Thermes Callou Vichy

Thermes Callou is one of the thermal facilities operated under Vy Resort Thermal & Spa, the rebranded successor to the 170-year-old Compagnie de Vichy. It sits on Rue Callou in central Vichy, a town built around nine mineral springs and recognised as a UNESCO World Heritage site in 2021.

The spa is adults-only and built around hydrotherapy: a thermal pool and a hydrotherapy circuit using Vichy's mineral water, rather than a menu of standalone treatments. Access is by reservation, and the place operates on a seasonal thermal calendar rather than running year-round without interruption — Thermes Callou is slated to open from mid-February to mid-November for the 2026 season.

Standard hours run 7am to 6pm Monday through Friday and 7am to 4pm on Saturday; it's closed Sundays. Pricing sits in the upscale bracket for the region, in line with a destination thermal spa rather than a budget day-spa stop. The broader Vy Resort complex also houses longer medically supervised thermal cures (the 18-day conventionné programs mentioned on the operator's site), so staff and facilities are set up for both short wellness visits and extended treatment courses — worth keeping in mind if you're trying to figure out whether a single day pass fits into the schedule or whether you need to book further ahead for a specific slot.

For exact day-pass pricing, treatment options and current-season opening dates, it's best to confirm directly with Vy Resort, since the site structure and offer have recently changed under the new branding.
