Enjoy a boat tour with dolphin observation through Arrábida coast, with boarding in Sesimbra. Observe more than one species of dolphin if you are lucky, like common dolphin and roazes corvineiros. Watch the cetaceans in their own natural habitat, as they socialize, swim, and eat. Experience an educational component about sea living and biodiversity, and the geology and points of interest of archeological and historical importance connected with this region. Travel along Arrábida coast, passing through the caves and sacred beaches protected by cliffs with transparent and crystalline water if the dolphin observation happens early in the tour. Stop for diving and swimming if the weather and sea conditions are favorable.

This full-day tour begins as you head south from Lisbon to Setúbal, a picturesque region best known for its fishing port. In Setúbal, board a fully restored salt galleon, or a modern catamaran (depending on weather and sea conditions), for a relaxing and enjoyable cruise in the Sado Estuary, where you’ll learn about the resident bottlenose dolphins and hopefully be able to observe wild dolphins in their natural environment. The duration of the cruise takes about 2 to 3 hours. See the natural reserve of Arrábida, take in the stunning views, and learn about the area’s history and gastronomy. See the Arrábida Convent and discover some important historical sites before returning to the old city center of Setúbal. Before returning to Lisbon, stop at a few sights in the Arrabida Mountain range, from where you can marvel at the natural reserve and get a land view of all the region.
