Since Whistler Mountain opened in the mid-'60s, the amount of accessible terrain, mountain restaurants and the number of runs has grown substantially.
Blackcomb Mountain opened to the public in 1980, and for two decades afterwards, the duelling resorts competed to be the best in the province.
In 2003, the two mountains united officially as Whistler Blackcomb, and shortly after won the bid for the 2010 Olympic Games.
