Alaska adventure and activity holidays from the adventure travel experts at Exodus. Alaska is one of the great wildernesses of the world, the last American frontier! For years the most neglected part of the Union, but now with its reputation firmly established for both oil and tourism. The sheer size of Alaska is quite daunting, with 5,000 glaciers, including one the size of Switzerland, and vast areas of uninhabited wilderness. Its total area is over a million square kilometres, yet there are only about 500,000 permanent residents. It is by far the largest state of the USA, and includes vast empty tundra plains, mountains, glaciers, rivers and forests; all this combined with its fascinating history makes Alaska an ideal adventure travel destination.
