The trail is marked all the way by a Blue circle.
(S/F) The start point is at the Neuweg allotments in Saint-Louis.
Start by following the path also marked with a Red triangle that leads to the "small Alsatian Camargue”. Soon we leave it, turning left onto a small path along which there are a dozen fruit trees planted. Turn right twice again passing a further ten or so common trees.
(1) At the bench, turn left onto the trail to the meadow.
(2) Turn left and go alongside the meadow and reach a large forest road and take it right. Ten metres before reaching the paved road of the gravel pit, fork onto a small path to the right that leads to the first of the three drinking water catchment areas.
(3) Follow right path to the right that leads to the second catchment area, then reach a small Y-junction where the small path that takes you left to see dozens of dead trees uprooted by the storm of 1999 covered by foam.
(4) At the crossroads, take the right path also marked with Red triangle alongside hedges planted during the creation of the circuit that takes you back to the starting point (S/E).
