Glacier Skywalk
Jasper, Alberta
A walk along a cliff edge trail takes visitors to a U-shaped walkway with a glass floor, hanging 918 feet above the Sunwapta Valley. Visitors take a mini-bus from the Columbia Icefield Glacier Discovery Centre for a short ride that drops them off at a trailhead, then stroll to the Skywalk.
Opened in 2014 at a cost of $21 million Canadian dollars, the Skywalk was built by a private company that claimed that a Canadian bus driver came up with the idea in 2007 -- not surprisingly, the same year that the remarkably similar Grand Canyon Skywalk opened in the USA.
Some Canadians are unhappy with their Skywalk, worried that it upsets the native bighorn sheep and mountain goats. In a written statement, Parks Canada defended the for-profit Skywalk (which was built inside a national park) as part of a larger plan to become "more relevant."
