There are two ways to approach the trail, but one makes more sense than the other. Approaching from Bel Ombre will require you to pass through several miles of sugar cane fields where you must navigate a patchwork of rugged roads. It is not difficult with a GPS though or a decent map. Access from Plaine Champagne is easy in comparison.
From Plaine Champagne:
The trailhead is just beyond the Gorges Viewpoint if you are headed in the direction of Petrin. It will be on the south side of the road. Park here an then begin descending the road. The trail consists of nothing apart from this road. Do not depart from the most prominent road/trail. Watch for wildlife. I would turn around when you reach a park outpost consisting of a group of green buildings followed by a gate. Return the same way.
From Bel Ombre:
Follow the map/gps track until you reach a large gate with a small sign that says “Please close”. Park here and pass through the gate. Immediately turn right and continue until you reach another gate marked “Please open”. Enter and then close it behind you. Walk past the green buildings and continue following the road. Do not depart from the main trail/road. Watch for wildlife. Return the same way.
