Morne Langevin, Mountain summit in Saint-Joseph, Réunion Island, France

Morne Langevin is a summit in Saint-Joseph, Réunion, reaching 2,415 metres along the mountain rampart that overlooks the sources of the Langevin River from the Plaine des Remparts. Its upper slopes are bare grey-brown volcanic rock cut by vertical gullies, while green vegetation covers the lower slopes. The top is wide and nearly level.

Morne Langevin lies on the rampart that overlooks the sources of the Rivière Langevin, the watercourse that runs from the Piton de la Fournaise massif down to the Sud sauvage. The summit, on the territory of Saint-Joseph, reaches 2,415 metres along this wall above the Plaine des Remparts. It is reached by a hiking trail that follows the Rempart des Sables from the Col du Pas des Sables.

The summit lies on the communal territory of Saint-Joseph, the island's southernmost commune, and is reached by a hiking trail that follows the Rempart des Sables from the Pas des Sables pass. The route runs along the cliff edge above the sources of the Rivière Langevin, the river that flows from the Piton de la Fournaise massif down to the island's south coast.

Hikers can reach the summit by following marked trails that start from Pas des Sables and require sturdy footwear and weather-appropriate gear. Visitors should expect changing weather conditions and allow sufficient time for both the climb and descent.

From the summit, visitors can see directly into the Remparts Plain and spot the Langevin River sources carved deep into the volcanic rock below. This view reveals how water has carved through the black stone landscape over vast stretches of time.
