Pigeon Valley is worth visiting for both the viewpoint and the history behind the rock-cut dovecotes. The small openings in the cliffs were used for pigeons, whose droppings helped fertilise local vineyards and orchards.I visited from the Uçhisar side. The viewpoint works well as a short stop, while the full trail to Göreme is about 4.1 km. According to the official sign, the average walking time is around 3.5 hours. The path is narrow and uneven, with steep sections and some risk of falling rocks, so proper walking shoes, water and sun protection are important.A very interesting place once you know what the holes in the cliffs were actually used for.
