Marina & Náutica Marlin (Grupo CubaSol SA)

Marina & Náutica Marlin sits on the waters of Cienfuegos Bay, offering round-the-clock operations with security, fuel services, oil disposal, showers, and solid scuba diving right on site. The staff here regularly earns praise by name — the kind of place where you'll actually feel looked after rather than just processed. It's a rare find in Cuba for anyone arriving by sea, with all the basics covered and a dive scene worth coming back for.
