Terme Dobrna is Slovenia's oldest working thermal spa, with over 620 years of continuous tradition, located in the tranquil village of Dobrna. The spa's therapeutic foundations rest on three natural healing factors recognised by the Slovenian Ministry of Health: thermal water, curative mud, and turf. The complex houses what is claimed to be the largest outdoor thermal pool complex in Slovenia, comprising ten swimming pools, alongside sauna worlds, and the Arbora Spa offering a comprehensive treatment menu including classical, Thai, Indian, Ayurvedic, chocolate, honey, and Mediterranean massages, as well as lymphatic drainage, thalasso rituals, body shaping, and facial rejuvenation therapies. A Diagnostic and Rehabilitation Centre staffed by specialists in gynaecology, orthopaedics, cardiology, neurology, and other disciplines adds a strong medical dimension to this historically rich spa destination.
