An afternoon discovering a few singles above Bernin and St Ismier. I followed the route: Crolles -> Ch. des Communeaux -> Manival -> Tour d'Arces -> No Name -> Plat -> Cote Bonne -> l'Arguit -> Manival -> Pierre Champ Bertin
The No Name is a great discovery. Technical but not too much and easy to follow. The Pierre Bertin has one or two steep sections with steps that require good technical skills. None of it is overly exposed.
