Cathar Trail: Castles of Vertigo

Six days on the Cathar Trail, from the Mediterranean to the Aude Pyrenees, discovering the "citadels of vertigo". The route links Port-la-Nouvelle to the fortresses of Quéribus and Peyrepertuse, perched on rocky spurs, all the way to Puivert. It's a history-laden hike, following the Cathars who took refuge here in the 13th century, across garrigue, gorges and fortified villages. The route is physically demanding, with steep climbs to the castles; bring good shoes, plenty of water (the garrigue is dry) and sun protection. Spring and autumn are ideal, as summer can be crushing. Each fortress offers a breathtaking panorama that rewards the effort.
