From Orschwihr church, take Rue de l'Automne along the cemetery and continue straight ahead. Park in the car park just before entering the vineyard and a sign prohibiting motor vehicles.
(S/E) Cross the small stream, then after about 100 metres, turn left onto the road. Then take the first left and cross the stream again. Pass a few houses, one of which has a chicken coop, ignore the path on the left and continue along the vineyards until you reach a fork.
(1) Take the left fork, keep left at the next junction, pass a cross, keeping left, and you will arrive at the start of a path.
(2) Turn left onto this well-marked path, ignore the side paths and continue to a large intersection, leaving the Chapelle du Bollenberg on your left.
(3) Turn right and continue downhill until you reach the road, which you will follow for about 250 metres.
(4) At the three-way junction, take the left-hand road, still through the vineyards. Cross a road and continue straight ahead along a dry meadow until you reach a crossroads.
(5) Turn left into the nature reserve, which is signposted at the entrance. Cross the dry meadow, keeping your bearings, and join the access road to the Domaine du Bollenberg, arriving at the Auberge du Vieux Pressoir.
(6) Continue straight ahead, leaving a parking space for motorhomes on your right, and take the next road on the right. Go uphill, then, after a right-hand bend, descend gently towards a wooded area and the start of a path on the left.
(7) Take this small path that climbs to the left. Cross the meadow at the top of the hill, then descend, continuing straight ahead until you reach the bottom of the descent and the intersection with a track.
(8) Turn right and then left, heading south-southeast and continuing through the vineyards. Return to the large crossroads you encountered on the way there.
(3) Turn right to return to your starting point (S/E).
