On the D900, in the village of Larche, park in the Town Hall car park.
(S/E) Follow the D900 towards Meyronnes, leave the village and look out for the start of a track on the right.
(1) Turn right onto it and head uphill, passing close to an aerial, then continue uphill until you reach a group of blockhouses. This group of blockhouses, the Larche Outpost, is the largest defensive structure on this walk.
(2) Carry on climbing until you reach a flat area; look out for a rock on the right with a door cut into it. Head towards it – this is Le Truc. It has been hollowed out and fitted with a firing slit.
(3) Return to the path, passing close to the ruins of the Colombier farm, which was destroyed by the Germans. Climb up following the track, then, at a hairpin bend, leave the track and follow the path along the hillside to reach a flat area. Here, look out for another blockhouse, Strongpoint 1893, which played a very important role on 20 June 1940 in holding back the Italian attack.
(4) Turn left onto the path leading uphill over a small ridge – this is theGR®5– and you will very quickly reach another junction of paths.
(5) Leave theGR® and continue first on level ground, then climb briefly up a ridge before finally traversing the hillside to a new blockhouse, known as Strongpoint 2018.
(6) Continue along the hillside path until you reach a track and theGRP®, at the L’Ausse Blanche junction.
(7) Turn almost 180° to the right, follow the Rouchouse stream, then reach the Génie Dam, where only a few stakes, tied in pigtails, remain to hold up the old barbed-wire barrier.
(8) Continue downhill to the Prés Bas crossroads. Keep straight ahead on theGRP®, reaching the footbridge over the Ravin du Combal and the end of a track.
(9) Ignore this footbridge and continue straight on along the wide track that forms part of theGRP®, marked with yellow and red signposts. At the end of the descent, you’ll reach Larche and the town hall car park (S/E).
