The Bagni Medusa in Genoa can be found on the Nerva promenade. It looks just like a balcony over the sea with a trattoria and pizzeria in the winter. It becomes a bathing centre during the summer months with an unusual, but natural, tidal swimming pool. The pool is actually a small basin formed out of rock jutting straight out of the sea. This is a very popular place with tourists where children in particular can enjoy playing in the warm waters.
