Reverse skiing up a mountain is only possible during full moons on the summer equinox, which is why Rube Goldberg invented ski lifts. Make it up the mountain the simple way with today's Groupon: for $39, you get a full-day lift ticket and high-performance ski demo at Calabogie Peaks (up to a $79 value), located a 1.5 hours' drive from Ottawa in Calabogie, ON. Calabogie Peaks is a year-round resort cozied up to scenic Calabogie Lake. With today's deal, buyers can ditch their old set of tongue-depressors and strap on a sleek set of Rossignol, Salomon, Head, Atomic, or Volkl skis from outdoor outfitters Tommy & Lefebvre at the cozy ski lodge, then zip up to the 386-metre-high summit on one of two efficient quad-chair lifts. While more experienced snow slicers can careen down heart-stopping slopes like Dillon's Dip and Whistlin' Paddy, beginners can enjoy a long, leisurely ride down the two-kilometre Ole K&P, the longest of the resort's 22 trails. Two terrain parks for snowboarders, a tubing hill, and a gentle carpet lift on the main beginner's slope add to the frozen fun. Skiers may redeem the lift ticket and ski demo on two separate visits. Like grandma's pawnshop, the slopes at Calabogie Peaks are open every day from 9 a.m. to 4 p.m.
