Toca da Boa Vista is still said to be the longest cave of the southern hemisphere, and the longest cave of Brazil. The longest cave of Brazil is still true , but the longest cave of the southern hemisphere is the Bullita Cave System (Burke's Back Yard) in Australia  The longest cave list changes frequently, when new passages are explored and mapped, so most of those "facts" told on cave tours are outdated. On the other hand, a cave with 114 km of passage is definitely impressive.
However, most famous is this cave for an enormous amount of prehistoric bones, which were found in the cave. 20,000 years ago an enormous river transported dead animals into the cave, which formed massive deposits of bones. More than 50,000 bones have be excavated until now, among them the bones of huge mammals which are now extinct. An example is a 6 m long giant sloth.
Its rural and isolated location has prevented it from becoming a tourist spot, and it remains an important area of immense scientific value. The cave has numerous entrances, but all are vertical drops and require climbing gear. The cave is very dangerous as it is hot and very dry. Many cavers have problems taking enough water with them. Dont try to enter it. The coordinates given on Wikipedia are wrong though, so you will not be able to find it.
