This former sugar-mill superintendent’s home has been converted into a museum that tells the story of sugar in Hawaii. Exhibits explain how workers of a variety of ethnic backgrounds grew, harvested, and milled sugarcane—backbreaking toil that also relied on innovative engineering. An eye-opening display shows how Samuel Alexander and Henry Baldwin managed to acquire huge chunks of land from the Kingdom of Hawaii, then fought to gain access to water on the other side of the island, making sugarcane an economically viable crop. Allow about half an hour to enjoy the museum, and don’t forget to stop for plantation-themed sweets in the gift shop.
