The Islas Cíes form part of the Atlantic Islands of Galicia National Park — a low archipelago at the mouth of the Ría de Vigo, with crescent-shaped white sand beaches, clear turquoise water, and a permanent population of zero. The islands are uninhabited, undeveloped, and limited to a fixed number of day visitors. There is one small campsite and a handful of restaurants near the ferry dock.
Ferries leave from Vigo, Cangas, and Baiona between mid-spring and early autumn. Allow a full day — go early, walk to the Faro lighthouse for the panoramic view, and spend the afternoon on Praia de Rodas. Book the ferry and permit well in advance; July and August fill weeks ahead.
