Opi's most striking feature is the village itself, seen from below. The classic view is from the SS83 as you approach from the direction of Pescasseroli: a tight cluster of stone and plaster houses sitting on a narrow rocky promontory, mountains rising behind, the Sangro valley dropping away on either side. It is the kind of scene that looks arranged for a photograph but is entirely real.
Walk to the western edge of the village, past the church, and you reach the point known as La Foce — a narrow gorge where the oldest houses perch right on the cliff edge. From here the views across to Monte Amaro, Monte Irto, and Monte Marsicano are superb, particularly in the late afternoon light. Opi earned its Orange Flag from the Italian Touring Club largely on the strength of this setting, and it is easy to see why.
