Central Alaska is home to Denali National Park, a wilderness characterized by towering mountains, large glaciers and a host of wildlife. One of the most exciting ways to see the park is aboard a guided bus tour that ventures to an authentic wilderness lodge. Anchorage, Alaska's largest city and the center of commerce for the state, has a climate that is surprisingly moderate compared to the rest of Alaska. The world-famous Iditarod dog-sled race begins at Anchorage each spring. Amongst the region's most impressive attractions are the Anchorage Museum of History and Art, the Alaska Zoo and Chugach State Park. The main supply center for the oil industry and Arctic Alaska is Fairbanks, which is also located at the center of the state. Ester Gold Camp, a historic mining town established in the early 20th century, offers dinner buffets and saloon-style entertainment shows. A popular Central Alaska activity is boating on the Chena and Tanana rivers.
