Serra da Diamantina Highland Circuit
Diamond rush ghost towns in Brazil's highlands
The Serra da Diamantina rises from Bahia’s interior like a lost world, where 18th-century diamond rush towns cling to mountainsides and ancient quartzite formations create otherworldly landscapes. This circuit connects Lençóis, Mucugê, and Andaraí through backcountry tracks that thread between table mountains and plunge into hidden valleys where waterfalls drop hundreds of meters into crystal pools. The route passes abandoned mining settlements like Igatu, where stone ruins tell stories of Brazil’s mineral wealth boom and bust.
Moderate to difficult depending on route choices—some sections require high-clearance 4WD and winch-capable recovery gear during rainy season. Dry season (April-September) offers the best conditions, though flash floods can turn creek crossings deadly year-round. No permits for main tracks, but national park sections require entrance fees. Fuel up in Lençóis or Mucugê before heading into the highlands. This is technical driving through some of Brazil’s most dramatic scenery, where every turn reveals another geological marvel and the night sky explodes with stars unmarred by light pollution.

Frequently asked questions
Will a stock lifted 4x4 handle the Serra da Diamantina circuit, or do I need lockers?
A bone-stock 4WD with decent ground clearance can complete most of this trail, but the rocky highland sections will punish low-clearance rigs and test your skid plates hard. Lockers aren't required but will save you on the looser boulder fields. All-terrain tires are non-negotiable on 300km of quartzite rock.
Can I run this trail in October or November?
Don't. October through March is the wet season in the Chapada Diamantina and the water crossings go from manageable to vehicle-swallowing fast. April through September is dry season — that's your window, with July and August being peak conditions.
Do I need permits to drive the highland circuit, and where do I get them?
Yes — portions of the route pass through Chapada Diamantina National Park, managed by ICMBio, and access requires registration. Get permits at the ICMBio office in Lençóis before you roll out; rangers do check, especially near Pai Inácio and the core park zones.
What's the hardest section of this trail and what actually makes it difficult?
The high plateau tracks between the table mountains (chapadas) are the crux — exposed quartzite slabs, embedded rock ledges, and loose stone descents with no bailout and zero cell service. The challenge isn't one single obstacle but 30–50km of sustained technical terrain that punishes inattention and rewards careful tire placement.
Is there any fuel or resupply between Lençóis and the far end of the circuit?
Fuel is only reliable in Lençóis at the start — the ghost towns and small communities along the route have nothing consistent. Carry enough fuel for 350–400km to be safe, plus water for multi-day stretches since stream crossings exist but water quality is variable and purification gear is essential.
