High-risk zones in Tarn
The Montagne Noire, bordering Tarn and Aude, is one of the most closely monitored forest areas in the department. Its south-facing slopes are particularly vulnerable during July and August. In parallel, the narrow valleys of the Thoré and the Agout can be affected by rapid flash floods during Cévennes episodes.
💡 Good to know: the Montagne Noire is subject to prefectural closures in case of high wildfire risk. Check official orders in real time on FOSIVA before heading out for any hike.
