It was nice and welcoming guys who welcomed. Nice trip where we saw a lot of dolphins and they came very close to the boat. Nice that the boats are not so big and the groups are small.

What an adventure indeed! If you happen to be around Cascais I would 10000% recommend that you do this boating trip! The guys were super amazing and enthusiastic and got us to see a massive pod of dolphins! There must have been more than 100 around us! We even got to see a few baby dolphins. This is by far one of the best experiences that we’ve done! Cannot stop talking about this to my family and friends!!! Que aventura incrível! Se estiver por Cascais, eu recomendo 10000% que fizesse este passeio de barco! Os rapazes foram super incríveis e entusiasmados e nos levaram para ver um enorme grupo de golfinhos! Devia haver mais de 100 ao nosso redor! Ainda tivemos a sorte de ver alguns filhotes de golfinhos. Esta é, de longe, uma das melhores experiências que já tivemos! Não consigo parar de falar sobre isso com minha família e amigos!!!

This was one of the highlights of our stay in Cascais . We saw so many dolphins - larger bottle nose and a smaller variety- they swim very close to the boat providing a wonderful dolphin watching experience. The crew were friendly and we would highly recommend this tour with four adventures. Thank you !

Amazing trip. Worth every Euro. Very friendly, very safe (weather was calm…glad that we went in the morning (9.00), as it is usually more windy later). Do this if you love Nature! The team told they cooperated with other fishermen and tour boats, so we were not disappointed: Saw the first two after 15 minutes, but then sailed for 45 minutes towards Cabo da Roca to go were a whole steam (maybe 10 dolphins) had a good time to our great pleasure. At the end of our trip: A short exciting speedy ride in calm waters. So much fun for everybody. Would love to post a photo, but I only have about 10 videos of dolphins (which I cannot post)
