Both scenic and historic, Miles Canyon is a short drive south of Whitehorse. Although the dam below the canyon makes its waters seem relatively tame, it was this perilous stretch of the Yukon River that determined the location of Whitehorse as the starting point for river travel north. The dam, built in 1958, created a lake that put an end to the infamous White Horse Rapids. Back in 1897, though, Jack London won the admiration—and cash—of fellow stampeders headed north to the Klondike goldfields because of his steady hand as pilot of hand-hewn wooden boats here. You can hike on trails along the canyon or rent a kayak and paddle on through.
