Serra de Montsant Natural Park, Natural park in Priorat region, Catalonia, Spain.

Serra de Montsant Natural Park protects 11,755.82 hectares of the Montsant range in the Priorat comarca, within the western Catalan Prelittoral chain. The Siurana and Montsant rivers enclose the massif, and the Roca Corbatera summit reaches 1,163 metres. The park spans nine municipalities, including La Morera de Montsant, Ulldemolins and Cornudella de Montsant.

The area served as a sanctuary for religious hermits during medieval times, leading to the establishment of the first Carthusian Priory on the Iberian Peninsula, Scala Dei. This monastic tradition shaped the region for centuries.

The mountain range holds deep spiritual meaning for local communities, reflected in numerous ancient monasteries and religious structures scattered throughout the park. These places shape the landscape today and draw visitors seeking contemplation.

Visitors can explore the park through a network of marked trails called 'graus', which provide access to central areas through natural passages in the cliff faces. Good footwear and water are important for longer walks on this rocky terrain.

Climbing has a long tradition in the Montsant range, and the rock here differs from the conglomerate of other Catalan crags, with many holes and fissures. Since the early 1990s sport climbing routes and via ferratas multiplied. A park commission with owners, climbers and the hiking federation divided the massif into free, conditioned and prohibited zones; in conditioned zones climbing is allowed from 15 July to 31 December.
