Los Nietos, Spain is a small fishing village with its own individual marina on the Mar Menor, which began as a very small fishing settlement and was later urbanised to allow more holiday homes by the Mar Menor. It is now a busy community with many visitors, especially in the summer, with some events at other times. Many foreigners, mainly British, live there. The village is at the eastern terminus of the Cartagena-Los Nietos commuter railway line.
