Praia do Gunga, Beach in Roteiro, Brazil

Praia do Gunga is a beach located between the Atlantic Ocean and Lagoa do Roteiro, bordered by coconut palm groves. The shoreline extends for several kilometers with ocean waters on one side and calm lagoon waters on the other.

Praia do Gunga lies in the municipality of Roteiro, on the southern coast of Alagoas, about 36 kilometres by road from Maceió, at the mouth of the Lagoa do Roteiro where the lagoon system meets the Atlantic. The Instituto do Meio Ambiente de Alagoas keeps two monitoring points in the area, one on the ocean strip and one in the estuary. In 2019 environmental teams recorded oil fragments at Gunga during the spill that reached Brazil's Northeast and took part in clean-up along the Roteiro coast.

The name Gunga also labels the Mirante Gutemberg Breda on the AL-101 Sul, a lookout over the coconut grove, the beach and the lagoon mouth. From Barra de São Miguel, boats cross to the beach, and small boats and kayaks are rented there for trips to the nearby "natural aquarium".

The beach lies about 36 km by road south of Maceió, in Roteiro, at the mouth of Lagoa do Roteiro. It can be reached by car along the AL-101 Sul, or by boat from Barra de São Miguel. The Mirante Gutemberg Breda on the AL-101 overlooks the coconut grove, the beach and the lagoon bar. Near the cliffs, the Alagoas fire service advises safety equipment and specialist guides.

The water colors here shift throughout the day as ocean tides mix with lagoon water, shifting between deep blue and emerald tones. This daily color play occurs because of the unusual position between two different water systems.
