“Aulus-les-Bains is located at the head of the Garbet river valley and beneath the Guzet-Neige ski resort some 35 km south-east of Saint-Girons and 25 km south-west of Tarascon-sur-Ariège at an altitude of 750 metres. Access to the commune is by the D8F road which branches from the D3 west of the commune and follows a tortuous route to the village before continuing by an even more tortuous route to join the D18 in the east. The D32 road comes from Ercé in the north to the village. The commune is mountainous and heavily forested with large areas in the south above the snow line.
The village is best known for its thermal springs and spa complex. There are several Belle Époque buildings with some still offering hotel accommodation. The village is very popular in winter for skiing and in the summer for walking and cycling. The local beauty spot and waterfall, the Cascade d'Ars, is a one-hour walk from the village. Cyclists can climb the Col de Latrappe or the Col d'Agnes directly from the village.” Wikipedia
