Gruta do Centenário is the deepest cave of Brazil and of the whole southern hemisphere. It is located close to the summit of the 2,070 m 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.
