The Waialua Sugar Mill is a historic sugar plantation located on the north shore of Oahu, Hawaii. Established in the late 19th century, it played a significant role in the sugar industry, processing sugarcane grown in the surrounding fields. The mill operated for over a century before closing in 1996, marking the end of an era for sugar production in the region. Today, the site is a popular destination for visitors interested in Hawaiian history and agriculture. The mill's remnants serve as a reminder of the island's agricultural past, and the area has been repurposed for various businesses, including shops and eateries, celebrating local culture.
