Alaska is located in the upper northwest of the North American continent. It is in the United States, although it is separated from the contiguous United States by Canada. It was purchased from Russia in 1867, and officially became the 49th state in 1959. Sizewise, it is by far the largest in the US. However, it has one of the smallest populations, at less than 650000.
Alaska is separated from Russia by the Bering Strait, and is bordered on the east by the Canadian Provinces of British Columbia and Yukon Territory. Juneau is the state capital, and the third most populous. It is located in the southeast part of the state, in area that runs between British Columbia and the Gulf of Alaska, and interestingly, is not accessible by road, rather only by air and sea. The second largest city is Fairbanks, located east and a little bit south of the geographical center of the state. The largest city, with around 260000 people, is Anchorage, located in the south of the state, near the Gulf.
Getting to Alaska is easiest by plane, as Anchorage and Fairbanks have major airline service, and in Anchorage is Anchorage International Airport. If you have plenty of time, you can also drive there via the Alaska Highway, which runs from the US through Canada. Alaska is somewhere around 500 miles north of the Canadian border, and the drive is likely longer. You can also get to Alaska by ferry from Washington. Unless you are near the major road systems, getting around once you are there might be most efficient by plane, however it can be expensive.
