Sirius Wreck

The Sirius Wreck is a historical dive site located off Mahébourg and Pointe d’Esny, resting at a depth of around 25 m. The site contains the remains of the HMS Sirius, a British frigate sunk during the Battle of Grand Port in 1810, one of the most famous naval engagements in Mauritian history.

The wreck is now scattered across the sandy bottom and partially covered by coral growth, creating a unique mix of history, reef life and gentle conditions suitable for intermediate divers.

A Historic Wreck from 1810

The HMS Sirius was part of the British fleet during the Battle of Grand Port. After running aground and sustaining heavy damage, the ship sank near the outer reef. Today, its remains form a dispersed wreck site with identifiable metal structures and coral‑covered fragments.

A 25‑Meter Intermediate Profile

With depths between 22 and 26 m, the site offers a comfortable mid‑depth dive suitable for intermediate divers. The sandy bottom and open layout make navigation easy.

Coral‑Covered Debris

Many parts of the wreck are now encrusted with hard corals, sponges and algae. The mix of metal and reef attracts a variety of marine life, including snappers, goatfish, lionfish and the occasional stingray resting in the sand.

Clear Water and Gentle Conditions

The south‑east lagoon and outer‑reef area often provide good visibility and mild current, making the site accessible and enjoyable for divers interested in history and marine life.
