Caverna Ouro Grosso
Massive Gold Cave
Useful Information
History
Description
Caverna Ouro Grosso is definitely a wild cave.
It seems it is the location of spelunking tours but they are only for physically
fit and not too big participants, as the entrance is very low.
Arachnophobia will also disqualify you, as the narrow entratrance is the home of
numerous cave spiders - which are protected, of course.
A visit of this river cave takes at least four hours, but there are also tours
of six to eight hours.
Neoprene is a very good idea.
