At just a little over 4,000 square miles (95 miles from north to south and 80 miles from east to west), Hawaii is the youngest and largest of the seven Hawaiian Islands. Five volcanoes formed the Big Island (as Hawaii is known) and one, the Kilauea volcano, is still active. It’s a bit of a walk to get to the Kilauea volcano crater once you enter Hawaii Volcanoes National straight line. Geologists believe these undersea mountains, and the Hawaiian Islands, were once above a fixed point on the ocean floor; all were created as tectonic plates shifted.
