The Cilehane is a narrow cave passage about a kilometre from the main complex, traditionally used as a place of spiritual retreat and absolution. Pilgrims crawl through the tight underground passage on hands and knees — the symbolism is of passing through a kind of rebirth. Whether the passage is accessible depends on who is attending, and whether you can fit through it depends on the width of your shoulders and the weight of your coat.
The surrounding landscape is open and rocky, with views across the plateau. The approach through small gardens and orchards is pleasant. In August, during the annual Hacıbektaş commemoration, the entire area around the complex and the cilehane fills with pilgrims, musicians playing the saz, and cem ceremonies — making it one of the more vivid religious gatherings in Turkey. At quieter times, the atmosphere here is meditative.
