Praia de Alfarim

Sesimbra, Portugal

Lagoa de Albufeira is a unique coastal lagoon near Sesimbra where a freshwater lake meets the Atlantic Ocean, creating two distinctly different beach experiences in one location. For dog owners, the star attraction is the lagoon side — particularly the area known as Boca Velha — where calm, shallow freshwater waters provide a safe and gentle swimming environment for dogs of all sizes and swimming abilities. Unlike the Atlantic's powerful surf, the lagoon is tranquil and warm, making it ideal for puppies, elderly dogs, or breeds not comfortable in waves. Dogs are a common sight on the lagoon side year-round, though the official status is somewhat ambiguous — dogs are regularly seen and tolerated rather than formally designated. The ocean side of the lagoon features a dramatic Atlantic beach with serious surf, but the concessioned section may restrict dogs during the bathing season. The surrounding landscape is beautiful, with the lagoon ringed by low hills, pine forests, and Mediterranean scrubland. Facilities include free parking (limited spaces — arrive early), showers, restrooms, and restaurants nearby. Water sports equipment rental is available in summer. The lagoon sits 15 kilometres from Sesimbra and 36 kilometres from Lisbon, making it a popular weekend destination. For a truly special experience, visit when the sandbar between the lagoon and the ocean opens naturally, creating a flowing connection between fresh and salt water.
