Just off the south east coast of Mauritius, in the lagoon of the Mahebourg coastal village, is one of the most historically significant islets of Mauritius, Ile de la Passe.
Strategically placed just beyond the ancient harbour of Vieux Grand Port, Ile de la Passe was a key factor in the defense of the island. Under the French rules, various forts and cannons were built on the island to wave off the British invaders. The ruins of these constructions are still visible and in surprisingly good condition. The site was also the location of the legendary Battle of Vieux Grand Port which the French navy won.
It takes only a 20 min boat ride to get to Île de la Passe , after which you can spend a pleasant half day walking through the ruins of the ancient French defense and awing at them.
