0.15 km - You quickly reach the edge of the rampart, and the trail begins to plunge into the ramparts, heading off towards the left.
0.4 km - The path zigzags quickly downhill.
0.5 km – You reach a long straight line downhill to the left and you have already lost 200 metres of altitude.
0.9 km - The descent, which had eased off by heading to the right, continues in earnest, but the view of the Rivière des Remparts is worth taking your time to enjoy.
1.1 km - The bottom of the river is near, and the trail heads off in a long straight line to the left.
1.4 km - After a few tight turns, the descent of the rampart ends with a short straight line, then enters the undergrowth. You have lost 400 metres of altitude to reach the bottom of the Rivière des Remparts, at the place known as Mapou. Now a gently sloping descent along a path traced along the bottom of the Rivière des Remparts begins.
2.3 km - The trail approaches the right rampart, and you reach a steeper slope. The vegetation changes and becomes more sparse, giving way to the grandiose landscape of the valley of the Rivière des Remparts before you. You begin the descent on an old lava flow.
3.2 km - You approach a waterfall, and the descent on the lava flow ends with a sharp bend.
4.4 km - With the gentler slope, the vegetation gets higher, and you pass near the bottom of a ravine on your left. Be careful: the bottom is 10 metres below.
4.9 km - Pass by the Sosthène Grondin commemorative plaque, swept away by the waters here in 1987, and then the sign for the place known as 'Le Paturage - Alt 1000 m'.
5.4 km - The Davedinde waterfall on your left is dry, but the drop is deep. The slope gets steeper and you pass into a forest of filaos (coconut palms).
6.0 km - The slope is now gentle. On both sides of the path, huge chokas, pineapple flowers, low stone walls, filaos and bamboo make up the landscape.
6.1 km - You arrive at a fork where a sign indicates Bras de Caron. Continue straight on to Roche Plate.
6.9 km - You cross the Rivière des Remparts which is dry and go up the other bank. A new fork heads off left towards Bras de Caron. Continue straight on towards Roche Plate along the low stone walls.
