0 km - Climb the concrete steps, and follow the path under the cryptomerias, leaving behind you the shelters in the picnic area.
0.1 km - A sign indicates that you’re entering the Roche Ecrite nature reserve. The cryptomerias quickly give way to the primary forest.
1.0 km - The trail winds with the Bras Sec ravine below and to the right.
1.4 km - The slope increases, and you can see fine specimens of tree ferns and calumet bamboo.
2.0 km - This part of the trail is very wet and slippery. The ONF has installed gratings and logs on the most slippery sections.
2.4 km - This passage between two very mossy walls seems to have been carved into the rock.
2.8 km - You enter an area of cryptomerias.
3.3 km - Now you’ve reached the first highland tamarinds. Several endemic species dominate this area: the great highland tamarind, the highland coloured wood trees, the calumet (small bamboo) and the fanjan (tree fern).
3.5 km - Surrounded by calumets, you arrive at the path that joins this main path on the left coming from Bois de Nèfles Saint Denis, the trail of the Pic d'Adam loop.
4.0 km - You pass superb highland tamarinds, some of them so huge it would take several people to stretch all the way around the trunk.
4.3 km - The trail heads off abruptly to the right and crosses a ravine, then the slope becomes more gentle.
4.8 km - You climb a short, steep slope.
4.9 km – You’ve reached the gîte at Plaine des Chicots. On your right is the path that goes towards Dos d'Ane following the rampart of Mafate. Continue straight ahead and follow the Roche Ecrite signs.
5.1 km - Shortly after leaving the gîte, the primary forest disappears and gives way first to small, dried-up vegetation, then to thickets.
5.8 km - You reach a junction and an un-signposted path heads off on the right. This junction is not very obvious, and if you miss it, it doesn’t matter because it’s the detour to the Mare aux Cerfs (pond) and the two paths rejoin 1 km further on. We go straight ahead. Progress is slow, mainly on lava slabs.
7.0 km - The trail is rather monotonous and vegetation becomes more sparse. You arrive at the junction marking the end of the Mare aux Cerfs detour.
7.1 km - A sign indicates that the trail that descends on the left leads to Bretagne in the highlands of Saint Denis. This path is closed.
7.5 km - Here’s a new junction. Turn right because this trail is shorter. On the left, the trail makes a detour through the Caverne Soldats. You can make the detour to visit the curious “Cavern of the Soldiers” on the way back.
8.0 km - A trail heads off left towards Salazie, Grand Ilet. Another trail descends further left still and a sign indicates Caverne Soldats. Continue on the path that climbs to the right.
8.5 km - Progress on this last slope is more and more difficult on the lava slabs, but you can see the summit in the distance and an antenna stands out against the blue sky.
9.0 km - You arrive at the antenna, and then Roche Ecrite. The exceptional panorama rewards you for your efforts. Piton des Neiges, the roof of the Indian Ocean, is in front of you. Writings, often first names, are inscribed all over the rocks around the geodesic marker of Roche Ecrite.
