Set amid the coastal Chugach Mountains, Anchorage defies popular visions of polar ice caps and frozen tundra. It’s also warmer than you think (averaging 65 degrees in summer), making conditions ideal for sight-seeing or taking on uniquely Alaskan opportunities like arctic biking or touring the fjords of Prince William Sound. In the winter, you can ski, dogsled or do both simultaneously by "skijoring," which is cross-country skiing while being towed by a dog. Hey, it's no crazier a winter sport than the biathlon.
