Pedra Furada: Jalapão's Sandstone Window at Sunset

Pedra Furada is a natural sandstone arch about 35 km from Ponte Alta do Tocantins, at the end of a dirt road that demands a 4x4. The formation opens a roughly 15-meter-high window onto the Cerrado, and most visitors time their stop for the final hour of daylight, when the low sun turns the rock face a deep amber. Entry costs around R$35 per person (fees are subject to change — check with your tour operator for current rates), and you get about 20 minutes at the main viewpoint before the next group is waved through.

Getting There and Understanding the Site

The attraction sits on private land within the Jalapão region, and the access road is sandy enough that a standard hatchback will struggle after rain. Most travelers arrive as part of a guided 4x4 expedition from Palmas, which is roughly 300 km away, or from Ponte Alta do Tocantins, the usual gateway town.

Location and Access from Ponte Alta

From Ponte Alta, the drive takes 40 to 50 minutes along the TO-130, a dirt track that passes through open Cerrado and a few scattered farms. There is no public transport. If you are self-driving, air down your tires slightly before the final sandy stretch — locals do this to avoid digging in, and it makes the last few kilometers noticeably easier.

The parking area sits at the foot of the rock formation, with a small information center and restrooms. From there, a short trail of about 0.79 km leads to the base of the arch. The walk takes 5 to 10 minutes and is rated easy, though the final approach involves a set of wooden stairs.

The Geology and Why It Looks Like This

The arch is carved from sandstone roughly 60 million years old, laid down when the region was a much wetter environment. Wind and seasonal rain have worn away the softer layers, leaving a natural bridge with a clean, almost circular opening. The rock is fragile — signs ask visitors not to scratch or write on the surface, and the restriction is enforced because the sandstone erodes quickly once its outer crust is broken.

What to Expect During Your Visit

This is a short stop, not a half-day excursion. The site operates from 7:00 to 17:30, and the 20-minute limit at the main viewpoint is strictly applied by staff. Groups are called up in sequence, so you may wait 10 to 15 minutes at the base before your turn.

The Viewpoint and the Sunset

The arch frames the flat Cerrado plains to the west, and at sunset the light comes straight through the opening. It is the reason most itineraries schedule Pedra Furada as the last stop of the day. Arrive by 16:30 if you want to shoot without a crowd of phones in the frame — by 17:00 on a July weekend, the viewing platform can hold 40 or more people at once.

Helmets are handed out free at the entrance and must be worn on the stairs. The reason is practical: bees nest in the crevices of the rock, and a knock against the stone can disturb them. Staff will tell you to move slowly and keep noise down. If you are allergic to bee stings, carry your medication and consider viewing from the lower platform instead of the upper stairs.

Facilities and Practical Rules

The site has restrooms, a small snack kiosk, and shaded seating near the parking area. Food and drinks are not allowed inside the rock area itself. Groups are asked to keep quiet — both for the bees and for other visitors. There is no ATM and no card machine at the entrance, so bring cash or check that your guide has arranged payment in advance.

When to Go and How to Combine It with Other Stops

The dry season, from May to September, gives you the most reliable road conditions and the clearest sunset light. July is the busiest month, with school holidays pushing daily visitor numbers up sharply. If you can travel in April or May, you get dry roads and roughly half the crowd — several guides I spoke with in Ponte Alta said April is their personal pick.

The rainy season, November to March, brings green scenery but slippery access roads and a higher chance of a closed gate at the entrance. The formation itself is still visible in the rain, but the sunset window is often blocked by cloud.

Pairing Pedra Furada with Nearby Attractions

Pedra Furada works best as a late-afternoon stop on a day that starts at one of the region's water attractions. A common route runs from Lagoa do Japonês or the Sussuapara Canyon in the morning, lunch in Ponte Alta, and Pedra Furada at 16:00. The Cachoeira da Velha is another option, though it is further north and makes for a long driving day if combined with the arch.

Frequently Asked Questions

How long do you actually spend at Pedra Furada?

Plan for 45 minutes to an hour on site, including the walk from the parking area, the wait for your group's turn, and the 20 minutes at the viewpoint. The visit is deliberately short — it is a photo stop, not a hiking destination.

Do you need a guide to visit Pedra Furada?

No guide is required for the site itself, but the access road is unsigned and sandy, and most rental cars in Palmas are not 4x4. Independent travelers with a high-clearance vehicle can drive in, pay the entry fee at the gate, and walk up without a guide.

Is Pedra Furada suitable for children or older visitors?

The lower viewing platform is reachable via a short, flat path and is manageable for most mobility levels, including visitors who use a cane. The upper stairs are steep and narrow, and the bee activity makes them less suitable for young children or anyone with a sting allergy.

What should you bring to Pedra Furada?

Bring cash for the entry fee, a hat, and water for the walk up. Avoid strong perfume, scented sunscreen, or insect repellent with a heavy fragrance — these can attract the bees that nest in the rock. Closed shoes are better than sandals on the sandy trail and stairs.
