Around two hours from Saint-Leu, Piton de la Fournaise is a reminder that Réunion remains an island in constant motion. Rising to 2,632 metres, one of the world’s most active volcanoes continues to shape the island’s landscape through its frequent eruptions. Its dark slopes, ancient lava flows and craters tell a geological story that is still being written. You have no doubt already seen those striking images of glowing lava splitting the Réunion night.
Before heading up towards the volcano, stop at the Cité du Volcan in Bourg-Murat. This museum traces the island’s volcanic history through interactive exhibitions for visitors of all ages.
Many hikers favour the austral winter (July to October), when temperatures are cooler and visibility is often at its best. The Route du Volcan leads you gradually into this mineral landscape. After the pastures of the Plaine des Cafres and the cryptomeria forests, the scenery shifts abruptly into the almost lunar Plaine des Sables. At the end of the road, the Pas de Bellecombe-Jacob overlooks the Enclos Fouqué, a vast caldera at the centre of which stands the Dolomieu crater.
When access is permitted, descend into the enclosure and follow the white trail markers through the ancient lava flows. Allow around five hours for the return hike: 11.6 km with a little over 500 metres of elevation gain. With every step, you will feel the power of the volcano beneath your feet.
Piton de la Fournaise can also be explored via the Route des Laves, on the east coast, where some lava flows have solidified all the way down to the Indian Ocean.
