Park in the car park by the roundabout at the A48 exit. Head in the opposite direction to the roundabout and you’ll soon reach the tarmac path on the embankment.
(S/E) Take the embankment on the right; it separates the River Isère on the left from the Canal de la Vence on the right. Continue in a north-north-westerly direction, passing the Voreppe toll station. You’ll reach a junction at the Étang de la Roize.
(1) Ignore the track on the right and continue along the Voie Verte (VV); you’ll reach a ford clearly marked by a sign. This ford is at the confluence of the River Isère and the Canal de Vence. Walk back a few steps to reach the junction of two tracks.
(2) Turn right to take the road first, then, a few metres further on, the dirt track closed off by a barrier prohibiting access to motor vehicles. Continue along this track with the Canal de Vence on your right until you reach the Étang de la Roize
(3) Cross the canal’s spillway via the footbridge, then, a few steps further on, cross a second footbridge over the canal itself to rejoin the track you took on the way out.
(1) Take the track on the left and stroll back to the car park.
