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.
Mauritius' sole national park is a spectacularly wild expanse of thick forest covering 3.5% of the island's surface and home to over 300 species of flowering plants and nine species of bird unique to Mauritius, including the famous pink pigeon which is staging a very gradual comeback from the brink of extinction.
