Regardless of visa requirements, all travelers entering Brazil present specific documents to immigration officials upon arrival.
The official currency is the Brazilian Real (BRL), symbol R$. Costs on the island, while sometimes higher than the mainland due to logistics, can be managed with smart strategies.
