Lisbon Dolphin Watching Tour with Marine Biologist

Join a marine biologist to spot playful wild dolphins and aid ocean research

A small-group dolphin watching tour on the Tagus River and open sea near Lisbon, led by a marine biologist in partnership with Oceanário de Lisboa. The boat departs from the Oceanic Lounge, where you can relax and get a safety briefing before boarding. Your guide shares real cetacean research happening onboard, and the tour supports ocean monitoring data collection for marine conservation.

The experience

The tour starts at the Oceanic Lounge, where you have access to coffee, restrooms, and a safety briefing before you board. From there, the boat heads along the Tagus River and out to open sea on a modern vessel with an expert crew. A marine biologist guides the experience, explaining what you're seeing and how the data you're helping collect feeds into real cetacean monitoring work with Lisbon Oceanário and ICNF. The whole outing runs about three hours.

Dolphins are spotted on over 97% of departures in open water, though you might also see whales, seabirds, and other coastal wildlife depending on the day. As the boat turns back toward Lisbon, you get panoramic views of the city's landmarks from the river: a perspective most visitors never get. Sea jackets, water, and lifevests are provided. The boat is equipped with bathrooms and insurance covers the trip.

You choose between a private boat or a shared one at checkout. Both run the same route and include the same guide and marine research component. The difference is who else is aboard. The guide speaks English and Portuguese, and children are welcome from age 6 onward.

Is this one for you?Book the private boat if your group wants the dolphins and the research to themselves. Choose the shared boat if you're comfortable with other small groups and want to keep the price lower. Either way, you're on the water for three hours, so moderate fitness and comfort with boat movement matter more than which option you pick.
