The route starts from the Pont Pérignon car park. Throughout the route, the path is very well maintained and clearly signposted, with signs at every junction.
(S/E) Take the footbridge and follow the mountain bike track.
(1) At the first junction, take the track on the right. On the first part of the route, follow the red and white GR® markings if in doubt.
(2) Take the track that winds sharply uphill to the left and heads towards a junction.
(3) Head left again to reach the ridges. From here, the panoramic views come one after another, each more spectacular than the last: this is the most magnificent section of the route. Continue to a junction.
(4) Turn left: no particular difficulties to report. Most of the ascent has already been completed at this point. You’ll reach another junction.
(5) Turn left again. There are still about thirty metres of ascent left before you begin the descent.
(6) Leave the GR® by taking the ‘Sentier de la mine du mois de mai’ on the left. The signposts indicate the direction of Pont Pérignon anyway, so if in doubt, you can follow them. After a fairly steep descent, you’ll reach the junction with a mountain bike track.
(7) Turn left to follow this gentle, flat track
(8) Carry on straight ahead; do not take the road on the right, which no longer exists when the lake level is high anyway. You’ll return to the junction where you started.
(1) Turn right, cross the footbridge again to return to the car park (S/E).
