Crossing from Brazil into French Guiana is a unique experience, as you are not just entering another country but an overseas department of France. This means you are, by extension, entering the European Union. The currency changes from the Brazilian Real to the Euro, the official language becomes French, and the cultural atmosphere shifts from South American to a distinct Afro-Caribbean-European blend. This border is defined by the wide Oyapock River, and for many years, the only way to cross was by a small ferry. Today, there is only one official crossing: the impressive Oyapock River Bridge.
This modern, cable-stayed bridge connects the Brazilian city of Oiapoque, in the state of Amapá, with the French Guianan town of Saint-Georges-de-l’Oyapock. An interesting piece of history is that the bridge was completed in 2011 but, due to bureaucratic delays concerning insurance and staffing on both sides, did not officially open to traffic until 2017. When planning your crossing, be aware of the time difference; French Guiana is one hour ahead of Amapá state in Brazil. You will also encounter full customs and immigration checks, as you are entering the EU’s jurisdiction, so ensure your passport and any required visa are in order.
