Los Nietos train station is 5kms away with regular trains to the city of the fascinating roman city of Cartagena (2.70 euros return), Murcia, Madrid & beyond. The bus runs to neighbouring villages for local markets, Cartagena, Murcia & Alicante. Sheltered from the winds through the hills that surround it, Cartagena's deep water port has always been considered the best natural harbour in the Western Mediterranean. The entrance from the ocean is protected by rocky fortified headlands that act like claws, pincering enemy ships. With a fascinating history dating back 3,000 years, a walled city was built inside this perfect sea port.
