Cadena - Caribbean Coast

Cadena, off Costa Rica’s Caribbean coast, offers a different kind of dive. At a shallow 15 metres, it’s mostly a flat, sandy bottom with scatterings of rubble, not dramatic walls or massive coral heads. But that’s its charm. We’ve often spotted some intriguing bottom dwellers here – think speckled-tail flounders, smooth stargazers, and various snake eels camouflaging themselves in the sand. It’s a great spot for newer divers, or anyone who enjoys slowing down and really looking for the smaller, less obvious creatures. Visibility averages around seven metres, so it’s more about the macro life than wide-angle vistas.
