A network of hiking trails crisscross the wild and empty Black River Gorges National Park. Unfortunately, they're not always well marked, so check the route and trail conditions at the information centres before setting off. Look for the rare tambalacoque (dodo tree), the black ebony trees and the wild guavas. Bird-watchers should keep an eye out for the Mauritius kestrel, pink pigeon, echo parakeet and Mauritius cuckoo-shrike.
L'Aventure du SucreThis excellent museum in the former Beau Plan sugar factory not only tells the story of sugar in fascinating detail, but along the way covers the history of Mauritius, slavery, the rum trade and more. The factory was founded in 1797 and only ceased working in 1999. Most of the machinery is still in place and former workers are on hand to answer questions about the factory's history and the complicated process of turning sugar cane into crystals.
Sir Seewoosagur Ramgoolam Botanical GardensThese attractive gardens are one of the most popular tourist attractions in Mauritius, but the shady avenues seem to swallow the crowds. One key attraction is the park's giant Victoria regia water lilies, native to the Amazon. There's also an astonishing collection of palms of all shapes and sizes.
