During the Carlist wars (to learn more click here) that took place in Spain during the 19th Century, the Carlists (followers of the autocratic monarchy) used a hidden place in the Sant Llorenc del Munt mountain range, now a Natural Park, to treat injured soldiers.

The Hospital de Sang is located in a huge cave resembling a tunnel, which straddles a large rock. To make the cave more comfortable, the soldiers built walls on both sides of it, and those ruins still exist today. During the 20th century it was used by woodcutters and coalmen.

The Carlists chose the place because it was large and hidden, there was a spring nearby (Font del Russinyol) and they could overlook the different ridges and ravines of the Obac range.

Near the Hospital de Sang, there is La Cort Fosca, a cave with a spring called del Russinyol 25m from the entrance.

We will also visit the Racó Gran rock shelter. Nearby there is another spring where wild boars go to drink, sorrounded by ancient stonework which has been restored.

We will climb to the Turó de la Pola (929m), the best viewpoint in the Sant Llorenc del Munt Natural Park.

If the group‘s fitness level is high enough, we will be able to reach the Quarto de Reixa, another cave that was used by shepherds to keep  their sheep until the late 1970s. It used to have an iron gate (reixa in Catalan means ‘iron gate’) that disappeared in the 1980s.

This circular hike is 6.3km long and will take us about 3 hours; the elevation gain is 420m.

This is a half-day hike
