Exploring the waters off Lagos with a dolphin and cave tour often promises more than just pretty scenery. This particular experience, offered by Seatrips Lagos, combines the thrill of spotting wild dolphins with the awe of visiting Portugal’s famous Benagil Cave—all in one 2.5-hour trip. What makes this trip stand out is the presence of marine biologists on board, who enrich the experience with expert insights into local wildlife and the ocean environment.
Two things I really appreciate about this tour: first, the focus on wildlife conservation—the vessel is “dolphin friendly,” thanks to modern hydrojet propulsion that minimizes harm to these majestic creatures. Second, the expert guides make a difference. Reviewers especially mention guides like Adriana, whose knowledge and friendly approach turn a boat ride into an educational journey. The only potential drawback? Since dolphins are wild animals, there’s no guarantee of sighting them—though, with a success rate of about 98%, you’ll likely have plenty of close encounters.
Despite the high success rate, some travelers might wish for a more customized experience or longer dolphin sightings. Nonetheless, given the boat’s speed, safety features, and the skill of the guides, most find it excellent value, especially considering the combined experience of marine life watching and the visit to the stunning coast and caves.
