Saint-Denis: the active volcano of French Réunion Island

Capital of the French overseas department of Réunion, Saint-Denis remains the departure point for one of the world's most active volcanoes.

A car remains essential to explore the island.

The Piton de la Fournaise, one of the world's most active volcanoes, erupts regularly, offering natural spectacles often safely visible from designated vantage points.

A short walk from the center, the Barachois district, with French colonial buildings, remains the historic heart of Reunion's capital.

Continuing toward the interior, one reaches the Cirque de Mafate, a volcanic cirque accessible only on foot or by helicopter, isolated from the rest of the island.

Toward evening, local markets in Saint-Denis sell spices and Creole products, reflecting the island's multicultural heritage.

Piton de la Fournaise, among the world's most monitored and active volcanoes, erupts on average once a year, attracting scientists and tourists worldwide to observe the phenomenon safely.

Cirque de Mafate, with no paved roads, remains one of the few inhabited places in France accessible solely on foot or by helicopter, with isolated villages untouched by civilization for centuries.
