Gruta do Centenário is the deepest cave of Brazil and of the whole southern hemisphere. It is located close to the summit of the 2,070m high Pico Alto do Inficcionado. But the most special thing with this cave is its geology: it is the deepest quartzite karst cave of the world! Quartzite is not really soluble by water, so quartzite caves are very rare, and such a big example is really extraordinary.
This cave is not accessible to tourists. Beneath its remote location, which includes a 6 hours hike from the Santuário do Caraça up the Pico Alto do Inficcionado this cave is a vertical cave and only suitable for experienced cavers.
