Hawaii is known for its volcanoes from which molten lava flowed and created marvelous formations. The Hana Lava Tube is the 18th largest in the world, formed a thousand years ago. The tube is located next to a botanical garden and maze and is a welcome break from the heat and humidity of the islands. (Photo by Lizzie De Oca)
