Mercurius - Fernando de Noronha
Dropping in at Mercurius, you're usually met with a gentle drift along a volcanic reef. We've often spotted green sea turtles munching on algae, and the occasional lemon shark cruising by. It’s a pretty relaxed dive, good for shaking off the rust or just enjoying the typical Noronha scene without too much fuss. Visibility here tends to be consistently good, making it easy to just soak it all in.
