​Why only spend the day exploring when you can venture out at night too? This nocturnal excursion gives wildlife spotting a mysterious and magical twist, all in one of the Northeast’s most spectacular locations: the Parnaíba River Delta. Board a speedboat in moonlit Parnaíba and meander among the mangroves down the delta’s many channels. On the way, your tour guides will shine their torches on some of the hundreds of species that inhabit this protected natural environment. An abundance of crabs and caimans. This a truly unique opportunity to observe the life that plays out after dark in the world’s third largest river delta.
