We had a lovely time on the water and a guide that was very knowledgable about the birds. This was a great way to get to know more about Lisbon and be outside. The boat and our guide, Carlos, made it a wonderful outing.

We had a great time on this boat tour with Carlos. He was friendly and knowledgeable, and was able to point out lots of different bird species to us, particularly some difficult to distinguish shorebirds. We highly recommend.

It was a very enjoyable tour. The guide knows where to find the birds based on the tides and he knows all their names in English. The species you see will depend on the time of year and tides. For the best birding experience, you can contact the guide in advance to see when the tides will be most favorable.

i had a great time and the trip was totally worth it as we have seen a lot of different birds - sandpipers, curlews, spoonbills, redshanks, marsh harriers and even an osprey with a fish the guide explained all the details and helped to timely identify the birds so we did not miss anything) I would love to come again to check this place at another time of the year

We went on a bird watching tour in late October. Carlos was a fantastic guide who really knew his stuff and where to find the birds. We got to see some fantastic species including Flamingo’s, Ospreys and Avocets. I really recommend this tour as the wildlife so close to Lisbon is amazing

We thoroughly enjoyed our estuary experience with Carlos on the boat, River Friends. It was such a nice change from city touring. There were so many birds! Flamingo, spoonbill cranes, osprey and several others. Carlos was very knowledgeable about the estuary and wildlife.
