It is the only way on this site to see the underwater world with no swimming at all, which makes it the pick for grandparents, young children and anyone who does not want to snorkel. The try dive for beginners goes deeper into the experience, with a mask and an instructor, but it rules out under-8s and some health conditions.
It is also short, so it pairs well with a lunch in the marina or an afternoon on the beach.
With up to seven dives a day, it is also easy to fit around other plans. The audio guide covers ten languages, including Dutch, Finnish, Norwegian, Polish and Czech as well as English, Spanish, French, German and Italian, which helps mixed groups. Cancellation is free up to 24 hours before.
