[Closed] Les Houches GR5

Can anyone help me with some routefinding for Les Houches, either with directions or ideally a gps file?

I've seen a few people online in various forums say how great the GR5 trail is down from the Bellevue gondola. Steep, switchbacky, Cedric Gracia's favourite trail etc. Sounds great, but when I look at the GR5 on the IGN map it's just a road going down from Col de Voza under the Maison Neuve chairlift. It's definitely not singletrack. So is there a different GR5? Can anyone help me find it?

Thanks!
