After safety instructions we set sale and even with the rough seas, they were mindful with people who could feel sea sick. Low Isles is fantastic and got to see turtles, fish, reef sharks. If people try to tell you to go to the quicksilver platform, dont. This is a much nicer and real tour, that really connects you to nature in a respectful way.”
