1. From Sesimbra: Arrábida Dolphin Watching Boat Tour
Look for bottlenose dolphins in the Sado Estuary on a scenic cruise from Sesimbra. Board the boat at Sesimbra Recreational Port, and then cruise along the Sado River towards Arrábida National Park. Look for the resident bottlenose dolphins in their natural habitat, along with common dolphins and dwarf whales. Interact with the delightful creatures as they feed, socialize and frolic in the water. Benefit from the services of an expert guide who will enlighten you about the marine environment and biodiversity of the shore. Learn about the geology and get information about local points of archaeological importance. If the weather conditions allow, and there is interest among the participants, stop in a strategic and sheltered place to swim in the calm and crystal-clear waters.
