Lençóis Maranhenses: The Desert with Water [2026]
Lençóis Maranhenses is a 155,000-hectare expanse of white dunes with freshwater lagoons in Maranhão — the only desert in the world that has water. A UNESCO World Heritage Site since 2024, the park is accessible from three bases: Barreirinhas, Santo Amaro and Atins.
The phenomenon: From January to April, rains fill the lagoons between the dunes. From May to August they're 100% full under blue skies. From September onward, they dry out gradually.
When to Go
The Standard Answer
Jun-Aug: lagoons 100% full, zero rain, guaranteed sunsets. Peak tourist season.
The Insider Answer
Apr-May: lagoons are ALREADY 90%+ full, virtually no tourists, low-season prices.
| Month | Lagoons | Tourists | Price |
|---|---|---|---|
| Apr-May | 90-95% | Very low | $ |
| Jun-Aug | 100% | Very high | $$$$ |
| Sep | 75% | Medium | $$ |
| Oct-Dec | Drying up | Low | ⚠️ |
About April-May: There can still be brief rain showers and sunsets don't always cooperate. But the lagoons are spectacular — fuller, more vivid colors — and you'll practically have them to yourself.
