Alaska tours feature breathtaking scenery of towering glaciers, pristine wilderness and majestic mountains. A "big land" of immense natural beauty, Alaska has so much to offer visitors. Your Alaska vacation might include a trip on the famous Alaska railroad, through untamed wilderness to Denali National Park, where you'll find North America's highest peak, 20,320-foot Mount McKinley.

With its thousands of miles of coastline, it only makes sense to spend part of your Alaska tour on the water. One day trip from Anchorage is a cruise of Kenai Fjords National Park, and from Valdez, you can cruise Prince William Sound - both feature opportunities to view not only glaciers but wildlife you may not see back home. The entire state is filled with wild and wooly creatures. (Don't forget to pack your binoculars and a good zoom lens!) On Alaska tours, visitors have opportunities to view moose, bear, caribou, wolves, whales and sea lions, just to name a few animals.

Another interesting highlight on an Alaska vacation: a stop at the Iditarod Headquarters, home of the world-famous dog race. Check out the museum detailing the history of the race, and learn about the dogs (and their mushers) who traverse more than 1,100 miles across rugged Alaska - from jagged mountain ranges to frozen tundra - in the middle of winter.
