Deiva Marina is a small Italian comune in the province of La Spezia, located about 65 kilometres east of the city of Genoa on the Riviera di Levante.
It is a quiet touristic resort, with clean seawater and a seashore surrounded by green mountains. It is known as a fishing place all year long.
Excursions to nearby Cinque Terre National Park, which is a UNESCO World Heritage Site, or to Portofino are very easy.
