Park in the Plan de la Lai car park shortly after the Plan de la Lai refuge when coming from Beaufort.
(S/E) Head immediately north-east on theGR®5, which is also part of the Tour du Beaufortain route.
The path passes by the Chalets du Plan de la Lai.
Cross two footbridges.
(1) After the second footbridge, leave the Rocher du Vent trail on your left and continue on the trail that enters the mountain pasture. The slope gradually becomes steeper, and the trail crosses several mountain pasture tracks before arriving at the Chalet de Bel Air (2,145 m).
(2) At the ruined chalet, the trail is joined by another trail coming from Rocher du Vent.
From the chalet, continue along theGR® towards Col de La Sauce. The slope on this section of the route is less steep.
(3) At the pass (2,307 m), you can see the Refuge de la Croix du Bonhomme in the distance. Turn right to walk along the Crête des Lodges, where the slope becomes steeper again.
The route alternates between sections along the ridge and sections carved into the slope.
After passing close to the summit of the ridge (2538 m), the trail descends to the Col de la Croix du Bonhomme (2408 m).
(4) From the pass, climb a little higher to the Refuge de la Croix du Bonhomme (2,433 m).
(5) From the refuge, continue north to the boundary marker (2,479 m).
(6) Descend via the same route to the car park (S/E).
