The first reason why it wouldn’t be a good idea to visit the volcano is the U.V index. The U.V index is 43.3. ANd that is over the limit or max.
The Second reason why it wouldn’t be a good idea is because if you got there then you would fry up in minutes and you would a have a greater chance of getting skin cancer or diagnosed with something like that.
The final reason why is on December 29, 2003 The sun's ultraviolet radiation reached it’s limit and it was not safe.
That is why you should not visit Licancabur Volcano on December 29,2003.
