Dog Sledding is a must. The blue-eyed huskies fire you up; they are raring to go, yipping with excitement and impatience as your guide gives you a crash (make that non- crash) course in how to steer, stop and go. (Yes, you really do say "mush" for go). Each sled and team of eight has a driver and a passenger who take turns driving. It's harder than just standing there, as dogs race over frozen lakes or snow-covered golf courses into forests of spruce and fir. Gaétan, is the gregarious guide you want to go out with. His English is on the limited side, but that just makes the experience that much more exotic.
Like many of the activities this can be booked through Tremblant's activity center, or through Expedition Wolfe in Labelle (The next town past Mont-Tremblant).
