Although the hamlet of Saint Marcellin, where the village was originally located, still has a square tower castle which may have been the archbishop's residence, Châteauroux les Alpes, which was once the largest rural property belonging to the Embrun family is today no more than a large village whose grey rather austere houses stand on a slope overlooking the Durance.

Châteauroux les Alpes benefits from being one of the points of entry to the Ecrins National Park, and also offers a great site for white water sports with the famous Rabioux wave, formed where the torrent meets the Durance.

Moreover, the Rabioux valley is a site not to be missed, for its Cascade de la Pisse waterfall, bringing a touch of coolness in an impressive, rather oppressive landscape dominated by the cliffs of La Gueste.

Also worth a mention are the Demoiselles Coiffées, a series of rock formations ressembling fairy chimney stacks, several thousand years old, formed by the erosive action of rainwater on sloping argilaceous terrain.
