The hermitage clings to the cliff face of Monte Morrone, about 4 km northeast of Sulmona. It is a small complex of rock-cut chapels and cells, partly natural cave and partly built, perched on a ledge with vertiginous views over the Peligna Valley. The walk up from the abbey below takes 20-30 minutes on a stone path and is the most evocative part of the visit.
The site is associated with Pietro da Morrone, the ascetic hermit who became Pope Celestine V in 1294 and is now venerated as a saint. His cell, with its narrow stone bed, is the focus of the hermitage. Bring water and sturdy shoes; the path is uneven. The site is free and open most daylight hours.
