The only rice mill on the island of Kaua’i, and in the whole of Hawaii, is Ho’opulapula Haraguchi Rice Mill in Hanalei Valley, to the north of the island. For this reason, you will need to fly into Lihue Airport as it is the closest airport to the rice mill. Listed on the National Historic Register of Historic Places, the rice mill is 48.9 km from the airport, about a 44min drive or a 2h 4min bus journey.
