The sugar industry, along with tourism, is one of the nation's main industries. In fact, some 80% of the island is under plantation. The L'Aventure du Sucre interactive museum, located in the town of Pamplemousses just north of Port Louis, sheds light on the history of the crop, the story of the slaves brought in to work in the cane fields, and the abolition of slavery following the British defeat of the French in the early 1800s. Located behind the historic facade of an old sugar mill, the tour takes about 90 minutes and finishes with sugar and rum tastings. Visitors can combine a visit to the museum with the lovely nearby botanic gardens, known as the Sir Seewoosagur Ramgoolam Botanic Gardens.
