The Ria Formosa is a lagoon protected by a chain of sandy barrier islands along the eastern Algarve, between Faro and Cacela Velha. The islands have long Atlantic beaches with no roads behind them, reached only by boat. Choose Ilha Deserta for the emptiest beaches and the southernmost point of mainland Portugal, Culatra and Farol for fishing villages and a lighthouse, Armona for a short ferry from Olhão, and Ilha de Tavira for the most facilities. Public ferries leave from Faro and Olhão, and boat tours combine several islands in a day.
This guide compares the islands, explains how to get to each one and covers the boat tours you can book.

What Is the Ria Formosa?
The Ria Formosa is a lagoon of channels, salt marshes and sandbanks sheltered from the Atlantic by barrier islands, including Barreta (Deserta), Culatra, Armona, Tavira and Cacela. It has been a natural park since 1978, and in 2010 it was voted one of the Seven Natural Wonders of Portugal. It is also an important stop for migrating birds.

The Islands
Ilha Deserta (Ilha da Barreta)
The only uninhabited island in the Ria Formosa, about 7 km long, with around 11 km of quiet beaches and dunes, wooden walkways and a naturist area. On its south side is Cabo de Santa Maria, the southernmost point of mainland Portugal. Facilities are minimal: the Estaminé restaurant, in the island's only building, serves coffee and meals, so book ahead in summer and bring water and shade. Ferries leave from the Porta Nova pier in Faro, and the crossing takes about 35 minutes.
Culatra
Culatra is about 6 to 7 km long and home to around 700 people in three communities: Culatra, Hangares and Farol. There are no cars. From the fishing village of Culatra, a boardwalk of about 1 km crosses the dunes to Praia da Culatra, a long, quiet Blue Flag beach with lifeguards in summer. Ferries run all year from Olhão and Faro, and the Olhão boat stops at Hangares and Farol on the way.
Farol
Farol, at the western end of Culatra, takes its name from the Cabo de Santa Maria lighthouse. Its beach is the liveliest on the island, with a beach bar and several restaurants. You can walk the 2.5 to 3.5 km between Farol and Culatra along the beach or through the dunes, passing the old naval outpost of Hangares.
Armona
The closest island to Olhão, about 15 minutes by ferry, with a small village and four beaches: calm, sheltered water near the pier and a wilder beach on the ocean side. It is a good choice for families and for water sports, with kayaking, paddleboarding and kitesurfing lessons. Boats also cross to the eastern end of the island from Fuseta.
Ilha de Tavira
The liveliest of the islands, with more than 11 km of sandy beaches, several restaurants, a campsite and water sports. Boats leave from central Tavira and from the Quatro Águas quay. At its western end is Praia do Barril, reached on foot or by a small train from Pedras d'El Rei, with its anchor cemetery behind the beach.

Which Island Should You Choose?

Tips for Visiting the Islands
- Shade: there is little natural shade. Bring a parasol or rent one, plus a hat and sunscreen.
- Water and food: carry water, especially on Ilha Deserta, where there is only one restaurant.
- Last boat: missing the last ferry means an expensive water taxi. Check the time when you arrive.
- Season: ferries run all year, but there are fewer departures outside summer.
- Respect the dunes: stay on the boardwalks and paths, since the dunes protect the lagoon.
