Fodor's Expert Review Alekoko (Menehune) Fishpond
No one knows just who built this large, intricate, almost 1,000-year-old aquaculture structure in the Huleia River, but legend attributes it to the Menehune, a mythical—or real, depending on who you ask—ancient race of people known for their small stature, industrious nature, and superb stone-working skills. Volcanic rock was cut and skillfully fit together into massive walls four feet thick and five feet high, forming a centuries-old enclosure for raising mullet and other freshwater fish. Volunteers removed invasive mangroves and restored the pond to its original condition. You can view it from an overlook about 4 miles from downtown Lihue.
