The Ria Formosa is a protected natural park and coastal lagoon that runs along the eastern Algarve, sheltered from the Atlantic by a chain of low barrier islands and sandbars. Its maze of tidal channels, salt marshes and mudflats is an important place for birds, and shorebirds, waders and flamingos can be seen here, especially outside the height of summer. For visitors, the easiest way to see it is a boat trip from Faro, where operators run small-group cruises through the lagoon to the islands, with stops on sandy beaches and at fishing villages that have no cars. The trip on offer here is a roughly three-hour cruise by Islands 4 You from Faro, with a 4.9 rating from more than 1,500 reviews on Viator, and it visits several of the islands of the park. Other operators run sunset cruises, eco-boat trips on a solar-powered vessel and private charters, and some tours start from nearby Olhão. The lagoon is shallow and gentle, so it suits families and anyone who finds the open-sea caves of the western Algarve too rough or too crowded. It also gives a quiet counterpoint to the resort coast, with a very different pace and landscape.
The islands: the barrier islands include Ilha Deserta, also called Barreta, which is often described as the southernmost point of mainland Portugal and has long empty beaches; Culatra, with its two fishing villages; Farol, with its lighthouse and a small village; and Armona, further east. Most of the islands are car-free and reached only by boat, so a guided trip is a convenient way to see several in one outing. Facilities are limited, so a stop for lunch or a swim is usually part of the plan.
Nature and manners: the park protects fragile dunes and nesting grounds, so keep to marked paths on the islands and do not disturb the birds. Bring binoculars if you have them, sunscreen, a hat and water. Tides shape the schedule, so operators set departures around them, and trips can be rescheduled in strong wind.
Fitting it in: because Faro is the airport city, a Ria Formosa cruise is an easy first or last day, and it is easy to combine with a walk around Faro old town and the marina. In shoulder season and winter, the quieter light and the birdlife can make it more atmospheric than in the height of summer.
