The route nobody flies over twice
The northeast corner of Brazil hides a 700-kilometre chain of dunes, river deltas and windblown fishing villages that locals package as the Rota das Emoções. Done independently it is a string of buses and shared 4x4s, and it contains the single most surreal landscape we saw in South America: rainwater lagoons pooled between white dunes at Lençóis Maranhenses.
São Luís, 1-2 days
Fly or bus into São Luís, the tile-fronted colonial capital of Maranhão. The historic centre is crumbling and gorgeous in equal measure — Portuguese azulejos peeling off reggae bars, because this is improbably Brazil's reggae city. Eat arroz de cuxá, sleep in a dorm for R$60-90, and book a van to Barreirinhas (4 hours, about R$70-90, hostels arrange pickup).
Lençóis Maranhenses, 2-3 days
Barreirinhas is the base town for the national park. Standard 4x4 tours (about R$120-150 half day) crawl over the dune field to Lagoa Azul and Lagoa Bonita for a swim and sunset — good, but the better move is staying a night in Atins, the sandy village at the river mouth, reached by a slow boat down the Rio Preguiças or a 4x4 along the beach. From Atins you can walk into the edge of the dunes with a local guide and have a lagoon entirely to yourselves, warm as bathwater, with fish that arrive nobody quite knows how. Timing matters enormously: the lagoons fill from the rains and are best roughly May through September; by December many are puddles.
Crossing the delta to Parnaíba
From Barreirinhas or Atins, shared 4x4 transfers run east through Paulino Neves and Tutóia to Parnaíba (4-5 hours of beach, dune and ferry crossings, R$100-150 — bumpy, dusty, great fun). Parnaíba is the jump-off for boat trips into the Delta do Parnaíba, one of the few open-ocean deltas in the Americas: half-day tours (about R$100) wind through mangrove channels to a dune island where thousands of scarlet ibis fly in to roost at dusk like sparks off a fire.
Jericoacoara, 3-4 days
More 4x4 hopping: Parnaíba to Jericoacoara via Camocim runs about 4 hours (R$100-130, including a river ferry where wind-battered kitesurfers share the ramp with cattle trucks). Jeri is the payoff — a village of sand streets between a national park of dunes and some of the most reliable wind on the planet. Climb the Pôr do Sol dune with the whole town at sunset, swim the Pedra Furada arch at low tide, and take the buggy day-trip to Lagoa do Paraíso, where you loll in hammocks strung in turquoise water (entry plus buggy about R$150 split between four). Kite lessons run R$150-200 an hour if the wind bug bites; July to January blows most reliably. Dorms cost R$80-130, more over New Year, when Jeri briefly becomes the most fashionable sandpit in Brazil.
Out via Fortaleza
Direct transfer vans and the Fretcar bus cover Jeri to Fortaleza in 5-6 hours (R$90-120, with a 4x4 shuttle over the dunes to the paved road at Jijoca). Fortaleza itself is a big beach city worth one seafood dinner and a night before flying out.
Costs and timing
Budget R$250-320 a day (US$50-65) — the 4x4 legs add up, so find transfer partners in hostels. Sweet spot for the whole route: June to September, when lagoons are full and the wind has started. Sunscreen is non-negotiable; there is no shade in paradise.
