What place in the world do you never want to visit? Why?

I’m curious and honestly, I would like to visit the whole world, but, thinking well, the depths of the sea and other underground areas, I prefer not to visit.
It gives me a strange feeling , in my mind…🤔 I’m not claustrophobic, in the past I’m gone walking in caves, but I don’t like….underground? Only under the city, yellow line, green, blue or red.😁
