Kapaa, city, Kauai county, on the east-central coast of Kauai island, Hawaii, U.S. Sugarcane and pineapple plantations once dotted the region around Kapaa. Rice was also grown, and Chinese merchants once dominated the commercial centre. Since the 1960s, tourism, diversified agriculture, and service industries have become the main sources of income, replacing pineapple growing. Various legends, reminiscent of Gulliver and the Lilliputians, are connected with the Sleeping Giant, a mountain formation a few miles south of Kapaa. Another nearby feature is Holoholoku Heiau, restored (1933) by the Bishop Museum of Honolulu and one of the oldest heiaus (ceremonial and religious structures) in Hawaii; it contained the sacred birth stones where Kauai queens went to bear their children. The temple was sacred to the war god Ku, whose rites included human sacrifice. The Kauai Children’s Discovery Museum (1995), which features art and science exhibitions, is located in Kapaa. The historic Wailua River Reserve, the site at which the second wave of Tahitian settlers is thought to have landed, is nearby. Pop. (2000) 9,472; (2010) 10,699.
