(S) From the centre of the village of Mijoux, follow Rue Royale and theGR®®, then head straight up towards La Faucille. The first stage involves following the Sentier des Arts opposite. Once at the top, cross the track, then take the ski run on the left and the path that climbs left-hand way round a bend just before the source of the Vouivre.
(1) Follow this and rejoin the track on the left without any difficulty until you reach the Col de la Faucille.
(2) Go round the Petite Chaumière on the right and rejoin the road that runs between the ski pass sales chalet and the start of the toboggan run. Continue straight on. The road passes to the left of the giant zip line start point. Further on, the path climbs to the left. It winds through the forest, crosses a small bridge over a ravine and eventually emerges from the woods, just opposite the Gelinotte ski run. Join the white path on the right before passing under the ski lift.
(3) Take the path on the left towards La Vie de Chaux.
(4) Turn right, then continue straight on for 800 metres.
(5) At the junction, turn left to reach Montrond.
(6) At the summit of Montrond, follow the GR® path (red and white). Walk along the ridge.
(7) Pass the Grand Montrond and continue south-south-west. The path is undulating, with an uphill gradient.
(8) At the Pas de l'Echine, continue south and soon head south-west for the final ascent of the Colomby de Gex.
(9) Continue straight on (south-west), still along the ridges, with a beautiful panoramic view. The path is also undulating and eventually joins the white track.
(10) Continue to the left and arrive at the Col de Crozet.
(11) Descend to the right to the upper station of La Catheline. Walk along the top of it and continue on theGR®® alongthe track, then keep right at the bend before keeping left until you reach the Refuge de la Loge (E).
