Grand Baie is the main tourist hub of the north coast — busy, convenient, and unashamedly commercial. The beach is pleasant but not the best on the island. What Grand Baie has is infrastructure: the highest concentration of restaurants, shops, dive operators, boat excursion companies, and nightlife outside Port Louis.
It's the main departure point for catamaran day trips to the uninhabited northern islands — Coin de Mire (Gunner's Quoin), Île Plate (Flat Island), and Round Island. These trips typically include snorkelling, a fresh seafood lunch on board, and a few hours on an empty beach. Highly recommended.
Deep-sea fishing charters also operate from Grand Baie. Marlin, sailfish, and yellow-fin tuna are all caught in these waters. The season peaks from October to March.
The town is walkable, with a main road lined with shops and a waterfront. The Super U supermarket is useful for stocking up. If you're looking for somewhere quieter to sleep, nearby Péreybère and Cap Malheureux are calmer alternatives a few kilometres up the coast.
