The hull cuts through the Mediterranean with a sharp, salty breath—Nice’s Port Lympia receding as the coastline bends toward the Lérins archipelago. In fifteen minutes the mainland blurs and the water takes over: clear, green-blue, and busy with life. Onboard a small speedboat you’ll feel the wake lift you, the sun on forearms, and the islands—their low pine crowns and stone ramparts—drawing nearer.

The hull cuts through the Mediterranean with a sharp, salty breath—Nice’s Port Lympia receding as the coastline bends toward the Lérins archipelago. In fifteen minutes the mainland blurs and the water takes over: clear, green-blue, and busy with life. Onboard a small speedboat you’ll feel the wake lift you, the sun on forearms, and the islands—their low pine crowns and stone ramparts—drawing nearer.
Sainte-Marguerite, the largest of the islands, bears and guards a short, layered history: a 17th-century Fort Royal once doubled as a prison and the rumoured cell of the Man in the Iron Mask. Geologically the islands are Provençal limestone outcrops rimmed by pebble coves and fringing seagrass—Posidonia meadows below sustain an underwater community that the local ecomuseum aims to protect and showcase.
The trip balances quick, vivid encounters: a guided snorkeling window amid protected marine life, an hour ashore to wander gardens and a fortress, and a slow pass of the Baie des Milliardaires where villas peek through pine. Expect practical constraints—no restroom onboard, light luggage only, and firm rules about swimming ability.
Prepare to move between boat and shore, wear reef-safe sunscreen, and respect marked underwater habitats. Guides supply masks, snorkels, life jackets; bring a light towel, reef shoes, and a waterproof phone bag. The outing is compact—about four hours total—making it an efficient, sensory introduction to the Riviera’s marine and island heritage for swimmers and keen first-time snorkelers.
