A singular geological and mining experience

In Central Catalonia there is one of the largest potassium deposits of Europe. It emerged about 37 million years ago during the formation of the Pyrenees and consists mainly of salt. The remarkable geological diversity of the area helped shape the local activity throughout the years. It has resulted in many underground passages, roads, miner’s huts and outcrops that now have a great touristic, educational and scientific interest. That is the reason why the Parc Geològic i Miner de la Catalunya Central (Geological and Mining Park of Central Catalonia) was created this past May.



The park aims to explain the characteristics of this landscape full of caves and deposits of salt and gypsum. In other words, it helps interpret and understand the geological history of this area and that of those who have lived here over the centuries.

On your visit, you can choose among 46 points of interest. Exceptional sites like the Coves del Toll (Caves of Toll), the Coves del Salnitre (Caves of Salitre) or the ancient deltas of Montserrat and Sant Llorenç del Munt. It’s good to remember that this mining area has become a worldwide reference when it comes to marine evaporites with minerals such as halite (regular salt), and sylvite (potash).

The Mountain of Montserrat

In the park, you will find several routes that will satisfy your geological curiosity, designed to move you around the neighboring area. One of the routes begins in the Cuevas de Salitre, in the town of Collbató and takes you to the Museo de Geología y La Cueva, in the town of Manresa, makes a stop in Calders where you can see a kiln and ends in the town of Moià, right at the Cuevas del Toll.
