ECCO Ocean is the only licensed dolphin watching agency operation from Lisbon. It is a private and individual initiative led by a marine biologist that studies dolphins and whales. ECCO Ocean aims to assist ocean protection through scientific research, running on a strategy where its marine research is self-financed through ecotourism revenue.

ECCO Ocean ecotours are conducted on a sailing trimaran the #RVMegaptera, fast and under minimum engine use. The ecotours are mainly focused on dolphin watching expeditions that are its speciality and its main study subject. On these expeditions will be also possible to find seabirds and natural landscapes present in the Arrábida Nature Park.

The fauna and flora watching, including cetaceans and other marine animals, and snorkelling are its Natural.PT activities in Arrábida Nature Park.
