Île de la Passe (Mauritius)

Île de la Passe is a small islet at the entrance to the Grand Port lagoon on the southeast coast of Mauritius, in Grand Port District.

The islet was strategically important during the Napoleonic-era naval clashes around Mauritius and was a focal point in the 1810 Battle of Grand Port. It remains notable in local history for its role in controlling access to the sheltered lagoon.

The islet lies close to the main lagoon channel off Mahebourg and is visible from the shoreline; it has no permanent settlement and is reached only by small craft.

• Historic significance: Site associated with the 1810 Battle of Grand Port, the major naval action off Mauritius during the Napoleonic Wars and commemorated in French and British naval history.
• Location note: Located at the entrance to the Grand Port lagoon near Mahebourg, visible from the coast and commonly referenced in local historical tours.

What to See#

• Historic battlefield area: The islet and its surrounding reef were tactical focal points during the naval actions of the 1810 Battle of Grand Port, when control of the pass into the lagoon determined movement of warships.

Short boat trips depart from various harbors on Mauritius’s east and south coasts; private charters and organized day tours commonly include Île de la Passe as part of lagoon cruises.

• Observe local regulations-some islets have restrictions to protect nesting birds and coral.
• Bring snorkeling gear if sea conditions permit; the waters around the island can be very clear.
• Check tide tables and sea-state forecasts before attempting small-boat landings.
