Aquensis

Aquensis stands on the Rue du Pont d'Arras in Bagnères-de-Bigorre, in the Hautes-Pyrénées; according to the operator's legal notice it is run by the company SEMETHERM DEVELOPPEMENT, at "Etablissement Thermal 65200 BAGNERES DE BIGORRE". The bath adjoins the town's Grands Thermes and the casino.

Aquensis writes that its waters are rich in trace elements and particularly in calcium, magnesium and sulfates, and that the water is "Extraite par forage à une température de 50 °C" — drawn by borehole at 50 °C — then cooled by a system that avoids any mixing, so that it reaches the pools in its natural state. The operator publishes no borehole depth, no total mineralisation in mg/L and no analysis figure; the named constituents are given qualitatively. The pool water temperature is not published either.

The Espace Détente is built in wood, Pyrenean marble and daylight. Its Grand Bassin covers 300 m², is fed with thermal water and is animated with misting jets, a water curtain, swan-neck spouts and alcoves with bubble beds, jets and counter-currents, with a 20 m central swimming corridor running alongside it. Next to it the Piscine Détente carries hydromassage stations and Aqua musique, relaxing music diffused under the water. The Espace Hammam is laid out as a series of vaulted rooms lined with Pyrenean marble benches, with a tea room, a treatment cabin and mint tea served. The Terrasse Détente is a wooden decking terrace with whirlpool baths and loungers looking out over the spa town, the Bédat forest and the Pyrenean summits; two traditional Finnish saunas flank a large central shower there. Beyond the détente area the building holds a treatments section, an aquatic relaxation section — currently not open for individual bookings — and a gym and fitness section.

Aquensis opens seven days a week, Monday, Wednesday, Thursday, Friday and Saturday from 10:30 to 20:00 and Tuesday and Sunday from 12:30 to 20:00, with bathers leaving the pools fifteen minutes before closing and reception closing at 19:00 each evening; the bath closes once a year for a technical shutdown. Children are admitted to the Espace Détente from the age of five and must be accompanied by an adult between five and fifteen. The operator does not publish an opening year for the building.
