North (Grand Baie, Pereybere, Trou aux Biches, Mont Choisy): calm shallow sea, most restaurants and bars, boat trips to the islands, busiest. Best first-time base.
West (Flic en Flac, Tamarin, Le Morne): calm deeper sea, sunsets, dolphins, Le Morne and the mountains behind. Best for a mix of beach and hiking.
East (Belle Mare, Trou d'Eau Douce, Poste Lafayette): long empty public beaches, wind in winter, Île aux Cerfs, quieter and more expensive hotels. Best for doing nothing well.
South-east (Blue Bay, Mahébourg): best shore snorkelling, real town, close to the airport, few hotels. Best for a short trip or the first and last nights.
South (Souillac, Bel Ombre): cliffs and wild coast, a handful of resorts on the Bel Ombre lagoon, the least visited. Best for a second visit.
