Estrada Real by Car: Caminho Velho Itinerary and Days Needed

The Estrada Real is Brazil's longest tourist route, covering about 1,630 km across Minas Gerais, Rio de Janeiro and São Paulo. Since 2023 it has been a national monument by law, and the annex to that law lists 182 municipalities and districts.

What almost nobody explains is the detail that shapes the trip for anyone going by car: the official route was designed for people on foot, on bikes or on horseback. On the Caminho Velho (the "Old Road"), the best known of the four, 82.5% of the marked route is dirt road and another 6% is trail. You can't drive that line. What you drive is the sequence of towns, and you take the dirt wherever you want.

In short: The Caminho Velho of the Estrada Real links Ouro Preto to Paraty, with 710 km on the official route. By car the trip comes to around 600 km and about 13 hours of actual driving, which works out to 4 to 5 days at a tight pace and 7 to 8 days at an easy one. The Estrada Real passport is free and you pick it up by handing in 1 kg of non-perishable food. The best season for the dirt sections is the dry season, from April to September.

Four roads, and why the Old Road is the one that matters

The Estrada Real has four branches, all with data published by the Instituto Estrada Real: the Caminho Velho (710 km, Ouro Preto to Paraty), the Caminho Novo (515 km, Ouro Preto to Porto Estrela, in Magé), the Caminho dos Diamantes (395 km, Diamantina to Ouro Preto) and the Caminho do Sabarabuçu (160 km).

The Caminho Velho was the first road officially opened by the Portuguese Crown to connect the mining region to the coast of Rio de Janeiro. In the 17th century the journey on horseback took 60 days. It is the longest branch, the one with the most historic towns and the one best set up for visitors.

One correction worth making right away, because half the itineraries online get it wrong: Mariana is not on the Caminho Velho, it's on the Caminho dos Diamantes. It sits 13 km from Ouro Preto and is worth a day trip, but it isn't on the Caminho Velho route.

What changes when you go by car

The official 710 km route breaks down like this: 586.5 km of dirt road, 75.5 km of asphalt, 38 km of trail and 10 km of old stone paving.

Cars can't get through the 38 km of trail, and that's not a problem: the Instituto's own official GPS file includes tracks marked as "car section" that bypass each of them. Added up, that's about 46 km of road detours. The biggest one comes right at the start, between Ouro Preto and São Bartolomeu, where the 18 km trail is rated by the Instituto as highly difficult and the car detour covers it in 12 km.

In practice, measuring the road route between the official landmarks, Ouro Preto to Paraty comes to about 600 km and 13 hours behind the wheel. The car makes it shorter, not longer.

The 10 km of old paving lie between Tiradentes and São João del-Rei, and it's the most photographed stretch of the whole route. Take it slowly, with a light load in the car, and no rush.

The towns, in the order they appear

Heading down from Ouro Preto to Paraty: Ouro Preto, Congonhas, Entre Rios de Minas, Lagoa Dourada, Prados, Tiradentes, São João del-Rei, Carrancas, Cruzília, Caxambu, São Lourenço, Itamonte, Passa Quatro, Guaratinguetá, Cunha and Paraty.

The Caminho Velho has a symmetry few routes in Brazil can match: it starts and ends at a UNESCO World Heritage Site. Ouro Preto joined the list in 1980 and was the first Brazilian cultural site to be recognized. Paraty joined in 2019, as a mixed cultural and natural site. And halfway there's a third one, Congonhas, inscribed in 1985 for Aleijadinho's twelve soapstone prophets.

Baependi and São Thomé das Letras are also part of the Caminho Velho, but they sit off the main spine. Baependi fits in easily, just 6 km from Caxambu. São Thomé is a big detour, 45 km from Baependi, and it's only worth it if you have a day to spare.

The two stretches that call for care

Carrancas to Cruzília is the slowest part of the route. It's 56 km that take close to an hour and forty minutes, an average of 33 km/h, on roads literally named Estrada Real. It's also the stretch where the Instituto records the steepest climbs and the least shade. Filling up in São João del-Rei before heading in is the obvious precaution, because the gaps between towns in this part run over 60 km.

Cunha to Paraty is the mountain range, and it's the stretch that demands the most from the driver. It's 46 km in almost an hour and forty minutes, an average of 27 km/h, descending the Serra do Mar inside the Serra da Bocaina National Park. The road is paved, but it's in poor condition and that's on record: in March 2026 the Paraty City Council officially reported precarious stretches on the RJ-165, an unfinished bridge project and single-lane traffic inside the park. Before that there were already reports of potholes, illegible signage and landslides after heavy rain.

The practical takeaway is simple: spend the night in Cunha and drive down the mountain in daylight. Faded signs, single-lane traffic and tight curves in the dark is a combination that isn't worth it.

Since much of the route is rural dirt road, it's worth going through the vehicle maintenance checklist before you leave, especially tires, spare and suspension.

The passport, which almost nobody explains properly

The Estrada Real passport is a record that you passed through each town. It comes in two versions, and the Instituto itself warns that they don't sync with each other.

The virtual version works in the official app, with geolocation check-ins at set points, and the certificate is issued automatically when you complete a road.

The physical version is the one with the curious detail: it's free, but it costs 1 kg of non-perishable food. You register, get a code by email, and show that code at a pickup point along with the food, which is donated to a local charity.

For anyone driving the Caminho Velho, the useful pickup points are in three towns: Ouro Preto, São João del-Rei and Paraty. After that, you collect stamps at more than 80 accredited points along the roads, one per town. To earn the Caminho Velho certificate you need 14 stamps.

How many days it takes

The Instituto doesn't publish a day estimate for driving the Caminho Velho. Working it out from driving time, with 3 hours behind the wheel per day and the rest of the day free for the towns, it adds up like this:

• 4 to 5 days: doable, but you'll pass through Ouro Preto and Tiradentes without really seeing them.
• 7 to 8 days: a full day in Ouro Preto with day trips to Mariana and Congonhas, a day in Tiradentes and São João del-Rei, one in the Circuito das Águas (the spa towns circuit), one in Paraty, and you still have slack for rain or the unexpected.

This is the kind of route worth planning ahead in GT Overlander: you describe the trip in plain language and the AI builds the route with the stops and the context of each town, already split to fit your days.

When to go

In Minas the rainy season runs from October to March and the dry season from April to September, according to the official definition of the state water management agency. Since most of the route is dirt, the good window is April to September.

Coming from Belo Horizonte, start in Ouro Preto: it's 97 km away, and you drive down the whole route with the elevation in your favor. Coming from São Paulo or Rio, start in Paraty, which is a little over 250 km from both cities. If you arrive via Paraty you'll go through the Rio-Santos toll, which has no gates and charges around R$ 5 on weekdays and R$ 8 on weekends, prices as of September 2026.

If you feel like stretching out along the coast before heading up the mountains, the Costa Verde between Angra dos Reis and Paraty connects directly. And if you have time left in Minas, the Serra da Canastra is in the same state, with a different kind of road.

Frequently asked questions

Can you do the Estrada Real in a regular car?

The sequence of towns, yes, and that's what most people do. The official marked route, no: it's 82.5% dirt and 6% trail, and it was designed for hikers, cyclists and riders. It's worth noting that there is no official document from the Instituto or the highway authority requiring 4x4 or a minimum ground clearance on any stretch, so the decision is up to you and the condition of your car.

How many km is the Estrada Real?

About 1,630 km across the four roads, a figure that appears both at the Instituto Estrada Real and in the law that made it a national monument. The Caminho Velho alone is 710 km on the official route, and about 600 km by road.

What's the difference between the Caminho Velho and the Caminho Novo?

The Caminho Velho is the original, opened in the late 17th century connecting Ouro Preto to Paraty on the coast. The Caminho Novo was opened between 1722 and 1725 as a shorter alternative to Rio, passing through Barbacena, Juiz de Fora and Petrópolis. The Caminho Velho is where the historic towns are concentrated; much of the Caminho Novo became a modern highway corridor.

Does the passport cost anything?

No. It's free. The physical version asks for 1 kg of non-perishable food at pickup, which goes to donation.

How many days do I need?

4 to 5 days to see the essentials, 7 to 8 to do it at an easy pace. If it's your first time, go with the longer option: the towns deserve time and the Cunha mountain road shouldn't be rushed.

The oldest route in the country

The Estrada Real isn't a road, it's a system of trails that Brazil used for three hundred years and then nearly forgot. What's left is the best sequence of historic towns in the country, linked by dirt roads that still run where mule trains once passed.

Take it slow. It's a short route in kilometers and a long one in everything else.
