In the northern reaches of Brazil, the unique and fragile landscapes of the Lencois reward the adventurous.

Her name, he told me, was borderline biblical: Maria dos Milagres, or Maria of Miracles.

By the time I met Souza, Id been plotting a visit for several years.

Others traced the origins of the nearly 400-square-mile ecosystem as far back as the last Ice Age.

The Lencois and the surrounding region seemed as extraterrestrial and uninhabitable as Saturn.

Until recently, tourism tended to be as hardscrabble as you might imagine.

In 2023, Lencois Maranhenses National Park recorded more than 250,000 visitors, a 150 percent increase over 2020.

Turning around, still grinning, I saw or was I imagining it?

Arriving at the Lencois still takes time, effort, and planning.

I asked what he planned to do when boats could no longer get to his restaurant.

We dont worry about those things around here, he said, with a laugh and a shrug.

Today, its hardly on the tourist radar at all.

Finally, after three days of near-constant transit, we arrived at La Ferme de Georges, in Atins.

Its hard work, he said, but I get to live in a way that brings me joy.

Their presence made for a refreshing break from the usual barricade that luxury hotels erect between locals and guests.

By next year, La Ferme intends to build the Peixinhos a permanent space alongside the beach house.

Tourism may have changed Atins, but at the hotel, the feeling of a village persisted.

Though people continue to live in the park, authorities tellingly call the area the Primitive Zone.

It opened in May 2023.

It looked like the edge of the earth.

It was the best meal I ate all week.

Life in Travosa is very precarious, she went on.

We dont have basic infrastructure for health or education.

If we could open things to tourism, all of that might change.

She paused for a moment.

Weve been here longer than the park.

Wed like to create new opportunities.

In Travosa, though, it still represents hope.

Shortly after, she met Souza while washing clothes on the banks of the Rio Alegre.

(Halfway through he asked if we were close and I told him Yes!

she recalled with a huge laugh.

We kept that game going for the next six hours!)

Souza remembers that first trip fondly.

With the oasis behind us, we walked east into the wind.

A glimmer of sand smudged the distant dunes into a lavender sky.

For me, it was proof that humanity can thrive, even in the least likely of places.
