About This Tour
During this unique experience we aim not only to observe the dolphins in their natural habitat but also to locate and collect floating plastic. It will thus be developing its environmental education as well as that of the smaller ones. Embark on Sesimbra and gain the opportunity to see other species (such as the common dolphin) as well as explore the entire coastline of the Arrábida Natural Park up to the Sado River. Its estuary is a point of prime importance for the conservation of dolphins, since they live there all year round, making this place a unique place considering that there are only three in all of Europe.
