Chapter 18: Hawaii

Hawaii is the most recent of the 50 U.S. states (joined the Union on August 21, 1959), and is the only U.S. state made up entirely of islands. It is the northernmost island group in Polynesia, occupying most of an archipelago in the central Pacific Ocean.

Hawaii’s diverse natural scenery, warm tropical climate, abundance of public beaches and oceanic surrounding, and active volcanoes make it a popular destination for tourists, surfers, biologists, and volcanologists alike.

Hawaii is the 8th-least extensive, the 11th-least populous, but the 13th-most densely populated of the 50 U.S. states. Hawaii's coastline is approximately 750 miles (1,210 km) long, which is fourth in the United States after Alaska, Florida and California.

Like Hawaii, San Francisco is a famous tourist spot. San Francisco attracts the fourth-highest number of foreign tourists of any city in the U.S. and claims Pier 39 near Fisherman's Wharf as the third-most popular tourist attraction in the nation. More than 16 million visitors arrived in San Francisco in 2011, injecting $8.5 billion into the economy. With a large hotel infrastructure and a world-class convention facility in the Moscone Center, San Francisco is also among the top-ten North American destinations for conventions and conferences. In a Euromonitor International ranking of top city destinations, San Francisco was ranked the 33rd most visited city in the world out of 100 of the world's most visited cities.
