  • Forêt de Mare Longue is a unique primary tropical forest. This remaining section of lowland tropical rainforest is a true botanical treasure-trove. After 2 centuries of intense deforestation, less than 7% of the original tropical rainforest remains in Reunion Island, mainly located in Saint Philippe. The primary forest of Mare Longue, which miraculously survived, is the richest tropical forest in Reunion Island. Thérésien Cadet (1937-1987), professor at the University of Reunion Island, was the first to study in depth the vegetation of the Forêt de Mare Longue. In the early 1970s, during the field inventories in preparation for his thesis, he drew the attention of the managers of this forest on the need to preserve this jewel of Reunion’s natural heritage which was at risk of being transformed into a plantation for wood production. A stone tablet pays homage to him at the start of the path. With this path, the ONF has created one of the most beautiful botanical trails in Reunion Island, in what is the first biological reserve on the island, and you can read the many information panels along this route.

How to reach the start
From the north or west, head for Saint Philippe, and 1 km after passing Le Baril, and 100 metres after the Puits des Anglais, turn left into Chemin de Ceinture. If you’re coming from the east, pass Saint Philippe and Mare Longue, and on leaving the village of Souffleur d'Arbonne, turn right onto Chemin de Ceinture. Continue along this road for 1.7 km and go straight on at the junction with the concrete road coming from the right. Then, 150 metres further on, take the junction which leaves straight to the left - the forest road of Mare Longue. After 1.3 km and a few turns, you’ll see the car park for the botanical trail on your left.
