Molokai is the fifth largest island of the Hawaiian archipelago, located between Oahu, Maui and Lanai. Spanning 38 mi (61 km) in length and 10 mi (16 km) in width, Molokai boasts a variety of terrains, from the rainforests of Kamakou Preserve to the sandy shores of Papohaku and Murphy's beaches to rocky hillsides at Pala'au State Park. Beneath its beautiful exterior lies a tragic past, as the island once held native Hawaiians who were exiled in the 1800s. From 1895 to 1969, the island harbored a leper colony, and today visitors can learn about this history at Kalaupapa National Historical Park. Molokai's pristine and undeveloped natural environment makes it popular with eco-tourists. Local companies add to Molokai's enjoyment, such as Molokai Outdoor Adventures, Gypsy Sailing Adventures and Molokai Mule Ride. As birthplace of hula, Molokai hosts the Ka Hula Piko festival each May to celebrate the Hawaiian dance.
