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.
