★★★★★★★★★★4.0 · 3,019 reviews · from $38Our pick

Cruise from Estação Fluvial Sul e Sueste past Lisbon’s landmarks and out toward the Atlantic in search of wild dolphins. Guides such as Anna, Barbara, and Telma add local stories and marine insight. The $38 fare includes a 2.5-hour cruise and open bar, but dolphin sightings are never guaranteed.

“everything was well organised. the meeting point and the whole experience in general. the beer and sangria was EXCELLENT!! The staff were friendly and professional (max 2 people outside at the front of the boat for example) would have been great to see dolphins but again we know they are wild animals so there is no guarantee. we appreciate the effort that the crew made to try and find them for us. overall, it's an activity that we would do again.”

Our biologist provided clear and interesting information about dolphins and their habitat around Lisbon. Note the boat has saddles that the passengers straddle; skirts are not a good choice for this trip.”

By coincidence we were the only 2 people who booked the tour but still got to go and got to see many dolphins. Even a few ones with baby! They came very close to the boat and even when we headed to a nice place to take a dive, we had a second round of dolphin watching. The tour guides were really nice and chill with us being the only ones. During the tour we also got a regional drink and pastry which was perfect when you have already…”
