0 km - You arrive at Bord Martin, where the start of the trail is on the right side of the car park when you’re looking at Ravine Savon in Mafate.
0.2 km - Head down into this gorge of Ravine Savon, then the rate of descent increases after 200 metres. Be careful with this tricky and very slippery section, covered in longoses.
1.0 km - The descent becomes easier, then you reach a junction. If you miss it, it doesn’t matter because the path that heads off on the left is closed because it’s too dangerous. It used to let you join the Scout trail. Continue straight on.
1.7 km - After a slight incline then a short but steep descent, the trail alternates between fords and slippery sections.
2.3 km - You cross the last ford, marking the end of the descent of Ravine Savon. Now you head up to the Augustave Channel.
3.1 km - A forbidden trail leads off right to the catchment in the Augustave Ravine. Continue straight ahead, past the wooden shelter with the sheet metal roof on the right, and then further on, pass by the heliport used to bring in the materials necessary for constructing the footbridge, down to the left. After crossing a small ravine which is almost dry, you arrive at La Fenêtre (the Window). Admire the scenery before starting the descent of the Grande Passerelle.
3.3 km - Turn around and admire the ONF’s technical prowess in achieving this feat of construction.
3.6 km - Be careful in this section as the stones are covered with a thick layer of silt. This is an extremely slippery place (“Soap Ravine” deserves its name).
4.0 km - The trail follows the Marianne footbridge.
4.2 km - The precipice is sometimes hidden on the left by the vegetation, so be careful and watch where you put your hands and feet.
5.1 km - You’re approaching Aurère and the path on the cliff side is at times narrow with a handrail firmly anchored into the wall.
5.3 km - In front of you is Petit Rein, a narrow passage, not very long but with a drop on either side. On the left you can admire Ravine Savon, and on the right Bras des Merles.
5.6 km – Passing through the forest of filaos, you arrive at a junction. A trail heads off right towards Bras des Merles, but you continue left towards Aurère.
5.8 km - You descend the ridge behind the Le Poinsettia gîte, and you’re overlooking Aurère.
6.0 km - You arrive at the last junction, just at the entrance to Aurère, near the ONF offices.
