The 4×4 tours show you the edge of the Lençóis; the trek on foot hands you the heart. Walking for 2 to 4 days across a sea of dunes, swimming in lagoons no vehicle reaches and sleeping in inhabited oases — islands of vegetation where half a dozen families live raising goats between nowhere and nowhere — is one of the great Brazilian adventures. Here is the complete guide to the experience (the park in general is covered here).
How it works
The classic route crosses the park from Santo Amaro to Atins (or the reverse), with nights at the oases of Queimada dos Britos and Baixa Grande — sleeping in hammocks or simple rooms in the residents’ houses, with a dinner of free-range chicken and dried fish by lamplight. You walk 15-25 km a day, always at dawn and late afternoon (from 10am to 3pm the desert is an oven), with a native guide finding the way between the lagoons. Entry to the trek is only permitted with an accredited guide, and the 2026 ICMBio rules require advance booking at the support points (Atins, Baixa Grande, Queimada dos Britos and Betânia) and limit groups to 10 people per guide — see the official rules for the crossing (checked in August 2026).

Preparation and pack
- Fitness: walking on soft sand is twice as tiring as tarmac — but the terrain is flat and the lagoons break up the effort. If you can walk 10 km comfortably, you can do this.
- Feet: the crossing is done BAREFOOT or in sandals — sand gets into any trainer. Protect the top of your feet from the sun (that is the classic burn).
- Minimum pack: 5-7 kg — swimwear, one dry change of clothes, hat, sunscreen (applied well away from the lagoons), water bottle, flashlight and cash for the oasis families.
- Mindset: no signal, no power beyond the generator at dinner, no hurry. It is the detox you pretended you did not need.
Why the crossing matters
The oasis families used to live off cattle and isolation; the trek brought an income that keeps the young people on their land and turns every resident into a guardian of the park. Staying at Queimada dos Britos is ecotourism in its rawest form: your dinner funds the people who stop the desert becoming a cattle farm. And sleeping to the sound of the wind on the dunes, under a Milky Way with no electric competition, settles any doubt about whether it was worth it.
🥾 Who is it for?
Effort: intense — 30+ km over 2-3 days on soft sand under the sun, with nights in oases. Children: not recommended before age 14. Older travelers and people with reduced mobility: only with excellent fitness; for everyone else, the 4×4 circuits show the Lençóis without the crossing.
