Chapada Diamantina (literally "Diamond Plateau") National Park is not nearly as famous as the coastal parts of Brazil. However, it's not less impressive. Deep inland, surrounded by table mountains, semi-deserts, canyons, gorges and ravines, the region hides one of the most beautiful caves in the world. Two of them - "Blue Pool" and "Enchanted Pool" - are filled with crystal clear, intensively blue waters. The other, "Torrinha Cave", one of the biggest and most impressive in Brazil boasts with huge chambers full of cave formations and to walk it through takes around 2 hours.
