By car, drive to the La Balme car park after passing through La Clusaz. Shuttle buses run to La Balme from La Clusaz or Saint-Jean-de-Sixt.
(S/E) Descend a flight of steps leading to the path providing access to the Combe de Fernuy, the start of the route. Follow this path uphill to reach the junction with a wide track.
(1) Leave the path leading to the Aiguille des Calvaires slopes on your right and continue straight ahead, heading south-east. Cross a well-marked path, then continue, veering left to head east. Begin a diagonal ascent leading to a small, unnamed pass providing access to the Combe de la Creuse at an altitude of 1971 on the IGN map.
(2) Continue to the right heading south-east. Reach an altitude of 2200 m.
(3) From here, you can see the summit clearly; continue up a steeper slope to reach the summit of the Porte des Aravis.
