A few kicks with your legs and you glide a little closer to the large, white sea anemone, whose tentacles sway gently in the current. Is that the orange face of a clownfish peeking out? Yes, there's the little guy, paddling cheerfully with his fins and seeming to eye you as curiously as you eye him. You are swimming just below the surface of the water, equipped with diving goggles and a snorkel. Sunbeams dance around you, a message from the world above the water, which is no less fantastic than this ocean paradise. You are in the eastern Caribbean, on the dream island of Barbados.
