Alfeld Lake car park
(S/E) Climb up to the lake and cross the dam. Once at the end, turn right onto theGR® 531 (marked with a blue rectangle) towards the Refuge d'Issenbach (828 m). You will come to a fork in the path.
(1) Look for the Blue Rectangle trail on the right, which will be the return route, and continue straight ahead on the trail that runs alongside a small canal and then joins a track. Follow this track to the left for about 500 m until you reach a trail junction.
(2) Leave this track and take the path on the left which climbs up the valley (marked with a blue rectangle) and crosses a moraine. Further on, the path widens and arrives at a crossroads.
(3) Ignore the path branching off to the right (marked with a blue triangle) and continue straight ahead to the Issenbach Refuge, where you can enjoy a picnic on a beautiful grassy terrace facing the Sewen Valley.
(4) Then take a faint grassy path in the middle of the meadow, which descends to the left at the foot of the refuge (bordered by a wooden fence) and quickly joins the Blue Triangle path. Follow it downhill to the left for 150 metres.
(5) As this route has been modified from the IGN map, turn right to join a track suitable for vehicles and follow it to the left. This new route will take you, after passing through a wooden fence, to the Baerenbach farmhouse inn.
(6) Before the farm, in the left-hand bend leading to it, leave the track and take the grassy path on the right (Blue Triangle) which descends to the bottom of the valley at the junction with the Blue Rectangle path.
(7) Follow the signs to the right towards Lake Alfeld. The path runs alongside the Seebach Gorges, then crosses a track and continues straight ahead to rejoin the GR®531 and the initial fork.
(1) Turn left. Ignore the lake dam and continue straight ahead to go around it, following the Blue Ring trail. You will come out on the Route du Ballon d'Alsace (D466).
(8) Follow it to the left until you reach the car park (S/E).
