An UNESCO-site located just south of Baku, capital city of Azerbaijan, Qobustan has several culturally and naturally valuable sites. The mud volcanoes are popular because of the health benefits of bathing in them and because of their fascinating appearances. They also come to good use for researchers, whom with the help of mud volcanoes for example can predict the sizes of for example underground gas deposits.
