The starting point is the car park at the far end of the lake, next to Rue du Parlement de Navarre.
Outside the summer holidays, this car park is free of charge.
(S/E) Take the path that goes round the lake heading south-east.
(1) After crossing the stream via a footbridge, the path turns right to follow the southern shore of the lake.
(2) Turn right onto the embankment, then right again onto the pavement of the Promenade du Parlement de Navarre. Follow this path until you reach the large car park.
(3) Turn right to continue along the lake shore and turn right at the three-way junction to return to the car park (S/E).
