A small rocky island just offshore, about 8 hectares in area and rising to 53 metres at its highest point. Since 1985 it has been protected as a regional nature reserve and designated a European Site of Community Importance, which means landing without authorisation is restricted and the surrounding waters are carefully managed.
The island's shoreline is dense maquis — sea fennel, tree spurge, the endemic Campanula sabatia — and its cliffs drop straight into some of the clearest water on this stretch of coast. You can reach it only by boat, but the real experience is underwater: the marine reserve has significantly boosted fish populations and the rocky bottom here is covered in gorgonian fans, sponges, and moray eels.
From the beach or a boat you can clearly see the medieval watchtower on the island's summit, built to spot approaching Saracen raiders from the same vantage point used by Roman and pre-Roman settlers before it.
