Agricultural activities are quite conspicuous throughout the first part of this trail. Then, you reach la Crête Corossol, which offers some fine views ahead of the star attraction: the panoramic, 360-degree viewpoint.
Hiking trail colour: yellow
The start of the trail is located around twenty metres below the parking area, so head back down for a short while. The sign showing the start of the trail reads "Trace Vallée Beaugendre - Grande Rivière".
The trail climbs steadily and is well marked. Be aware not to mix it up with other unofficial tracks. Head to the left of a cabin and follow the trail that goes straight into the forest. At the intersection on Crête Corossol, turn left towards the "Trois Crêtes". Walk along the ridge, paying attention to the prominent slopes. When you get to the shelter, a few metres further along the trail, the views can be magnificent on a clear day. You can sleep at the shelter or carry on with the hike towards Piton de Bouillante and the Mamelles to the north, or even join up with the Merwart or Victor Hugues trails (routes will be available online soon).
If not, turn around to return to the same route. You can also head back by la Vallée de la Grande Rivière des Vieux Habitants (see sheet "Trois Crêtes from la Vallée de la Grande Rivière").
