CAT’s Lencois tours take you to this well preserved colonial town in the northern region of Brazil. The town was founded in the 18th century when diamonds were first discovered in the area. However, diamond mining has been prohibited for some time in order to protect the natural habitats of the area, and the principal industry is now coffee growing. The town is also the main entrance to the Chapada Diamantina National Park, an area of beautiful deep valleys and high mountains. This grand landscape is very popular trekking terrain. Class Adventure Travel offers visits to the town and Chapada Diamantina trekking tours.
