Not a beach but a natural pool carved in limestone, where the sea turns so clear that boats seem to fly: the Piscine di Venere are the definitive snorkelling stop on the Baunei coast.
The Gulf's aquarium
The white seabed reflects light and turns the water a luminous turquoise that hardly seems real. Below: bream, damselfish, octopus in the cracks and — with patience — a peeking moray. No expertise needed: the pool is sheltered and calm.
How the stop works
Boats pause 30-45 minutes: you swim straight off the deck. Morning departures find the stillest water; in the afternoon, raking light ignites the sheer limestone walls.
Extra tip
If you rent your own dinghy, arrive before 10am or after 4pm: you will have Venus's pool almost to yourself — a privilege worth the alarm clock.
