This dive site, the Lagon de Saint-Leu, is situated conveniently close to the town centre of Saint-Leu on Réunion Island. It is a very shallow and protected lagoon, naturally enclosed by a coral reef and further secured by a small marina, which ensures a safe environment for swimming and underwater exploration. Due to its easy accessibility from the beach and popularity, it is frequently crowded, particularly during weekends. Underwater navigation is simple and straightforward within the confined and shallow confines of the lagoon.
The Lagon de Saint-Leu boasts a fine coral garden that serves as a vibrant habitat for a rich diversity of marine life. Visitors can expect to encounter numerous small fishes and various invertebrates thriving within the reef's ecosystem. While the extremely shallow maximum depth of 2 meters means large pelagic species are not typically found here, the site is excellent for observing macro life and the intricate details of a healthy reef.
The best time to visit Lagon de Saint-Leu might be during weekdays to potentially avoid the larger crowds, although its protected nature generally makes it accessible year-round. It is an ideal location for novice divers, snorkelers, and those looking to practice shallow water skills. Freedivers can also enjoy the easy access and practice opportunities, though the limited depth means it's more suited for breath-hold training than deep exploration. Visitors should be mindful of other beachgoers and the delicate coral environment.
