Summer dog sledding on the icefields and glaciers of Alaska was started in the mid-1990's, and Alaska Icefield Expeditions has two camps, each with over 200 dogs. Visitors have the thrill of a helicopter ride to and from the glacier, along with an opportunity to meet the dogs and mushers and ride in a dog sled across the snow and ice. The helicopter ride alone is a great adventure, but the dog sledding made it extra special.
The truly adventurous can spend the night in a private hut at the glacier camp and learn to mush their own team of dogs. Doesn't that sound like fun?
One note--this excursion is expensive and is sometimes canceled due to inclement weather.
