Geography of Hawaii
Hawaii is located approximately 2,000 miles from the US mainland and like Alaska, it does not border any other US state. It is also the southernmost state in the US and the only state in the country which is not located in North America. Out of the eight islands, only seven are permanently inhabited, and the island of Ni’ihau is privately managed, and access is restricted by the managers. The tallest mountain in Hawaii is Mauna Kea extending to 13,796 feet high from the mean sea level. However, when measured from the base which is on the floor of Pacific Ocean it reaches 33, 500 feet high, making it taller than Mt Everest.
