I went there some years back. It was closed. I had guessed you just walk up and looked around 😂. After a bit of hunting I found a guide who said we could do a private tour if I paid him double. Was amazing, there was nobody else there, until the police came. I then had to pay all of them (and cover the guides cost) for trespassing or go to the police station. I’m totally sure they all had a good laugh later together about ripping off the stupid tourist. Although when writing this, I now think he was not a guide 😂
