This very impressive Seljuk-era mountain fortress covers the top of an idyllic wooded butte ringed by a curl of forested mountain. The brick rampart-ruins are relatively complete, with many photogenic towers, arches and wall sections calcified white with age or tufted with wild flowers. Access requires a steep, sweaty but gorgeous 50-minute walk starting out along a streamside full of mossy rocks then climbing pebble-studded concrete steps to the chorus of birdsong and tapping woodpeckers.
