Sail out into the Galician Atlantic Maritime Reserve during summer and explore the Cies Islands. This tiny archipelago is known as ‘Spain’s Seychelles’, and the long white beaches and lovely lagoons are similar. But, unlike the Seychelles, these eco-icons are uninhabited, car-free, and limit visitor numbers.
If a day isn’t long enough, come stay in a ready-pitched tent at the Cies campsite. It’s in a conservation area, but two excellent local restaurants keep you from going hungry. And the beachfront location on Praia de Rodas, one of Condé Naste Traveller’s top 10 best beaches in Europe, makes it the most popular campground in northern Spain, so advance booking is essential.
