Catalan Mediterranean System

The Catalan Mediterranean System is a system of mountain ranges that runs for a length of 250 kilometres parallel to the coast of the Mediterranean Sea, in the Catalan provinces of Tarragona, Barcelona and Girona.

It consists of three sub-systems: the Cordillera Litoral, the Cordillera Prelitoral and the Cordillerra Transversal.

The Cordillera Liitoral is located directly on the Mediterranean Sea, is about 100 kilometres long and has peaks of about 600 metres. It consists of the following sub-mountain ranges: Macizo del Montgrí, Montañas de Begur, Macizo de les Gavarres, Macizo de les Cadiretes, Sierra del Montnegre, Sierra del Corredor, Sierra de Sant Mateu, Sierra de la Marina, Sierra de la Collserola, Montaña del Montjuic, Macizo del Garraf and Macizo del Montsià.

The Cordillera Prelitoral is the part that is further inland and is considerably higher than the Cordillera Litoral, with an altitude of just over 1,700 metres in the Macizo del Montseny. Other sub-mountain ranges in this sub-system are the Sierra de Guillerías, San Llorenç del Munt, Sierra de Montserrat, Montañas de Prades and the Sierra del Montsant. It has a length of approximately 250 kilometres.

La Cordillera Transversal is located in the transition area between the Cordillera Prelitoral and the Prepyrenees , and is known for its volcanic activity, with the following areas: Parque Natural de la zona volcánica de La Garrocha, Volcán de Santa Margarita and the Volcán de Croscat.

In the east, the Catalan Mediterranean System merges into the Valley of the Ebro and further to the southeast into the Iberian System. In the transition area between the Catalan Mediterranean System and the Iberian System, in the province of Tarragona, we find the Parc Natural dels Ports.
