Réunion is a region of France, just like the other four overseas departments. It is an important part of the French Republic. Réunion is one of the European Union's most remote areas, and it is part of the eurozone. [4] The only places in the Southern Hemisphere that are part of the eurozone are Réunion and Mayotte, which is also a French overseas department.

The Guide de la Réunion 974 application is absolutely necessary while traveling around the island of Reunion. It provides information on the places of recreation, accommodation, and rest on the island of Reunion, as well as hikes, the schedules of cinemas on the island, and a list of the island's pharmacies.
