Anchorage is Alaska's main city and is home to more than half of the state's total population. Compared to the rest of Alaska, the city's climate is relatively moderate. Anchorage has some interesting historic sights and museums, such as the Anchorage Museum of History and Art and the Alaska Aviation Heritage Museum. Other Anchorage attractions worth exploring are the Alaska Zoo, The Imaginarium science center and the Alaska Native Heritage Center. The city is the starting point for the annual Iditarod, a world-renowned dog-sled race. Just east of Anchorage is the third largest state park in America, Chugach State Park, which covers a half-million acres of terrain rife with opportunities for outdoor adventure. Hiking, skiing, camping and climbing are just a few of the activities that await Anchorage area visitors. Sportsmen appreciate the wealth of fishing and hunting charters the city has to offer.
