At Les Thermes des Chênes in Saint-Paul-lès-Dax, thermal water is drawn from a borehole over 865 metres deep, emerging at 47°C and rich in sodium chloride. It feeds the making of péloïde, a distinctive thermal mud born from the meeting of hot spring water and silt from the Adour river, enriched by a characteristic blue algae found on site. The establishment sits amid greenery, near a former quarry now regrown into an oak grove.
Insider tip — The fango of Dax — a mixture of warm thermal water and local clay-rich algae — is unique in the world and protected by a PGI. A 48°C wrap that penetrates deep into the joints.
