River Deep, Mountain High
It’s six long hours from Salvador to Chapada Diamantina, the Diamond Highlands of Brazil, and roadkill breaks the monotony of the featureless Brazilian sertão (hinterland). Occasionally, we encounter the odd farmhouse with concrete walls and a corrugated roof. Dogs bark while chickens cackle loudly and avoid our bus just in time. They must have clocked what happened to their less-nimble brethren.
I’m heading to Lençóis, the gateway to the Chapada Diamantina National Park, whose remoteness and lack of infrastructure are its biggest assets. Backpackers are slowly discovering this forgotten corner of the world and the adventure operators who have sprung up can’t find enough tour leaders to cope.
When I arrive, I immediately seek out Esmeraldo, a veteran with shoulder-long white hair and one of the most experienced Chapada guides. He shares with me a few beers on my first night out in Lençóis.
“Three days?” he says and shakes his head when he hears how long I plan to stay. “It takes three days to hike to the valley of Capão! You can go trekking, canyoning, climbing, biking, caving, swimming – but you have to stay for a week or so.”
He teams me up with Nils, a sensible, sociable Swede who is snacking on cassava chips a few tables back. He’s here for three days, too.
The next day Nils and I are up early for a jeep ride with Esmeraldo to pick up the trail to Lapa Doce, the third largest cave in Brazil. Not only does the landscape change after every turn, but so, it seems, does the ecosystem. We leave the shadow of the last vestiges of the thick Atlantic rainforest and enter the distinctive woodland savanna of the Cerrado. Here canopy cover is patchy and the sun hits us like a rock.
Esmeraldo points at trees we haven’t heard of before: this one here with the large trunk is a mulungu, whose bark has been used for centuries as a sedative. That one is an aroeira – its resin smells of soap and the essential oil is used in cosmetics. As for the one over yonder whose leaves form a tuft at the top – that’s an amburana honey tree, whose seeds are crushed to give tobacco a sweet perfume.
“As for this one,” Esmeraldo says touching a strong, sturdy tree, “this one is a braúna. The best hardwood you’ll find. Used in construction everywhere in Brazil, ’cos it’s termite-resistant.”
When we finally reach the cave entrance, Esmeraldo dons a dust mask. Why? Because, unlike most caves, Lapa Doce is not wet, slippery and cool, but dry, sandy and warm. Its floor is covered with fine silica particles that float when disturbed.
Nils is, not unreasonably, worried.
“You’re both OK,” says Esmeraldo. “It’s us guides who come here frequently who need protection. The dust can cause lung problems.”
But he still gives us a form to sign our rights away.
Despite being dry, the cave has stalactites, formed during the wet season that lasts for six months. They are thin and slightly crooked because of a faint yet permanent breeze we can only just perceive on our skin. The dimensions are staggering: you could fit a cruise boat in the first chamber and still have space to turn it around. The soft floor muffles our steps and magnifies the pervading stillness. Deep in the cave’s innards, rusty irrigation water from the farmland above has caused its most memorable sight: a curtain of stalactites white on one side and dark red on the other, like a bleeding wound.
East of Lapa Doce, a new ecosystem merges with the Cerrado: the Caatinga, which brings to mind the chaparral of the American West. The vegetation is arid lowland scrub, while the soil is poor and acidic, giving rise to oases whose waters are as transparent as cellophane. Seven or so kilometres later, we reach Pratinha (Little Silver). It’s not really a lake but the mouth of a submerged river flowing out of a cavern decorated by xique-xique cacti, shaded by lianas and framed by water lilies. The river continues inside the cavern where you can snorkel underground, following a guide boat through a narrow channel. It costs extra, but it would, wouldn’t it?
Nils opts for snorkelling, while I lie in the sun outdoors and refresh myself in the lake. When he emerges, his skin full of goosebumps the size of my nipples, I know I made the correct decision.

“The water is icy cold and dark – you can’t see a thing,” he says with a disappointed expression. “But I’ve learned something interesting.” He dives in the lake and emerges with a handful of sediment. “Look closer,” he tells me.
I rub my fingers in the sand. It’s white and brittle.
“It’s dead mollusc shells,” he explains. “They live so far inside that no one has ever found a live one yet. They’re washed out of the depths of the cave when they die.”
The next day’s hike is at the northern tip of the park. Around us are large craggy domes. We are aiming for the peak of Pai Inácio, the picture-postcard of the Chapada.
It’s a short and strenuous near-vertical climb to the top, but the eagle’s-eye view from the summit is worth it. The Sincorá range that forms the backbone of the park ends in solitary wind-eroded outcrops, each one an island with its own ecosystem. Indeed, nature has built a veritable Japanese rock garden at our feet. Each boulder is mottled with multi-coloured lichen, while bromeliads have taken shelter in every crack and depression. Plants here have waxy leaves to reduce evaporation and hardy roots that make the best out of the thinnest topsoil imaginable.
The careful hike down takes longer than the trek up. Sweaty and thirsty, we order juice at a mobile canteen. The trees of the Cerrado are thin and frequently stunted, their leaves slight and plentiful, and their fruit undersized and tart. There are the old supermarket faithfuls: mango, banana, coconut and papaya. But umbú? The size of a kiwi and with the skin of a smooth lime, this fruit has greenish-yellow juice that tastes like a sweeter version of grapefruit. I imagine it mixed with gin and order a second one.
We pick up the trail by Rio Mucugezinho, a river that crosses the park, with water the colour of tea. There is no trail other than the riverbank, necessitating climbing over large boulders, jumping across rocky slabs and negotiating tricky bogs under a gallery forest. We are followed by the screeches of a marmoset family we hear more than see. Every upwards glance is a sign for them to scamper quickly to the canopy. When we reach a bathing spot with a sizeable crowd of swimmers they disappear. But no, it’s not because they’re afraid of people. As Esmeraldo explains, this lucrative location is the home of a rival marmoset clan. These guys are much less circumspect, hanging from the branches of the trees trying to spot discarded biscuits.
Another 20 minutes and we reach Poço do Diabo (Devil’s Pool) where the Rio Mucugezinho forms a small cascade – if 20 metres is small for you. Nils and I jump in feet first, swim to the falls and let the current thump our shoulders for an environmentally friendly hydromassage. The water is cold and works wonders on our aching muscles. We are tired with satisfaction fatigue, for our bodies are responding to exertion with a heavy dose of adrenaline.
That night, exhausted, I drink Nils under the table. Months later, I find out that I made him miss his early bus to Salvador.
I spend my last day in Lençóis walking around the town, taking in its imposing, diamond-baron palaces, many of them now neglected and decomposing under the tropical sun. I end up making the short trek to the Serrano waterholes – shallow rock pools where the constant swirling movement of the Lençóis River turns them into natural jacuzzis. I am the only gringo there, but have visions of a future spa right by that copse of trees on my left. It’s going to call itself an ecolodge because it will be built from local, termite-resistant braúna tree. But make sure you beat the spa there.
LATAM Airlines flies to Salvador from Sydney via Santiago and São Paulo.
Azul has flights between Salvador and Lençóis three times a week.
Alternatively, Real Expresso runs four buses a day to Lençóis. realexpresso.com.br
There is a wide range of accommodation at Lençóis, although the hostels are rather basic. The Swiss-owned and managed Vila Serrano lies on a small hill overlooking Lençóis and offers quiet, superbly furnished doubles from about US$70.
A cheaper alternative closer to the centre is Pousada Raio do Sol, with doubles from about US$50.
The number of adventure companies in Chapada Diamantina is increasing by the year, but Esmeraldo’s agency, Vertical Trip Adventures, is one of the oldest and most reliable in town.
For hardened hikers, Extreme EcoAdventure offers some exclusive treks, including the Big Six waterfalls hike, to the more remote areas of the park. extremeecoadventure.com.br
