The walk begins at the picnic area.
Head off left to the first wooden footbridge. A wooden arrow, marked "Sentier Nature" will point you in the right direction.
(1) Then head left over a second footbridge, with a second arrow "Sentier Nature" pointing the way for you to discover the island of the Né valley. Afterwards retrace your steps to marker No.4, which can be found to your left once you leave the island. (this will allow you to discover 3 boards explaining the site's flora and fauna.)
Head due west-south-west and follow the stream to marker No.9 (2). Then turn right to walk the length of the poplar plantation where marker No.10 is located. Turn right again and make for marker No.16, which is located a few paces away from the start point of the trail.
Return to the picnic area by way of the footbridge on your left.
