Lençóis is a small city in Bahia, Brazil. The city is very charming with cobblestone streets and many wonderful hole in the wall restaurants.
Lençóis serves as a "base camp" of sorts for tourists from all over the world setting out to explore the Chapada Diamantina National Park.
Since Lençóis is a small, you can walk anywhere around town. To get out of town to see the sights in the Chapada Diamantina, book a tour and they provide transportation and guide. There are some waterfalls, swimming holes and natural slides on the outskirts of Lencois all at a walking distance.
Other than that the main attraction of Lencois the town serves as a good base for trekking trips into Chapada Diamantina National Park. There are day trips as well as longer treks of up to 5 days. The trips can be organized with a tour agency which takes care of everything including transport, guide food etc., but you can also buy a map of the park and venture out on your own.
It is a wonderful experience being in that wilderness and if possible dont try to skimp on it even though it can be a bit expensive. The experience is every penny worth it. The roads outside Lençóis are full of pot holes. Be prepared for a bumpy ride when you leave the town to go on tours.
