La Preneuse (beach) – located about an hour southwest of Port Louis, this is a popular public beach that also has one of the most well preserved Martello Towers on the island. The beach itself is not on the beaten tourist track and is therefore much quieter and far less crowded than the more well-known beaches on the northern part of Mauritius. La Preneuse is a good base for dolphin watching, and there are usually skippers around to take you out on a trip against a small fee. Both Spinner dolphins and Bottlenose dolphins are frequently seen off of the coast in large numbers. For good snorkeling spots, head away from the main beach and walk either north towards Tamarin, or south towards Grande Rivière Noire, where you will find colorful tropical fish in abundance.
