This would be a better experience if there weren't so many other people wanting to see this amazing underground city of 8 levels at the same time as you!!! There is a sign outside saying it is not suitable for people with claustrophobia, heart conditions or asthma. But even if you are not suffering from any of these conditions, it can be a challenge as some of the time you are walking along very narrow tunnels bent at a 90 degree angle so as not to hit your head, and with your shoulders touching both walls. Climbing back out is also difficult as there is nowhere to rest and you just have to keep going. Wear sports shoes and be prepared for the physical challenges.
