Derinkuyu Underground City
Most Green Tours go to Derinkuyu, the deepest excavated underground city in Turkey. It reaches about 85 meters (280 ft) down, with 8 of an estimated 18 levels open to visitors, and was large enough to shelter as many as 20,000 people with their livestock and food. Passages are narrow, low and steep in places, and it stays around 13–15°C (55–59°F) year-round, so bring a layer.
Derinkuyu or Kaymaklı? Some tours substitute Kaymaklı, about 25 minutes from Göreme. It's wider and shallower, and easier if tight spaces bother you; Derinkuyu is deeper and more dramatic. Check which one your listing names.
Ihlara Valley walk
Ihlara is a canyon about 15 km long and up to 150 m deep, cut by the Melendiz River, with more than 100 rock-cut churches in its walls. Tours don't walk the whole thing: the usual stretch is 3–4 km, about 1–1.5 hours, from the Tourist Gate to Belisırma village. The path itself is flat and easy. The effort is the staircase of roughly 400 steps down into the canyon. Lunch is usually at Belisırma, at restaurants on platforms over the river.
Selime Monastery
Selime is the largest rock-cut religious complex in Cappadocia, a monastery carved into the cliff at the northern end of the Ihlara valley. Reaching the upper rooms is a short scramble.
Some itineraries add the Göreme Panorama viewpoint, Pigeon Valley or Nar crater lake. Most include one sales stop, usually an onyx or jewelry workshop.
Is the Green Tour worth it?
Yes, and it's the stronger of the two cases for joining a tour. Its sights are far from Göreme and from each other, so recreating the day without a car means long, awkward transfers. If you're already exploring Göreme, Uçhisar and the central valleys on foot, Green also adds experiences you won't come across by walking around central Cappadocia.
