Plongée à Trou aux Biches — Mauritius

Trou aux Biches is Mauritius' most popular dive coast, where warm lagoon water gives way to outer reef walls dropping into deep blue. The Cathedral — a stunning cave dive with shafts of light — is the signature site. Luxury resort infrastructure and the famous 'underwater waterfall' illusion from the air make this a complete destination.
