What's this attraction about?
Menehune Ditch was a massive irrigation system built with lava stone. The waterways brought water from the Waimea River to the taro fields. Lava rocks used to construct the ditch came from Mokihana, over than 6 miles away from the irrigation system. Remainders of the ditch can be seen today, though much of the system has been destroyed or eroded.
History
Historians are impressed yet dumbfounded by the Menehune Ditch—no one knows exactly who or how the irrigation system was built. Archeologists believe the ditch was constructed before Polynesians arrived on the island. Hawaiian legend states that local leprachaun-like people, called Menehune, built the ditch in one night, under the direction of Waimea’s high chief, who told all villagers not to go outside nor disturb the Menehune at work.
