📍 Réunion is an overseas department and region of France located in the Indian Ocean, east of Madagascar and southwest of Mauritius. It is part of the Mascarene Islands and has no land borders, being surrounded entirely by the Indian Ocean.

Réunion’s geography is defined by its volcanic origin, featuring rugged mountains, deep valleys, and dramatic landscapes within an area of about 2,512 square kilometers (970 square miles). The island is dominated by two major volcanic massifs, including the active Piton de la Fournaise, one of the most active volcanoes in the world, and the extinct Piton des Neiges. Its terrain includes steep cliffs, cirques, and lush tropical vegetation, supported by a humid climate. The coastline is mostly rocky with some beaches and coral reef areas. Réunion’s natural environment and location have shaped its role in agriculture, tourism, and scientific research.
