“It was an amazing experience, we didn't see any dolphins unfortunately but being on a speedboat through the choppy waves was fun as hell. They also offered us to come back for free for another ride but we couldn't take it because of another tour. Couldn't recommend it enough, it was a lot of fun, even if you don't see any dolphins it's a great experience.”
