Deservedly known as the "deserted island", Barreta is a narrow 7 km long sandbank off the coast of Faro. It is in fact the closest of a number of sandy islands that make up this stretch of coast. Forming part of the Ria Formosa National Park, this is one of the best destinations for those wishing to escape the crowds and experience the remote calm of an undeveloped wilderness.

Located a few kilometres northwest of Sagres is the historic Cabo de São Vicente (Cape of Saint Vincent) is a craggy, windswept headland at the spot which claims to be the most south-westerly point of mainland Europe. Until the end of the 14th century many believed this place to be the end of the world - come here on the right day and you might think they had a point. The Romans called this place the Sacred Promontory, and if you stand here at sunset, it can be easy to see why - the sun appears unusually large as it descends over the seemingly endless sea. 

Literally translated, Boca do Inferno means the "Mouth of Hell". Whether this coastal rock formation near Cascais actually lives up to its name largely depends on the sea conditions. On a calm, sunny day it can be positively idyllic, however, when the full fury of an Atlantic storm is thrown this way the display can be awe-inspiring.

Boca do Inferno is located on the western edge of Cascais, around from the Santa Marta lighthouse. It is easily reachable from the town on foot but there is also plenty of parking here (and a restaurant) if you are driving.

Located around 10 km (6 miles) off the coast of Peniche is the rugged Berlengas Archipelago. This collection of 3 little islands, named Estelas, Farilhões and Berlenga, is virtually uninhabited, well, except for about a million seabirds! Now a nature reserve (Reserva Natural das Berlengas) these islands are home to puffins, seagulls and cormorants and they are very much in charge these days. Not only are the three square kilometres of island protected but so are the surrounding seas which make up a 985 hectare marine reserve.

The Ria Formosa estuary forms a complex of lagoons,marshes and salty areas. The park which extends 60Km along the coast provides habitats to a wide range of wildlife

One of the finest stretches of protected coast in Europe. Over 100 km of natural habitat from Porto Covo in the Alentejo, to Burgau in the Algarve

The sea cliffs on the western edge of Lagos create the fantastical rock formation of Ponta da Piedade. Access to this ensemble of grottoes and sea arches is via hundreds of steps cut into the cliffs. However, the best way to appreciate it is by boat.

Also known as the Promontorium Sacrum (sacred promontory), Sagres Point is both geographically and historically significant. Once considered the end of the known world by many it is in fact neither the most westerly or southerly point of Portugal (and therefore continental Europe). However, it can be considered the most southwestern-most point and it certainly maintains a feel of being the end of the world.
