The Parque Nacional da Chapada Diamantina (Chapada Diamantina National Park) is rather young. It was created in 1985 to protect the fragile eco systems of this area. For speleologists the sandstone and quartzite karst is the most famous feature of the park. But there are also karst caves in limestones with an abundance of speleothems, especially aragonite, gypsum and helictites.
Visitors to the park typically start at Lençois, a small village which was founded during the diamond rush after 1844. This diamond rush is the reason why this area is called Chapada Diamantina.
