The Croscat Volcano Natural Reserve: A Journey Inside a Volcano

In the heart of la Garrotxa, the Croscat volcano stands as a majestic testament to Earth’s dynamism. This volcano, one of the most iconic on the peninsula and the largest, offers a unique opportunity to explore the geology and biodiversity that characterize the Garrotxa Volcanic Zone Natural Park.

Croscat’s most distinctive feature is its shape, the result of past mining activities that have left an open scar, but also allowed the exposure of fascinating layers of clay and other volcanic materials, providing visitors with an unparalleled view of a volcano’s internal structure.

You can access the quarry area on foot from Can Passavent, the park’s information center, or by tourist train. Without the vegetation covering the rest of the volcano, you can observe the hypnotic beauty of the overlapping layers of gray and black lapilli, which change to their characteristic reddish-orange color with oxidation.

Due to its uniqueness, access to the Croscat Volcano Museum Space is specially regulated for organized groups. Access requires prior reservation and must be accompanied by a guide certified as a Good Connoisseur of Garrotxa (you can check the associated guide companies). This measure ensures that visitors enjoy the best experience and helps preserve this impressive volcanic landscape.
