Ilha de Tavira
The ferry from Quatro Águas takes ten minutes, and for most of that crossing you're watching herons pick through the salt marsh while the water turns from brown to shallow jade. Ilha de Tavira is a barrier island in the Ria Formosa lagoon system — eleven kilometres long, rarely more than a kilometre wide, and fronted by a long Atlantic beach with Blue Flag water that stays bracingly cold even in August.
Most people arrive at the landing stage, walk the 350 metres to the nearest stretch of sand, and stop there. That's worth knowing, because ten minutes further west the crowd thins considerably, and forty minutes gets you to Praia do Barril and its strange, rusted monument.
💛 What travellers fall for
People who come back tend to take the longer route: the floating bridge from Pedras d'El Rei, then the narrow-gauge train through the marsh, arriving at Barril rather than the main ferry landing. Lunch at Zé Maria or Ilha Formosa, a walk west past the anchor cemetery, back by the last boat. The sequence matters.

From 1841 until 1967, the beach at Barril was a working tuna station. Around eighty families lived on the island seasonally, using the almadrava — a net-and-anchor technique with roots in Phoenician fishing practice — to intercept the Atlantic bluefin on their annual migration through the strait.
By the 1960s the tuna runs had collapsed, the station closed, and the heavy iron anchors that had held the nets were dragged up the beach and arranged in rows. They're still there: a few hundred of them, oxidising slowly in the dune grass. The fishermen's huts that once housed the workers now contain restaurants.

When to go
May through September is dry and sunny, with July and August pushing 30–33°C on land — though the sea rarely exceeds 22°C even at peak summer. Spring and October offer temperatures in the low-to-mid twenties with far fewer people. Winter days are mild at around 15–16°C, but December brings the most rain and the ferries run only once an hour.
