Dunas do Jalapão: Golden Sand Dunes in Tocantins

The Dunas do Jalapão are a 40-meter-high field of orange sand on the edge of Mateiros, roughly 300 km east of Palmas in Tocantins state. Entry is free, but you cannot walk in alone: every visitor must be accompanied by a Naturatins-credentialed guide and present a voucher booked online in advance. The dunes are the only dune field inside Brazil's Cerrado savanna, and the sand under your feet was once the sandstone of the Serra do Espírito Santo — wind carried it grain by grain over millennia and dropped it here.

Sunset is why people come. Arrive around 16:00 in the dry months and the light turns the sand from pale gold to burnt orange within about 30 minutes. The climb is short but soft — a marked side trail of roughly 20 minutes from the parking lot leads up the ridge, and direct climbing up the frontal dune wall is forbidden to keep the face from collapsing.

Getting There and Orienting Yourself

From Palmas to the Dune Field

Palmas is the gateway. Brigadeiro Lysias Rodrigues Airport (PMW) receives daily flights from São Paulo, Brasília and Belo Horizonte, and from the capital you are looking at a minimum of four hours of driving to reach Mateiros or São Félix do Tocantins, the two towns most travelers use as a base. The final stretch into the dunes is unpaved and heavily rutted — locals call the ridges of hard-packed earth "costelas de vaca" (cow ribs). The 37 km from Mateiros took more than an hour in a 4x4; a standard sedan will not survive it comfortably.

Most visitors join a guided 4x4 expedition rather than self-driving. Package prices run about R$350 to R$700 per person for a multi-day itinerary, and operators must be registered with Cadastur, Brazil's federal tourism registry. If you hire a driver-guide independently, confirm the guide's Naturatins credential before you leave town — the checkpoint at the dunes gate does not accept unaccompanied vehicles.

Where the Dunes Sit in a Jalapão Itinerary

A sensible placement is day three or four of a five-day loop: Serra do Espírito Santo at sunrise, a fervedouro (the natural spring pools where water pressure keeps you afloat) in the early afternoon, then the dunes for sunset. From Mateiros the drive is short enough that you can also slot the dunes in after a morning at the Cachoeira da Velha. Do not squeeze them into a transfer day. The road is slow, the gate closes for entry at 17:30, and a rushed arrival means you climb in failing light.

A detour worth taking: the quilombola community of Mumbuca, on the road toward Mateiros, where artisans weave capim dourado — the golden grass harvested in the surrounding Cerrado — into bracelets and baskets. It is a 30-minute stop that puts the sand you are about to see in context, since the same dry-season landscape produces the grass.

Hours, Vouchers and the Rules That Actually Matter

Booking and Capacity

Entry is free. The voucher is not. You reserve a slot through the Tocantins ecological tourism portal, and the documented daily cap is 600 visitors, with the site operating under Instrução Normativa nº 02/2024. Visitors over 60 are exempt from the fee but still need a voucher. Groups are capped at 60 people per entry period, so a guide who tells you to "just show up" is either misinformed or planning to leave you at the gate.

Access windows run 06:00 to 10:00 in the morning (stay until 11:00) and 14:00 to 17:30 in the afternoon (stay until 18:30). Some published sources list a simpler 08:00–18:00 window, and hours have shifted between seasons — fees and timetables are subject to change, so check the official Naturatins or state tourism site for current rates and slots before you book transport.

Prohibitions Worth Knowing Before You Pack

No fires, no alcohol, no cigarettes, no food, no portable speakers, and no pets except guide dogs — in the dunes and in the parking lot. Leave the picnic and the Bluetooth speaker in the car. Drone flights are banned. Collecting sand, plants, rocks or any other material is an offense, and yes, people try to bottle the orange sand; rangers check.

Wedding and quinceañera photo shoots are still permitted, but only with prior notice and authorization from Naturatins. If you are traveling for a personal shoot, arrange that weeks ahead, not at the gate.

Best Time to Go and What the Sand Does

Dry Season Versus the Wet

The dry season runs May through September, and that is the window to aim for. Tracks are passable, skies are clear, and the dune colors are at their most saturated. September in particular brings firm drought, high transparency in the fervedouros and dependable orange sunsets. From October to April, rain turns the access roads into mud pits and can strand a 4x4; the landscape greens up and crowds thin, but the risk of losing a day to a stuck vehicle is real.

Temperatures during the day climb high enough that the sand absorbs heat fast — wear shoes for the walk up and switch to bare feet at the top. Carry more water than feels necessary; there is no shade on the ridge.

Two Good Times of Day, Two Different Photos

Late afternoon between 16:00 and 17:30 is the classic slot, and the crowd knows it. If you want the dunes closer to empty, take the morning window instead: entry from 06:00 puts you on the ridge for sunrise with temperatures 10°C or more cooler than midday and a fraction of the visitors. The trade-off is that morning light is flatter. Sunset is the postcard; sunrise is the quieter, better-value experience, and most itineraries skip it entirely.

Frequently Asked Questions

How much does it cost to visit the Dunas do Jalapão?

Admission is free of charge, but you must obtain a voucher through the state's online booking system and enter with a licensed guide — travelers over 60 pay nothing yet still need the voucher. Expect the transport and guide to be the real expense, typically folded into a R$350–R$700 per-person 4x4 package. Fees and booking rules are subject to change, so confirm on the official Naturatins portal.

Can I drive to the dunes in a regular rental car?

No. The last 37 km from Mateiros are unpaved with severe rutting, and the documented travel time exceeds an hour in a high-clearance 4x4. A standard rental car risks damage and, more practically, will not pass the conditions locals describe as cow ribs. Join a Cadastur-registered operator or hire a 4x4 with driver.

How long do you need at the dunes?

Plan about two hours on site: a 20-minute walk up the marked side trail, 45 to 60 minutes on the ridge, and the descent. Add the drive from Mateiros, which is short in distance but slow in time. Arriving by 16:00 gives you a comfortable buffer before the 17:30 entry cutoff.

Is the sunset really worth the effort?

The color shift is the main event — the sand goes from pale to deep orange as the sun drops, and the lake below the ridge reflects the Serra do Espírito Santo. It is the region's signature image for good reason. That said, the morning entry window delivers the same dunes with far fewer people, and for photographers who dislike crowds, it is the better call.
