Walk uphill for five kilometers, 1800 steps, to reach the Dyer Abbey on the top of the mountain on the north side of the ancient city. Although it is hard, the scenery along the way is good, and the observation deck is not far from the abbey. It is worth a trip to climb high. The monastery is a structure second only to Cazny in size, a shrine or royal tomb carved by Nahatians along the mountain, and was used as a monastery in Rome and Byzantine times.
