Hylas is a mixed libertine sauna and hammam on the Avenue de Verdun in Valence. It has been an established name locally for years, and now opens as a mixed libertine club seven days a week, with women and couples admitted alongside everyone else. Themed evenings run on Fridays and Saturdays.

It sits inside a shopping centre, and the centre's gates close at half past seven in the evening — worth knowing before arriving late. Parking is free.
