About Fundão + Vinte e Um.

This is considered one of the hardest treks in the Chapada Diamantina, and it is recommended for very experienced hikers only. It follows a little-walked route through the National Park — genuinely inhospitable and isolated.

The route climbs the Fundão Canyon along the riverbed to Fundão Waterfall, and from there tackles a very difficult stretch to reach the Vinte e Um canyon, where camp faces walls of around 80 metres.

There are two formats of the same route: 18 km over 2 days with one night of camping, or up to 24 km over 3 days with two nights and Fumaça Waterfall seen head-on along the way. It can be combined with Fumaça 360°, Fumaça from Below or the Mixila — ask us about availability.

Where we sleep

In tents or by the river, on sleeping mats and in sleeping bags rated for the temperature — all provided. Weather permitting, you can sleep outside the tent, with the sound of the river and a sky full of stars.

Breakfast and dinner

Prepared at base camp by the local guide, with a menu that varies. Tell us about dietary restrictions when booking.

2 or 3 days

Day 1
Fundão Canyon + Vinte e Um Waterfall
8 kmExtreme
Departure around 6:00 am on the trail linking Lençóis to Vale do Capão. Where the Ribeirão meets the Fundão river, we head upstream through the Fundão Canyon — around 3.5 hours of walking to Fundão Waterfall. After the snack prepared by the guide, we climb past the waterfall on a very difficult stretch, 40 minutes, to the Vinte e Um canyon, where base camp sits facing walls of around 80 metres. The guide sets up camp and prepares dinner.
Day 2
Up the canyon + Fumaça from above + Vale do Capão
10 kmHigh
Out at 8:00 am, after breakfast, upstream. We pass difficult but visually striking stretches, walking alongside the canyon walls. It is 2 to 3 hours to Fumaça Waterfall seen from above and another 1.5 hours to Vale do Capão, where the car is waiting to take the group back to Lençóis.

up to 24 km in totalHigh
If the group chooses the 3-day format, day 2 does not go up to Fumaça from above: it continues for an hour to the lookout facing Fumaça Waterfall head-on and another hour to the Palmital Waterfall camp, where you spend a second night. The exit falls to the following day — confirm the exact route with us when you settle on a date.

Footwear and rain gear matter most here: almost the whole route is in the riverbed, between canyon walls. If you would rather not carry the weight, a personal porter can be arranged. Items are checked at booking and at check-in.

The mammoth protects the herd. Always.

Local trekking guides, trained in pre-hospital first aid (APH) and in minimum guiding competencies (CMC, to Brazilian ABNT standards), some with WAFA certification — ask us about availability. All carry a remote-area first-aid kit. The protocols start before the tour, in the intake form every participant fills in.

Risks and limitations — please read

This is the most demanding route in our catalogue, and the operator itself recommends it for very experienced hikers only. Day 1 is rated extreme effort — the only one so rated across all our routes: 3.5 hours in the riverbed and then 40 minutes climbing past the waterfall on a very difficult stretch. The route is little-walked and isolated, which means any rescue takes longer than the already long regional norm. If you are unsure about your fitness, talk to us before booking — this is not the route on which to find out.

In operation we carry portable radios and the two-way SPOT X satellite communicator, with an S.O.S. button for extreme situations.

This is not a 100% safe activity. Even with every precaution, mishaps and accidents can happen — as in virtually any adventure activity in a natural environment: venomous animals, falls causing fractures and grazes, storms, flooding. Mechanical failures in the transport can also delay or alter the itinerary.

The activity takes place in wilderness, where rescue can be slow: help may take more than 5 hours to arrive, and the cost of the rescue falls to the participant — it is not included in the booking.

During the activity, follow the team’s instructions strictly. Carrying every mandatory item on the checklist is essential: missing any one of them makes participation impossible.

A 50% deposit confirms the booking, by transfer, deposit or boleto. The remaining 50% at check-in in cash, or by deposit up to 2 business days before.

Card payments carry a 6% surcharge and can be split into up to 12 instalments, according to the rates charged by PagSeguro, Mercado Pago and similar providers.

Send the receipt with the confirmed date, and the full name and ID number of each participant.

Cancellation by the traveller follows Brazilian EMBRATUR normative resolution no. 161/1985:

30+ days before: 90% refunded
21–29 days: 80% refunded
7–20 days: 50% refunded
Fewer than 7 days: no refund
During the package: no refund

Before cancelling: you can name a replacement or keep the amount as credit for another date. Booking fee: 10% as a penalty if you cancel after confirmation.

No-show: failing to appear means losing the full amount. Mamut may change the itinerary when the weather compromises safety; the tour runs even in rain, except in cases of force majeure.

We work with a network of partners. If a tour is passed on to another operator, the prices charged may vary with the number of participants, the type of tour and the logistics required — they may match our counter price, or be adjusted up or down.

By booking with us, you agree that where a tour is passed on, delivery of the service becomes the responsibility of the designated operator. Our role is to broker the booking and ensure that what was contracted is delivered; we are not liable for price differences identified after booking.
