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.
