Barbotan-les-Thermes is a spa in the Gers department of south-western France. Barbotan forms part of the commune of Cazaubon, and the town of Cazaubon is some to the south-west. Barbotan lies on the Route nationale 524 (N524). It is approximately north-west of Auch, south-east of Bordeaux, west of Bordeaux, and from Paris. The N524 forms part of the Itinéraire à Grand Gabarit, a route which has been modified to allow its use by the oversize road convoys conveying body sections and wings of the Airbus A380 airliner, and several upgrades were made to the road through Barbotan to this end.
