Inland Algarve holds nature reserves, medieval castles, and Roman ruins that together form a wide picture of Portuguese history and nature. Monchique has thermal springs, Silves shows a castle built of red sandstone, and Faro contains a chapel lined with human bones. Natural parks like Ria Formosa provide habitat for many bird species, while historic villages, coastal fortresses, and lighthouses mark the landscape. Travelers through this region encounter places like Cabo de São Vicente, where land ends at the southwestern tip of Europe, the cliffs of Ponta da Piedade near Lagos, or the ruins of Paderne Castle. Caldas de Monchique invites bathing in warm spring water, the Percurso dos Sete Vales Suspensos follows the coast through cut valleys, and Igreja do Carmo in Faro holds another bone chapel. Between these are beaches like Praia da Marinha and Praia do Barril, Roman excavations such as Cerro da Vila in Quarteira, and Palácio de Estoi, a pink palace from the 19th century. The Algarve connects coast and interior, history and nature in a way best explored on foot.
