A number of Iditarod and Yukon Quest mushing champions have turned their love of the sport into a thriving tour business. Winter is high season for one-day and multi-day mushing trips, but there's plenty to do in summer, too: You can tour a musher's kennel, pet the sled dogs, learn how they're trained and ride in a wheeled cart pulled by the dogs. Or take a helicopter ride up to a glacier and ride a dog sled in the snow as Alaska's endless summer sun shines down around you.
