Paddling in Parque Nacional do Superagui

Parque Nacional do Superagui sits on the northern coast of Paraná, where the Serra do Mar meets the sea and the land dissolves into one of the largest estuarine-lagoonal complexes in South America — the Lagamar.

The park's roughly 34,000 hectares are built almost entirely of water and the edges of water: tidal channels, mangrove creeks, bays, restinga lagoons, and the open Atlantic. There is no whitewater here.

The paddling is flatwater, tidal, and coastal, shaped by mangrove corridors and the rhythms of the estuary.

The park takes in Ilha do Superagui, Ilha das Peças, Ilha do Pinheiro, and Ilha do Pinheirinho, along with the Vale do Rio dos Patos on the mainland side.

The Canal do Varadouro — the channel cut in 1953 that made Superagui an island — is one of the defining waterways of the park, connecting the interior channels and allowing navigation through what was once a 4-kilometer land crossing.

Paddling it puts you inside the transition between Atlantic Forest and tidal flat, with the kind of quiet that comes from a place with no road access.

The Rio Araçaúba threads through the island interior, the sort of dark-water mangrove river where the canopy closes overhead and tidal influence governs your timing.

Near the village on Ilha do Superagui, a river of clean, dark water meets the sea at the Barra da Praia Deserta — a natural put-in or take-out depending on how you've read the tide.

The 38-kilometer Praia Deserta stretches along the ocean side of the island; paddlers running the coastal edge need to account for Atlantic swell and the exposure that comes with open-coast travel.

One documented multi-day route crosses from São Paulo state into Paraná along the park's remote coastline, covering empty channels and stopping in small fishing villages — a 4-day trip through a landscape where the only sounds are wildlife and water.

The park is part of the broader Lagamar Mosaic, and the estuarine system connects to the bays of Paranaguá, Cananeia, and Iguape, giving experienced coastal paddlers a much larger context to work within. The park is managed by ICMBio.

Access is primarily by boat from Guaraqueçaba.

Check directly with ICMBio for current visitation rules before launching — this is a UNESCO World Heritage Site and Biosphere Reserve, and the protections that keep the mangroves intact are the same ones that govern how you move through them.

The water here doesn't ask much of your technical skills. It asks for attention to tide, weather, and the fact that you're moving through one of the most intact stretches of Atlantic Forest coast left on the planet.
