Băile Herculane is a historic spa town in Caraș-Severin County, in the Cerna Valley of southwestern Romania. One of the oldest thermal resorts in the world, it has drawn visitors to its hot mineral and sulphurous springs since Roman times. Set in a dramatic gorge between forested mountains, the town blends Belle Époque spa architecture with a long tradition of balneotherapy.
Insider tip — Baile Herculane is Romania's most storied thermal resort, occupying a narrow gorge of the Cerna River in the Domogled-Cerna Valley National Park. The Romans built elaborate baths here dedicated to Hercules, and the springs they used still flow at up to 60°C before being tempered for bathing. The crumbling grandeur of the Habsburg-era casino and bath pavilions adds a haunting, picturesque quality; the forested canyon is a biodiversity hotspot with endemic Cerna Valley lizards and rich orchid meadows on the surrounding limestone ridges.
