Key Facts

Mar Menor is a coastal saltwater lagoon located in the southeastern part of the Region of Murcia in Spain. Situated along the Mediterranean coast, this unique geographical feature is separated from the open sea by a 22-kilometre long sandbar called La Manga del Mar Menor, which creates one of Europe's largest saltwater lagoons. With a surface area of approximately 135 square kilometres and a maximum depth of around 7 metres, Mar Menor is renowned for its warm, calm waters that typically maintain temperatures several degrees higher than the adjacent Mediterranean Sea. The lagoon is surrounded by several municipalities including Cartagena, Los Alcázares, San Javier, and San Pedro del Pinatar, forming an important tourist destination known for its therapeutic mud baths and water sports. Due to its unique ecological characteristics, Mar Menor was designated as a Specially Protected Area of Mediterranean Importance and faces ongoing conservation challenges related to agricultural runoff and urban development pressures.
