Spa towns, thermal baths and spas in the Grand Est

💡 January: Off season for most cure resorts, which are closed in January. The most realistic options are the thermal-water complexes in Nancy and Amnéville; check opening times before you go.

💡 February: The season tentatively resumes: in 2026, the Contrexéville baths reopened as early as 7 February. For the other resorts, you have to wait until March; Nancy and Amnéville remain safe bets.

💡 March: Reopening month: in 2026, Morsbronn and Niederbronn welcomed their spa guests from mid-March, Bains-les-Bains on the 16th, Vittel on the 23rd and Bourbonne on the 30th. In 2027, Bains-les-Bains has announced an opening on 22 March.

💡 April: All the cure resorts are open: a good time for a cure or mini-cure before the summer crowds, as the spa parks turn green again.

💡 May: Spring is ideal for exploring Plombières-les-Bains on foot, with its Second Empire heritage and balconies, combined with a treatment session at Bains-les-Bains or Vittel, less than an hour’s drive away.

💡 June: June combines mild weather with still-moderate visitor numbers. Thermapolis, which reopened at the end of May 2026 after fifteen months of works, unveils a new outdoor pool of around 200 m².

💡 July: In summer, the outdoor pools come into their own, in Amnéville as at Nancy Thermal. Book treatments in advance: July is a busy period in the Vosges resorts.

💡 August: In very hot weather, opt for morning treatments. Northern Alsace (Niederbronn, Morsbronn) and Bourbonne let you combine a cure with cooler forest walks.

💡 September: September is often a good compromise: resorts still open, the school holidays over, and the Vosges forests inviting for walks between treatments.

💡 October: The last real month of the full season. In 2026, the national “Immersions Thermales” open days opened participating establishments to the public on 24 and 25 October; look out for the next edition.

💡 November: Closures follow one after another: in 2026, Bains-les-Bains on 7 November, Contrexéville on the 15th, Bourbonne on the 21st and Vittel on the 28th. After that, turn to Nancy or Amnéville.

💡 December: Off season for cures. A relaxing day in warm water is still possible at the Nancy and Amnéville centres – a nice complement to a visit to the Christmas markets in Nancy or Metz.
