Blue Bay is a coastal village in southeastern Mauritius, within the district of Grand Port and close to Sir Seewoosagur Ramgoolam International Airport. It is best known for Blue Bay Marine Park, a protected lagoon where coral reefs and clear shallow waters support a rich variety of marine life. The village sits beside a curved sandy beach and sheltered bay, with views across the lagoon toward small offshore islets. Its location also places it near Mahébourg, one of the island’s important historic towns, making Blue Bay a convenient base for exploring the southeastern coast and its maritime landscapes.

Blue Bay and the surrounding Grand Port region have a strong connection with Mauritius’s maritime history. Nearby Mahébourg contains landmarks and museums that explain the island’s colonial and naval past, including the National History Museum at Château de Robillard. Local culture also reflects the wider Mauritian blend of Indian, African, European, and Chinese influences, visible in food, religious traditions, music, and everyday life. Fishing remains part of the coastal economy, while boat operators in Blue Bay have developed activities around the marine park. The area therefore combines a working coastal community with a strong marine heritage.

Blue Bay Marine Park is the area’s principal attraction, protecting a section of lagoon with coral gardens, seagrass, and numerous reef fish. Glass-bottom boat trips and snorkeling excursions provide access to the shallow reef environment, while diving is available farther offshore. The marine park is also home to species such as green and hawksbill turtles. Blue Bay Public Beach offers direct access to the lagoon, while nearby Pointe d'Esny is known for its long beach and coastal vegetation. The southeastern shoreline also provides views toward Île aux Aigrettes, a protected nature reserve known for its conservation work.

Seafood features prominently in the food culture of Blue Bay and the wider southeastern coast, with fish, prawns, octopus, and other marine ingredients appearing in local dishes. Mauritian favorites such as dholl puri, rougaille, and fish curry are also widely available around the region. A distinctive detail about Blue Bay is the coral diversity within its marine park, which includes large stands of branching and massive corals in relatively shallow water. The bay’s calm conditions and protected reef environment make it an important site for marine education and conservation as well as recreation, giving the village significance beyond its beach setting.
