Black River Gorges National Park

Mauritius' biggest and best national park is a wild expanse of rolling hills and thick forest covering roughly 2% of the island's surface. It's difficult to overstate the importance of this park – it's the last stand for Mauritian forests and many native species. It's also the most spectacular corner of the island, so if you make only one day trip from the coast, make it here, perhaps combining it with Chamarel.
