ON-PISTE ACTION Crested Butte, Colo.
Ride up—and scream down—groomed alpine ski trails at Crested Butte Mountain Resort before or after the ski day. The climb from the base area (at 9,380 feet) to the top of Red Lady (10,350 feet) or Painter Boy (10,175 feet) is a serious high-altitude huff, but the rip back down the ski runs is all reward. Rent bikes at the Crested Butte Rental and Demo Center. skicb.com
