The Parc Thermal in Bourbon-l'Archambault, Allier, draws bicarbonate water emerging at 38°C. The site combines indoor and outdoor pools with a sauna and hammam, set within the wooded grounds typical of this Bourbonnais spa town.
Insider tip — Parc Thermal at Bourbon-l'Archambault is the landscaped thermal park at the heart of this medieval spa town in the Bourbonnais, where bicarbonate waters have attracted royalty and literary figures since the 17th century — Madame de Sevigne famously wrote letters from her cure here. The park features shaded promenades around historic spring pavilions, and the nearby 11th-century castle of the Dukes of Bourbon frames the skyline. The water is among the mildest and best-tolerated thermal waters in France, with no sulfur edge.
