Formed by volcanoes and steeped in a rich history of Polynesian culture, Hawaii sounds more like a place in a fantasy novel rather than an American travel oasis.

Made up of a chain of volcanic mountains that form eight major islands, Hawaii stretches about 1,500 miles. The state's vast expanse provides a diverse terrain for visitors to explore -- tropical rain forests, cool alpine regions, arid deserts and sunny beaches -- all within miles of one another.

The region's beauty, history and landscape have enthralled novice and seasoned travelers alike. American travel writer Paul Theroux once said, "Hawaii is not a state of mind, but a state of grace."
