With its fragrant scrub and valley vineyards, the mountainous Corbières region assures visitors a pleasant experience. It is however its Cathar heritage which continues to fascinate. Known as the "Five Sons of Carcassonne", the citadels protecting this French borderland still cast imposing silhouettes on the horizon. A tour taking in Aguilar, Termes, Peyrepertuse, Quéribus and Puilaurens will introduce visitors to the surrounding landscape and explain the history of this austere region.
