banff. It often shows up on lists of the world's most scenic drives.
