Park in the car park of the Barioz Nordic area. The route is very well marked, with numerous signs and posts, and is numbered 1. The start of the circular is common to circulars 1, 2 and 3.
(S/E) Set off to the right of the foyer along the cross-country ski trail. About a hundred metres after the start, the route branches off to the left and leaves the cross-country ski trail.
Continue to follow the markings. The trail crosses the cross-country ski trail twice and, after skirting the small Lac de Crèvecoeur (under the snow), arrives at a fork between circular loops 1 and 3.
(1) Turn left and continue to another fork between circular 1 and 2.
(2) Turn right and continue to follow the markings for the circular path 1. The path continues to climb to a large clearing and then enters the forest again.
Once you reach the ridge, the route crosses a cross-country ski trail and leads to another fork with another circular loop (circular 4).
(3) Turn left and follow the path that runs along the ridge towards the north, offering a beautiful panorama. Once on the plateau, head towards the refuge, passing between the cross-country ski trails.
(4) At the refuge, leave route number 1 to go to Crêt du Poulet. To do this, pass to the left of the refuge and climb straight up to the cross, then go to the two orientation tables. Return to the refuge via the same path.
(4) Back at the refuge, you will find route number 1. Turn right and follow the cross-country ski trail. Shortly after the ski lift arrival point, the route turns left and descends towards the start, crossing the cross-country ski trail twice before rejoining the circular number 2.
(5) At this point, continue downhill to the Nordic area (E).
