Praia da Duquesa is a beach that lies between two seafront mansions – the Chalet Faial and the Chalet Palmela. It has long been associated with royalty as its name honors the Duchess of Palmela, who lived in the mansion above. Praia da Duquesa provides visitors with crystal-clear waters perfect for swimming, paddling, and simply taking relaxing walks along its coastline. Available nearby are restaurants and bars, and visitors can take a 15 minute stroll towards Estoril if they're looking to explore nearby beaches. This hidden beauty is worth the short train ride from Lisbon – make sure you don't miss it!
