The most substantial part is in fact the first half of the ascent of the Col du Coq, on the Saint-Nazaire side. After 6.5 km of climbing, shortly after the tunnels, you have the choice of going left on the D30E, towards the pass, or, if you are already tired or want to do the Petites Roches plateau (or even the Chartreuse balcony as far as La Palud), staying on the D30 towards Saint-Pancrasse and then Saint-Hilaire. In both cases, you'll enjoy magnificent views over the valley.
La partie la plus consistante est en fait la première moitié de la montée du col du Coq, versant Saint-Nazaire. À 6,5 km de montée, peu après les tunnels, on a le choix entre aller à gauche sur la D30E, vers le col ou, si on est déjà fatigué ou si on souhaite faire le plateau des Petites Roches (voire le balcon de Chartreuse jusqu'à La Palud), on reste sur la D30 vers Saint-Pancrasse puis Saint-Hilaire. Dans les deux cas, on pourra profiter de magnifiques points de vue sur la vallée.
