There are a few parking spaces in front of the town hall, and a parking lot just behind. It's a good starting point for hiking, but we prefer the Via Ferrata parking lot at the exit of the village.

In the heart of Chapareillan, the Saint-Blaise and Notre-Dame church blends Romanesque, Gothic, and modern elements. Remodeled several times, it retains a massive square bell tower and a sober interior. From the forecourt, the view opens onto the reliefs of the Chartreuse massif.
