The butter-coloured beaches for which the Algarve is famous are within easy reach of Albufeira, a popular holiday resort that boasts a vibrant nightlife scene. Exploring the Atlantic by boat is one of the top things to do in Albufeira, as is searching for bottlenose dolphins and admiring the dramatic cliffs that dominate the coastline. The Benagil Cave is most photogenic—the swirling sandstone structure is reminiscent of a Dali painting. After a day at sea, visitors with a taste for glamor head to nearby Vilamoura, a marina famed for its high-end restaurants and sleek yachts.
