Boating among the small islets that form the archipelago is a must, and it's an excursion you can do in a day. Coves for bathing, trails for walking… time flies in paradise. There are several boat services from Porto-Vecchio that will take you on this wonderful cruise.
With its huge, white-granite boulders and beaches of white sand, Lavezzu Island, the largest of the archipelago, has amply earned its nickname as the ‘Corsican Seychelles, without the coconuts. Head to beautiful Achiarina beach on this island, just after the bay of Cala della Chiesa. The short walk to get there takes a bit more than half an hour.
Please note: the Lavezzi islands are unsullied by municipal infrastructures, so bring your own water and whatever else you might need not to be caught off guard. Also, watch out for stinging jellyfish.
