Derinkuyu is Cappadocia's biggest underground with approximately 7 floors and 85m deep. It contains all the usual rooms found in an underground city (stables, cellars, storage rooms, refectories, churches, wineries etc). Apart from these, a large room with a barrel vaulted ceiling on the second floor was a missionary school, the rooms to the left being study rooms. From the 3rd and 4th floors onwards the descent is by way of vertical staircases, which lead to a cruciform plan church on the lowest floor. The 55m deep ventilation shaft was also used as a well. Not every floor was provided with surface access in order to protect the dwellers from poisoning during raids. Derinkuyu underground city was opened to visitors in 1965 but so far only 10% can be visited.
Early Christians have constructed their rock houses and temples by carving the tuffs in the valley of Ihlara, through the valley runs the Melendiz River. The waters of the river are named Ihlara as Peristrema meaning "The people of circulating waters". To search the source of the water in Ihlara, is in fact trying to reveal the meaning of life. It takes 2 1/2hrs to walk from the Ihlara Vadisi to Belisirma and about 3hrs to walk from Belisirma to Selime.
The magnificent landscape around Goreme has been formed from its solidified lava streams, its ash and tuff stone, all dating from the Neocene period. A result of thousands of years of continual erosion makes this area look like a lunar landscape. The fairy chimneys also have a great colour variety. There are light and dark colors from white to yellow, pink, grey and black.
