Imagine wandering through a sun-scorched expanse that masquerades as a desert, only to discover it's teeming with life—vibrant turquoise lagoons, hidden paths known only to locals, and a rhythm of nature that challenges every step you take. But here's where it gets controversial: as this Brazilian gem explodes in popularity, is the rush of tourists eroding its very soul? Dive in with me as we explore Lençóis Maranhenses, a place where the sand shifts beneath your feet and time seems to stand still—yet change is the only constant.
Lençóis Maranhenses isn't your typical arid wasteland; it's a mesmerizing blend of desert-like dunes interspersed with shimmering pools, quaint villages tucked away, and ancient trails decipherable only by seasoned guides. For beginners unfamiliar with such landscapes, think of it as a giant sandbox where wind-sculpted hills rise high, but rainwater collects in depressions, creating natural basins that hold freshwater—turning the whole scene into a watery wonderland during the rainy months.
I found myself trailing my group by about 20 paces, and our guide another 30 ahead, when he abruptly halted, glanced at his wristwatch, and gazed upward, seemingly guided by the sun's position. 'We're off course,' I assumed to myself. The surroundings were a sea of gentle, pale mounds undulating endlessly, dotted with sparkling blue-green pools that blended seamlessly into the horizon—no clear start or finish in sight. Reassured by some unseen signal, our guide pressed onward, navigating an invisible path that only he could perceive.
My companions and I were midway through a three-day expedition across Lençóis Maranhenses National Park (accessible via https://parquelencoismaranhenses.com/en/), an awe-inspiring 1,500 square kilometers (about 579 square miles) of sand in northeastern Brazil, and my internal compass had completely failed me. I trudged in quiet contemplation, tuning into the whispers of the breeze, the gentle lapping of water, and the crunch of grains underfoot.
Every footfall sank me a couple of centimeters into the loose powder, doubling the effort required to move forward. I kept lagging, swapping from flip-flops to water-resistant shoes, and eventually ditching footwear altogether as the surface hardened under the relentless sun. A buddy who'd tackled a similar journey back home had cautioned me: 'You'll discover muscles in your feet you didn't know existed.' By then, I was convinced they were right—and this was just the start.
This isn't a static terrain; it's a breathing, evolving ecosystem. Hemmed in by verdant forests on one flank and the crashing Atlantic waves on the other, Lençóis Maranhenses stands out as one of Brazil's most extraordinary natural setups. Fierce coastal gusts carry sand inland, forging a dune-dominated vista where peaks can soar up to 30 meters (roughly 98 feet). And this is the part most people miss: it's not truly a desert. From January through June, torrential rains fill basins between the dunes. A dense, impermeable layer of sediment traps the water, birthing hundreds of crystal-clear freshwater lagoons that beckon swimmers, waders, and those seeking a buoyant escape.
Our adventure kicked off right after dawn on the first day. Our leader, Carlos Otávio Rêgo (find him at https://www.instagram.com/tavzareia/), affectionately called Tav by all, maintained a brisk tempo from the outset. We swiftly approached our inaugural descent, where I clumsily surfed down on my feet like improvised skis, desperately avoiding a tumble.
From the base, the dunes morphed into colossal barriers and shaded arcs that seemed insurmountable. We skirted enormous lagoons resembling rivers and forded several, occasionally hoisting our gear overhead through waist-high waters. But here's where it gets controversial: the surge in visitors is straining the park's delicate balance. Increased footfall leads to infrastructure overload, unauthorized vehicle incursions, and a boom in high-end property development encroaching on its borders. Safeguarding Lençóis—and its resident communities—rests on the shoulders of dedicated figures like park manager Figueiredo.
'Several thousand families call Lençóis Maranhenses home,' she shared with me. Her team has recently conducted a comprehensive survey and mapping of these settlements to pinpoint their needs and gauge sustainable visitor capacity. She's been engaging directly with villagers, empowering them to shape their involvement through community-run accommodations and pit stops amid the sands.
'To truly connect with this exceptional habitat, there's no substitute for trekking on foot,' Figueiredo emphasized. 'It lets you spot the finer details: the ever-moving grains, animal tracks, and the subtle marks of wildlife.'
For me, opting to traverse Lençóis barefoot transcended mere physical exertion; it was an invitation to embrace the park's more serene, undiscovered facets—including pristine lagoons untouched by the masses.
Our journey launched from Lagoa Bonita, a lofty dune area close to Barreirinhas on the park's western edge. Ahead lay 36 kilometers (around 22 miles) of sandy terrain, punctuated by two nights in local hamlets, culminating in Atins—a coastal hub buzzing with day excursionists.
Planning your own escapade? Timing is key: Aim for June to September when lagoons brim with water (July and August are busiest). Base yourself in Barreirinhas, Santo Amaro do Maranhão, or Atins for easy access. Arrange outings or treks via a local ecotourism outfit like Costa Leste Ecoaventura (check https://www.costalesteecoaventura.com/) or a vetted guide such as Tav (@avzareia at https://www.instagram.com/tavzareia/). They'll handle itineraries, provisions, village lodgings, and gear transport. Typical treks span 3-5 days, so budget a full week for travel and downtime. Reach the area by flying into São Luís (SLZ), then driving and boating 4 hours to Barreirinhas, or 5-6 hours to Santo Amaro or Atins.
Our initial day's highlight was spotting the tiny enclave of Mucambo, a splash of greenery amidst the dunes—trees at last! Our digs were basic yet charming: vibrant hammocks under palm-thatched roofs, chilly showers, and minimal power for devices. My gaze locked onto the communal feast: steaming bowls of rice, beans, and freshly grilled fish. After pounding 15 kilometers (about 9 miles) through sand, it was pure bliss.
Strolling through the tranquil village that afternoon, we chatted with a porch-sitting family. A little girl cradled a baby goat, eagerly passing it to us. 'She won't nip!' her mom assured. Handing my pal a bottle for feeding, we chuckled as the critter bleated for more. Such personal moments would vanish in a throng of hikers, underscoring the intimacy of smaller groups.
Tav noted a sharp uptick in crowds compared to the previous year, especially from June to September: 'One oasis guesthouse hosted 120 guests at once.' In peak times, he'd wrap one trek and dive into another immediately.
Raised on the park's periphery, Tav reminisced about boyhood camping under starry skies and coastal fishing, mimicking fishermen's routes. Early on, he'd fixate on a lone dune for orientation. 'It flows instinctively now,' he explained. 'Eyes shut, I visualize every mound and path—enabling nocturnal hikes in total black.'
We encountered numerous drained lagoons, remnants of the dry spell, sparking brief disappointment. Yet Tav always located hidden blue depths for a proper dip. A standout was a massive dune requiring minutes to ascend, followed by an exhilarating, out-of-control dash to the water. Tav etched 'Sou das areias'—'I am from the sands'—with ease, radiating hometown pride. 'This is my sanctuary, my workspace, my identity,' he said. That deep-rooted connection motivates him year after year. 'We must prioritize indigenous communities,' he urged. 'Given their enduring trials and tribulations, they deserve to feel rooted in this land, this wilderness as well.'
Arriving at our second stop, Baixa Grande, we shared the space with other trekkers. Even so, evenings remained cozy, gathered around campfires with Tav strumming his guitar. Our closing day featured a breezy 5-kilometer (roughly 3-mile) stroll, allowing a leisurely morning. Departing under a flawless sky, the bone-white sand and azure pools dazzled more than ever.
Amid the splendor, I welcomed our Jeep pickup signaling the end. We jogged over in mock exhaustion, exiting the park's core to trace the shoreline to Atins. Boarding up, I glanced back—we'd conquered 36 kilometers, but soon, no evidence of our passage would linger. Here, dunes reshape, lagoons ebb and flow, footprints fade. The sole enduring element? Transformation—and the generations who've adapted to thrive within it.
In a world where travel destinations often face the clash of admiration and overuse, does Lençóis Maranhenses' growing fame spell doom or opportunity? Is it fair for luxury developers to encroach while locals struggle for recognition? What do you think—should tourism be tightly regulated here, or left to evolve naturally?
