The most spectacular route is the one via the Nan gorges, then via Malleval-en-Vercors. In a league of its own.

This cannon, cast in 1843 at the National Foundry of Saint-Gervais, was shipped to the island of Bourbon to ensure its defense. The Department of Réunion presented it to Mr. Vaudeville, Prefect of Isère, who handed it over to the Commune of Saint-Gervais on July 7, 1973. https://fr.wikipedia.org/wiki/Fonderie_royale_de_canons_de_Saint-Gervais

Listed among the Most Beautiful Villages in France, Saint-Antoine-l'Abbaye surprises with the richness of its medieval heritage. The Gothic abbey church overlooks a collection of cobbled streets, half-timbered houses, and terraced gardens.

Between Isère and Vercors, Saint-Marcellin has long prospered thanks to trade and its famous cheese. Its old town center preserves stone facades, narrow passages, and a few beautiful bourgeois houses.

A small village in Isère nestled at the foot of the Vercors, Rovon preserves several discreet monuments from its rural past. There, you'll come across a renovated Romanesque church, old stone farms, and a few wayside crosses. A village to discover along its narrow streets and trails.
