Connecting people with nature

A family business that grew up with the need to provide the possibility of nature lovers getting closer and connecting with wild species using high standards. Locally known the Tagus river, the wide Estuary, river mouth and the Lisbon Atlantic front are extremely biodiverse realms.

With the scientific knowledge on marine biodiversity and their resources, we intend to develop environmental awareness to a broader public. This can only be achieved by diversifying the Boat tours offer in Lisbon. The nature and cultural heritage is highly valued by motivating our guests to seek a comprehensive interest on these matters. We believe that, with an updated scientific knowledge, we can promote the Seas as a national designation.

We have a strong environmental awareness for the protection and preservation of natural resources. That’s why we adopted the concept of Nature Tourism. Lisbon sightseeing tours needed a differentiated outdoor activity that could offer diversified boat tours with professionalism. Therefore, Birdwatching in the Tagus Estuary, Dolphin Watching and Seabird Watching were developed to fulfil the demands. SeaEO also intends to collect sighting data for scientific research during the activities and with the help of the guests.

Departing from Doca de Santo Amaro, our daily boat tours, respect natures wildlife. All boat trips are done responsibly and include experienced crew, insurance, fees, fuel and life jacket.
