Boat snorkel outing in the Molène archipelago.
Boat snorkel outing in the Molène archipelago.
Rando Palmée Archipel Molène is a guided boat snorkel outing that crosses the Chenal du Four into the Molène archipelago for a shallow swim among kelp beds and seaweed-covered seabed. The trip is as much about the journey as the water: boat handling, marine-mammal watching and a calm, unhurried in-water stop in a wild Atlantic setting. It suits confident beginners who are happy on a boat and comfortable around open-sea conditions.
