Park at Col du Calvaire, in the car park of the Lac Blanc winter sports resort.
(S/E) From the car park, pass under the high-voltage power lines and start by following a marked Green Ring trail which climbs north-east through grassland, then into the woods, and reaches the Petite Tête des Immerlins.

Between (1) and (2): diversion imposed by the Vosgiens club due to a wildlife sanctuary. It is therefore impossible to reach the Tête des Immerlins. However, the diversion is very well signposted.
(1) Following the Green Ring markings east and north-east, the path descends and then climbs slightly towards the Tête des Immerlins.
(2) At an elevation of 1,216 metres. Caution: the descent can be tricky due to the condition of the path, which consists mainly of slippery rocks. The path leads to a small Duchesne Cemetery dating from the 1914–1918 war.
(3) This is also a junction of several paths. Go straight on along the path that climbs, now following theGR®®5marked with a Red Rectangle. The path climbs steeply towards the Tête des Faux, a pile of rocks topped by a cross.
(4) Continue along theGR®®5towards the south-east. Note the blockhouses and remnants of the First World War along the way. The path descends and leads to the Roche du Corbeau.
(5) This is also a former bunker from the 1914–1918 war. Continue to follow the Red Rectangles as you descend along a fairly steep path leading to the Étang du Devin.
(6) Head towards the Gîte de l’Étang du Devin. Just before the lodge, immediately after a small chapel, a path branches off to the left.
(7) This is still theGR®®5; it climbs to the left, then, after a wide left-hand bend, about 200 m further on, you’ll reach a junction with a path marked with a Green Ring.
(8) Turn left onto this path; it climbs quite steeply and eventually joins a wider forest track at a bend.
(9) Take this path to the left, continuing south-west and always following the Green Ring markings. The path then turns south and reaches another junction. Continue along the main path, now marked with a Yellow Ring.
(10) Keep heading in the same direction. Further on, the forest track reaches afirst Y-junction. Keep left in the same direction; after a few hundred metres, theGR®® joins this forest track from the left.
(11) Continue straight on; the path begins a gentle descent then turns right to go round the Petite Tête des Immerlin. Pass the Tinfronce ski runs; the path climbs slowly, then steeply at the end as it joins the car park of the ski resort at Col du Calcaire (S/E).
