The boat drops you at one point and picks you up at the same one. In between you have five to eight hours, depending on your sailing. Plenty for the essentials, but it helps to know what you can walk on and what you cannot.
This is the postcard: an arc of brilliant white sand that acts as a natural bridge between the two islands and encloses O Lago, a lagoon that shelters breeding fish and other wildlife. The water is crystal clear and cold — several July reviews call it "very cold", without drama. It is simply the Atlantic.
The star walk, and reason enough to come even if you never swim: a made-up path climbs to the lighthouse on Faro island, with the archipelago's western face dropping into the ocean in cliffs over 150 metres high. One July review adds a useful practical note: it is a path you can push a pram up.
Advice repeated by people who went: water (plenty), a warm layer and a rain jacket — even if you leave Vigo in sunshine — and shoes you can actually walk in. The boat deck is cold even on a fine day. And sunscreen: there is little shade on the trails.
Dogs are not allowed on the boat to the islands.
First things first: without the Xunta permit you do not board.
