Le Trou de Madame — 'Madam's Hole' — is a naturally warm sulphurous spring whose playful, folkloric name points to a long local tradition of oral history associated with the site. Such informally named springs are often among the most authentically local thermal experiences, untouched by commercial development and appreciated primarily by those with knowledge of the territory. The warm, mineral-rich water emerges naturally from the earth, offering bathers a spontaneous and unmediated geothermal encounter.

Insider tip — Le Trou de Madame (The Lady's Hole) is a folk-named sulfurous spring in the Landes near the Adour river, where geothermal activity along the Pyrenean foothills fault system brings moderately warm sulfurous water to the surface. The whimsical local name reflects the oral tradition attached to this spring, long used by local women for skin treatments. The flat Landes pine forest surrounding the site provides easy access on foot or bicycle along the network of forest tracks crossing this vast, sparsely populated region.
