Puerto Banús, located at the water's edge, is the perfect place for an aquarium. It is in the Control Tower of the port. The little ones will have a ball with the "underwater baptism," diving into a 3m-deep tank - always under supervision of an instructor - and surrounded by fantastic species: ray-fish, lobsters, eels, and small sharks. They can pet and feed the well-behaved rays, also known as "sea puppies." They will then receive a diploma that certifies that they are little versions of Jacques Cousteau.
