Leave from the port of Abrigo de Sesimbra to observe dolphins in their natural surroundings. Get a chance to watch Bottlenose Dolphins and Common Dolphins in the clear blue seas of the Arrábida Natural Park, while respecting their native behaviour. Alongside you will be a marine biologist, keen to share interesting facts about these amazing creatures, such as their diet, commonplace behaviours and group interactions. Other wildlife, including various types of birds, will also be observable. Once observation concludes, you’ll have the opportunity to swim and soak up the sun on one of Portugal’s loveliest beaches or bays, only reachable by sea. You can also explore caves and rocky structures along the coast of the natural park and listen to the intriguing tales from the 18th century that define this area, narrated by your local guide.
