Train buffs take note! The scenic Train de l'Ardèche offers majestic views as it snakes its way along the precipitous gorges of the Doux River. The train offers three different itineraries, including options to visit the pretty mountain town of Colombier-le-Vieux or the market in Lamastre. All itineraries begin at the Tournon St-Jean station, 23km northwest of Valence. Consult the website for dates of service.
