About Thermes de Spa
Thermes de Spa, Belgium is a paid thermal spa resort on the Colline d'Annette et Lubin hillside above the city of Spa, in Liege province, at the address Colline d'Annette et Lubin, 4900 Spa. The facility draws water from its own natural Clementine spring at 33 degrees Celsius across 800 square metres of indoor and outdoor pools. The thermal tradition of Spa dates to the 16th century and the town's thermal sites were listed by UNESCO in July 2012. Visitors aged 15 and over are admitted. Entry is paid.
Pools, Saunas, and Facilities
The 800-square-metre pool area includes heated indoor and outdoor pools with bubble beds, massage jets, geysers, and a waterfall feature, all fed by the Clementine spring. Separate textile and naturist sauna and steam areas are both available: each has its own saunas and hammam ceremonies. Peat baths and traditional balneotherapy treatments continue a practice rooted in the mineral-rich, iron-bearing composition of Spa's spring water. Carbonated copper baths using water from the Marie-Henriette spring provide a historic bathing experience. Relaxation areas include aromatherapy zones, infrared lamp rooms, and aquagym sessions. A cafe and restaurant with pool terrace views are on site. The facility is reached from the town by funicular.

Suitability & Accessibility
Who Thermes de Spa Suits
Thermes de Spa suits adult visitors aged 15 and over seeking a thermal spa experience rooted in centuries of balneotherapy tradition, with particular appeal for those interested in peat baths, carbonated copper baths, and the naturist sauna areas that are less common at other Belgian facilities. The UNESCO listing and the long royal history of Spa give the site a cultural depth beyond a typical wellness venue. Visitors who prefer textile-only facilities can use the standard sauna and pool areas without entering the naturist zone, so both preferences are well served in one visit. For those seeking hot springs near Spa Belgium with a genuinely historical and therapeutic dimension, this is the primary option in the Ardennes region.
Planning Your Visit
Three-hour and full-day admission options are available; three hours is sufficient for the pools and one or two sauna sessions, while the full-day option suits those who want treatments and a more leisurely pace. Carbonated copper baths and peat baths are booked separately and should be reserved in advance as availability is limited. The outdoor pool attracts larger numbers at weekends; arriving early is advisable. Visitors who want to use both the textile and naturist zones should allow extra time. The funicular ride from town provides panoramic views over the Spa valley and is part of the experience.
Safety & Etiquette
Safety at Thermes de Spa
Thermes de Spa is generally safe for adult visitors aged 15 and over, operating as a managed facility with staff throughout the pools, saunas, and treatment areas. The Clementine spring pools are maintained at 33 degrees Celsius; visitors should allow a short acclimatisation period on entry and should exit the water if they feel lightheaded, particularly in warm outdoor conditions combined with heated pool water. The carbonated copper baths are individually supervised treatments and the peat baths are conducted with staff present throughout.
Sauna, Hammam, and Etiquette
The facility has separate textile and naturist zones; visitors enter their chosen zone on arrival and remain within it for the duration of their sauna time. Standard sauna etiquette applies: towels are used as bench mats, sessions should be limited in duration, and cooling between rounds using the shower or plunge facilities is strongly recommended. Hammam ceremonies are timed sessions; arriving a few minutes early is advisable to secure a place. Peat baths involve heated mineral-rich organic material; visitors with skin conditions, open wounds, or cardiovascular conditions should seek medical advice before using this treatment. Medical conditions including pregnancy warrant a consultation with a doctor before using heated pools, saunas, or any thermal treatments. Valuables should be stored in a locker. Advance booking for copper baths and peat treatments is required, as these have limited daily availability and walk-in slots are rarely available at weekends.
