# Lisbon: Dolphin Watching with a Marine Biologist - Ocean Safari

**Guidekin's take:** A fast rigid inflatable out of Lisbon into the Atlantic with a marine biologist leading the search for dolphins, lifejackets and a seat for everyone, at €65 per person for 2h 30m. Sightings are not guaranteed, and the ride is not for pregnant travellers or bad backs. 4.96 from 966 reviews.

In our comparison: #5 of 14 in Family Tours, by rating weighted by review volume (table below).

## Overview

Our main goal is to find dolphins! Depart from Lisbon on a fast Rigid Inflatable Boat (RIB). The adventure starts on a speedboat in search of dolphins as we head into the wide Atlantic Ocean. Get the best views of the Atlantic Coastline, on a comfortable and safe 8.5m RIB as we head out to sea.
We will scan the ocean in search of wildlife using several techniques; just like a scientist, you will play an important role in helping us find them. Get to know the different cetacean and seabirds species with an expert Marine Biologist. During 3 hours, you will experience the adventure of looking for wild marine species, like sunfish, sharks, jellyfish, whales or even sea turtles, so close to Lisbon. We want you to get to know them closer. Upon returning to the Tagus river, we will quickly stop in front of the beautiful monuments in Belem and you will admire the iconic 25th of April Bridge. Embark on this Odyssey of nature tourism with the true experts. The tour can be done in 2 boats.
