(S/E) Departure and return to the car park near the Saint-Quirin lake.
(1) Take the RF, marked with a blue disc and yellow ring, eastwards to the intersection with a yellow ring trail on the left. After a fairly steep slope for two hundred metres, the trail joins a first RF, which you should take to the right for about a hundred metres, then it turns left. This is a very pleasant trail, leading first to a crossroads and then continuing (marked with a yellow ring) opposite towards the Croix Guillaume crossroads.
(2) At Croix Guillaume, take the path on the right at a right angle (GR®5red rectangle) onto a path that leads to the archaeological site of Croix Guillaume. This site is well worth a visit. There are numerous information panels along the route. Allow about fifteen minutes for the visit.
Retrace your steps and take the red rectangle marked trail. Continue to the "Les Quatre Chemins" crossroads and continue on the RF opposite until you reach a fork.
(3) At the fork, continue on the RF for "Belle Roche Bas".
(4) Take the path on the right (there is a sign at the entrance to the path) to reach the Belle Roche cave. Don't hesitate to take a quick detour to the cave, which offers a magnificent view of the nearby peaks. After visiting the cave, retrace your steps and take the path to reach the platform above it.
As you leave, take the path heading west for a few metres (red rectangle). It then makes an inverted S-shape to reach
(5) Leidenstein Pass. Before the pass, take a short detour to the "Jules" fountain, 300 metres round trip (signposted).
After the pass, find the blue disc marked trail. Continue straight ahead.
::6: Leave the RF by taking the path on the right and cross "Le Saveux", a site of Celtic importance where, if you stray from the path, you will discover many traces left by our ancestors. Stay on this trail to reach the Bacelles cave, which sheltered young girls from the region during the Thirty Years' War. Continue to the intersection.
(7) The path descends sharply to the left (St Quirin via the retirement home), blue disc. Join the tarmac road near the pumping station and take this road on the left for about 800m to reach a fork.
(8) After the bridge, turn right at the hairpin bend and continue along the tarmac road for about 800m.
(9) Then take the path on your left (red ring). This very pleasant path crosses the Haute Chapelle forest road and leads to Lamperstein.
(10) Turn right and follow the Haute Chapelle circular trail, passing several turnoffs on the right and left.
(11) At a place called "Haut du Bouge", take a small path that climbs uphill, marked with a yellow ring, for a few dozen metres to join a wider path.
::12: At the table and bench, turn right.
(13) Make a detour to the Gallic pond (marshy area - information panel). Continue to
(14) AR towards the viewpoint
(15) The Parc rock kiosk, which offers a magnificent view of the village and the surroundings of Saint-Quirin. Shortly afterwards, take a short detour to the cup-marked stone.
(16) Return to the path and continue to the left.
(17) Turn right to reach the Haute Chapelle de St-Quirin. A visit to the chapel is a must. Head back down towards the abbey. After your visit, return to the forecourt, take the Rue de la Garinette and follow it down to the Rue du Moulin, then turn left and walk alongside the stream.
(18) Pass in front of the miraculous fountain of Saint Quirin. Continue along the stream to reach Rue du Général de Gaulle at the town hall.
(19) Turn right and walk 300 metres, then turn right onto Rue d'Alsace and continue along this street until you reach the lake (S/E).
