The starting point for the hike is in Sewen, at the edge of the village, in a car park signposted in the village.
(S/E) Retrace your steps for about 200 metres and cross a bridge on the left.
(1) Immediately after the bridge, take a path marked with a blue rectangle that runs alongside the stream coming from Lake Sewen.
The path continues, moving away from the stream and entering the edge of the woods, with a view of part of Lake Sewen.
(2) Immediately afterwards, pass in front of a wayside shrine, then leave the path that crosses a bridge and branches off to the left.
(3) Shortly afterwards, you will come to a fork and turn right to follow the path marked with a blue triangle. After a few bends, you will arrive at the Ferme-Auberge de Baerenbach. Pass in front of the reception building and continue straight ahead following the same signs. After about 100 m, leave the path on the right and take the one on the left.
(4) You will come to a three-way junction. Take the path on the right, marked with a blue rectangle. At the next junction, continue straight ahead. The path will take you to the Ferme-Auberge du Gresson Moyen. Pass in front of the house, do not take the path on the right, but follow the path that continues straight ahead, following the same signs.
(5) You will arrive at Lac du Grand Neuweiher, with a view of the inn on your left and the lake in front of you. Follow the path along the right bank of the lake, from where you will have a view of Lac du Petit Neuweiher. Continue along the large lake, turning left and then away from it as you climb.
(6) Continue right on a path with the same markings, which climbs steeply with closely spaced switchbacks. After leaving the woods, the path opens onto a meadow.
(7) You will then have a view of the Haute Bers refuge, but do not go there just yet. Take the path on the right. It will take you to the Rocher du Corbeau, a popular climbing spot.
(8) You will arrive at Lac des Perches or Sternsee, which you will follow along the right bank.
(9) The trail leads to the Col des Perches, where several trails start. Follow the one furthest to the left marked with a red rectangle (GR®5) and continue to the edge of the forest with a view of the meadow you crossed earlier. Follow the edge of the forest and pass behind the Haute Bers refuge.
(10) Shortly after this, continue along the trail in the same direction (Ballon d'Alsace). Make a detour to see the viewpoint over the Grand and Petit Neuweiher lakes. The trail arrives at the Col des Charbonniers.
(11) At the pass, do not turn left onto a path marked with a blue triangle, but continue for about 400 m until you reach another crossroads.
(12) At this new crossroads, follow the path that branches off to the left, marked with a blue triangle, until you reach the fork in the path you took on the way there.
(4) Turn right to stay on this trail; the path arrives at Alfeld Lake.
(13) Cross the dam via the footbridge and, just before the end, take the steps on the left. At the bottom of the steps, follow the tarmac road on the left, which eventually joins the road linking Sewen to Lake Alfeld. At this point, turn left into the forest and, after about 100 metres, after a bridge, take the path on the right.
This path, marked with a blue rectangle, joins the fork in the path you took on the way there.
(3) Continue straight ahead on the same path as on the way there to return to the starting point (S/E).
