Black diamond Mont Tremblant, QC
Réaction drops 479 vertical feet over 1,905 feet of skiing, with a steepest pitch of 25° about 860 feet below the top. That's steeper than 25% of the 4,740 black diamond runs we've measured in North America, and the 32nd steepest of 128 named runs at Mont Tremblant. It faces southeast.
Facing southeast at an average 15°, Réaction gets about 116% of the winter sun that flat ground at Mont Tremblant does, December through March. That's sunnier than 84% of the runs we've measured, and the 43rd sunniest named run at Mont Tremblant. Its top sits at 2,710 feet.
Angled toward the low winter sun, it bakes: powder turns heavy soon after a storm, and in spring it softens early in the day and refreezes hard overnight. Shading from ridges and trees isn't counted yet.
