The region along the 767 mile (1235 km) highway loop from Kicking Horse West along the Trans Canada Highway #1 to Revelstoke, South along highway 23 and highway 6 passing by Whitewater Ski Resort to Red Mountain, then East along highway 3 to Fernie and then North along highway 95 to Kimberley Alpine Resort, Fairmont Springs, Panorama Mountain and back to Kicking Horse, is known as "The Powder Highway".
(Note that the route between Revelstoke and Whitewater includes a ferry service (Waterbridge Ferries: 1-250-265-2105) across Upper Arrow Lake at Shelter Bay, just 30 miles South of Revelstoke, so your actual route may vary)
This area is home to eight full service alpine resorts, ten cross country ski centers, nine heli-ski operators, 15 guided snowcat operators, and 21 backcountry ski touring outfitters who all benefit from the long powder season and generous snowfall.
Backcountry lodges and hut skiing are plentiful.
Known as the Kootenay Rockies, this region is not convenient to get to as the closest international airport is Calgary, but those who travel here come for its plentiful snow and scarcity of people.
The towns are rustic, charming old mountain mining towns that offer the essentials, so you may have to hunt for good souvenir T-shirt shop but not for powder.
