Created by local divers and artists in the 2010s to give Golfo Aranci a cultural draw of its own, distinct from the Costa Smeralda nightlife two headlands away. Anchorage: Anchor in Golfo Aranci in 6-10m sand, good shelter from mistral; steps from the Costa Smeralda circuit. Hazards: No site-specific hazards noted, brief normally. Más
