Ilha de Tavira
Sandy islands (all part of the Parque Natural da Ria Formosa) stretch along the coast from Cacela Velha to just west of Faro, and this is one of the finest. Made up of dunes, gently shelving sand and a strip of woodland, this is the Algrave at its best, a real hideaway only reachable by boat.
Parque Natural da Serra da Estrela
Fascinating for its natural and cultural history, Parque Natural da Serra da Estrela was one of Portugal’s first designated parks, and at 888 sq km remains the country’s largest protected area. The rugged boulder-strewn meadows and icy lakes of its high country form one of Portugal’s most distinct and unexpected landscapes.
