Southeast of Castries and south of Babonneau near Piton Flore, the 5km Forestierre Trail follows the Old French Road that traverses through mature pristine rainforest. The trail begins as a gentle downward slope through dense foliage and meanders among lencens trees. Plus, there are large figtrees and ferns.
The trailhead is located about 30 minutes from Castries. There is a public minibus (5E) that runs from Castries.
