The Derinkuyu underground city (Cappadocian Greek: Μαλακοπή Malakopi) is an ancient multi-level underground city in the Derinkuyu district in Nevşehir Province, Turkey, extending to a depth of approximately 60 metres (200 ft). It is large enough to have sheltered as many as 20,000 people together with their livestock and food stores. It is the largest excavated underground city in Turkey and is one of several underground complexes found throughout Cappadocia.

The lake basin formed as a result of volcanic activity; specifically it is classed as a maar lake. There is still geothermal activity in the area, which has given rise to hot springs around the lake. In recent years, the geothermal waters have been pumped up to nearby hotels for use in their hot baths. Lake Nar is particularly known for its scientific importance. It is home to a newly-described species of microscopic diatom algae called Clipeoparvus anatolicus. Nar lake waters undergo a remarkable change between different seasons. In winter, the lake water is cold from top to bottom. As the temperature increases in the spring, the lake water divides into an upper half which is warm (epilimnion), while the lower half (hypolimnion) stays cold and lacking in oxygen. An abundance of planktonic algae (or plankton bloom) in early summer changes the water chemistry and leads to the precipitation of calcium carbonate.

The canyon was formed in prehistoric times by the Melendiz Çayı. It lies between the villages of Ihlara in the southeast and Selime in the northwest. At the north end of the village of Ihlara, there is a stairway with almost 400 steps, which descends over 100 m down into the canyon. From the 7th century AD, the valley was settled by Byzantine monks who dug their houses and churches out of the tuff stone, which had been deposited by the eruptions of Mount Hasan. The earlier Greek name, Peristrema (Περιστρημα; winding round) of the village of Belisarma which is located about halfway along the valley from Ihlara to Selime, gave its name to the valley as well.

Selime Monastery is an astonishing rock-cut construction and the largest religious structure in the Cappadocia region with a cathedral-sized church cut directly into the volcanic tuff. Inside, original frescoes can be found although some have been damaged by weather. Signs of early civilizations are also present at the ancient site: Hittites, Persians, Romans, Early Christians, Byzantines, Seljuk Turks and Ottomans are some of the many inhabitants to have settled here. The church is separated into 3 sections by two rock columns. Kitchens and stables are also present as well as monks' living quarters which are adorned with time-worn frescoes. Selime Monastery is said to date back to the 8th or 9th century BC. The upper section mildly resembles a fortress with well-preserved walls and trenches as well as steep rock staircases and hidden passageways. In the 10th/11th century, the Monastery was converted to a Caravanserai, a refuge for travellers and tradesmen.

In the 2nd century AD there were ascetic monks who had adopted seclusion alone in the Cappadocia region, especially around Göreme. Although they were independent of monasteries and churches, they were an important social community. What made Cappadocia the centre of religious thought and life in the 3rd century was the presence of clergy with powerful character. In the following century, the region was known as the hometown of the three great clergy. These were the Bishop of Kaisareia, Basileios, his brother Gregorios of Nyssagia and Gregorios of Nazianus. Basileios, known as the ‘Great’, returned to his hometown, Kaisareia, the headquarters of the Cappadocia region, to devote himself to the monastic life. He was also effective in spreading the monastery life collectively.

The natural rock citadel of Uchisar Castle offers a panoramic view over the surrounding landscape of valleys, mountains, and towns. The tallest fairy chimney in Cappadocia is carved with numerous rooms, tunnels, stairs, rock tombs, and a large water cistern.

The Zelve Open-Air Museum, which once housed one of the largest communities in the region is an amazing cave town, honeycombed with dwellings, religious and secular chambers. Zelve is situated about 10 km out from Goreme on the Avanos road. Here, the Christians and Muslims lived together in perfect harmony, until 1924. Then Christians had to leave the Valley because of the exchange of minorities between Greece and Turkey, and the Muslims were forced to evacuate the Valley in the 50's when life became dangerous due to risk of erosion. They left the site to set up a modern village, a little further on, to which they gave the name Yeni Zelve (New Zelve).

Pasabag in Cappadocia is located on the road to Zelve, coming from Goreme or Avanos. Highly remarkable earth pillars can be seen here, in the middle of a vineyard, hence the name of the place which means: the Pacha's vineyard. Pacha means "General", the military rank, in Turkish and it is a very common nick name. This site is also called Monks Valley. The name was derived from some cones carved in tuff stones which stand apart. Currently, there is a vineyard and a number of tuff cones standing right next to the road. Some of these cones split into smaller cones in their upper sections, in which stylites and hermits once hid. The hermitage of Simeon monks was also here. A chapel dedicated to St. Simeon (Simon), and a hermit's shelter is built into one of the fairy chimneys with three heads. The entrance of the cell is decorated with antithetical crosses. Saint Simeon was living in seclusion near Aleppo in the 5th century, when rumours that he made miracles started to spread.

The old city of Avanos, whose name in ancient times was Venessa, overlooks the longest river of Turkey, the Kızılırmak (Red River), which also separates Avanos from the rest of Cappadocia.

Devrent Valley, which is also known as Imaginary Valley and also as Pink Valley does not have cave churches like the other valleys of Cappadocia. There are no Roman castles or Roman tombs in Devrent Valley, either. Actually it was never inhabited. So what makes it so famous? The lunar landscape! Devrent Valley (also spelled as Dervent Valley) reveals many different rock formations and is only a 10 minute drive from Goreme. The small fairy chimneys in the valley form a lunar landscape, or moonscape, by their strange look. The valley also has many animal shaped rocks. It looks like a sculpture zoo made by nature. Some of the most important, or the easiest seen animal shapes are camel, snake, seals, and dolphin. If you let your imagination run free you will find many others. It is like looking at clouds and seeing a dragon. There is even a rock pillar which looks like Virgin Mary, holding Jesus Christ.
