The Karst Mountains and caves in Guilin are one of the few places on earth that show the beauty of huge, naturally forged Karst hills and caves. The limestone peaks poke out of the Li valley as if a child had drawn them. Taking in the views of verdant mountains while meandering down the Li River in a tour boat is a wonderful way to kick back and see a part of China that is very different from sprawling metropolis life in Beijing or Shanghai. thousands of people visit the site each year and attracting thousands more as the news of its beauty is being spread all over the world.
