Parking available at the Col du Sattel.
(S/E) With your back to the entrance to the holiday camp building, leave the return path on your left and set off along the steeply ascending path opposite. At the end, turn right and walk for about a hundred metres.
(1) Take the path on the left to explore an underground gallery. Then head for the pass between the Petit and the Grand Reichackerkopf.
(2) At the pass, take a short detour to the left (and back) to see a memorial to a soldier.
(2) On your return, head back towards the Col du Sattel, the starting point of the walk, via the track on the right, marked with a Blue Disc, to begin the second circular route. At the junction, just before the pass, turn right for a few metres.
(3) At the junction, turn right and take a pleasant forest track. Follow the Red Rectangle with a White Bar markings, which skirt the Reichackerkopf to the north. Cross a gully and reach a bunker.
(4) At the blockhouse, leave the Red Rectangle with a White Disc and take the path on the right which climbs up, quickly joining a wide path marked with a Blue Disc.
(5) Take this path straight ahead; it goes round the south side of the Reichackerkopf and rejoins the small pass between the Petit and the Grand Reichackerkopf.
(2) Continue along the track and return to the Col du Sattel (S/E).
