In Le Petit-Bornand, in the commune of Glières-Val-de-Borne, head down towards the church and then up the Route de Morat. Park your car just before Morat.
(S/E) Take thePR® trail, starting point marker. Follow the well-marked path, which is sometimes a little steep. You’ll reach the Chalet du Lova.
(1) Continue along the winding path, then cross the Ravin des Fringles before reaching a crossroads of paths.
(2) Leave the Lavouillon path on your left and continue straight on, following the Ruisseau de la Fontaine Froide. You’ll soon reach another junction.
(3) Keep to the left along the stream, then head up to the right and head straight for the Tinnaz chalets (pronounced ‘Tâne’). Continue on to reach the bank of the stream.
(4) You will then enter the beautiful pastureland of the Tinnaz plateau, where several hundred heifers are grazing for the summer. Continue the climb until you reach a stream (see § Practical Information), which is usually dry. Turn right and you will very quickly come to a crossroads of paths.
(5) Follow the signposts to the right to reach the Col du Freu.
(6) Turn left, heading due west, onto a path that is sometimes steep. Do not continue towards La Balme or Bellajoux. Take care at a section crossing a recent rockfall. Emerge onto the ridge; follow it to reach the summit of La Roche Parnal.
(7) Descend a steep path to arrive just above the Col du Câble.
(8) Follow one of the paths heading east: there are several running parallel to one another. Then, via a slight circular loop, return to the crossroads you passed on the way up.
(5) Retrace your steps along the route you took on the way there to reach the crossroads before the Tinnaz chalets.
(4) Turn left, pass the chalets and continue on to reach the junction you also passed on the way there.
(3) Then head into the woods, following the route back in the opposite direction to the one taken on the way there, until you reach the car park on the Route de Morat (S/E).
