Cappadocia has dozens of underground settlements, but most tours visit either Derinkuyu or Kaymakli. Knowing the layout differences helps you choose the safest option if you dislike enclosed spaces.
Which underground city to visit?
Choose Derinkuyu for maximum depth, or Kaymakli for wider walkways.
Derinkuyu requires navigating very low, narrow tunnels. It is the deepest known underground city in the region. Kaymakli spreads out more horizontally, which feels less restrictive. If you have severe claustrophobia, bad backs, or mobility issues, Derinkuyu is not recommended.
How deep is Derinkuyu underground city?
Derinkuyu plunges 85 meters down into the volcanic rock.
The public can currently access 8 illuminated levels. A 55-meter deep central ventilation shaft reaches all the way to the bottom. This shaft provided fresh air and functioned as a water well for the estimated 20,000 people who sheltered here.
Is Derinkuyu safe for claustrophobia?
No, Derinkuyu is not recommended for those with severe claustrophobia.
The site requires navigating very low, narrow tunnels. You will often need to crouch to move between levels. If you want a slightly more open feel, Kaymakli is the better alternative.
