Ocnele Mari Salt Mine: underground microclimate near Vâlcea

The Ocnele Mari Salt Mine is a visitor and wellness area in one of the worked-out levels of an active salt mine in the small town of Ocnele Mari, 8 km from Râmnicu Vâlcea in Vâlcea County, close to the Olt valley. It is run by the state company Salrom. Salt has been mined here since prehistoric times: finds show work as early as the Neolithic, and in 1960 archaeologists uncovered on the hill above the town the Dacian fortress of Buridava, mentioned by Ptolemy. Under Prince Constantin Brâncoveanu the Ocnele Mari mines became an important source of revenue, and the new mine at Cocenești was begun in 1993. When extraction on level +226 ended, it was turned into an underground visitor complex, open to the public since 2009.

Natural healing resources

The main factor is the stable microclimate of the salt mine: according to Salrom, the air inside stays at about 13–15 °C and the humidity at about 50 % all year round. The air in salt workings is free of pollen and laden with salt particles; such conditions are used in speleotherapy — spending time in an underground microclimate. The striped, layered salt walls are a sight in themselves.

What is treated

Salrom describes the mine as a place for rest, leisure and health and has set up areas inside for relaxation and exercise "to enhance the therapeutic effects". The operator does not publish a list of indications, and this is not a medical facility with a doctor on site. The microclimate of salt mines is traditionally used as a supporting measure for chronic respiratory conditions, but whether it suits you is for a doctor to decide. The one official requirement: children under 3 visit on the recommendation of a family doctor or paediatrician, otherwise under the accompanying adult's responsibility. This information is for reference only and is not medical advice: a doctor prescribes the course and procedures after a consultation.

What to do in the mine

• Down by bus. Visitors are driven from the surface building into the mine by buses that run about every 30 minutes.
• Underground leisure: volleyball, basketball, football and tennis courts, billiards, mini-karting, minigolf, an ice rink and children's play areas with swings and slides.
• A museum with exhibits from the earliest times to the present, and the underground church of Saints Barbara and George.
• Repeat visits: a pass for 5 entries within 14 days suits those who want to spend several hours a day in the microclimate.
• The "Cafea la sare" café and, at weekends, a self-service line with hot meals.

Romanian roads require the rovinieta e-vignette. From the town of Râmnicu Vâlcea it is about 8 km to the mine.

Nearby

The mine combines well with the Vâlcea spas: Băile Govora with its iodine-bromine waters, Călimănești-Căciulata with thermal pools in the Olt gorge and Băile Olănești with its drinking springs. In the mountains above the Olt gorge rises Cozia (Ciuha Mare), and the Cozia, Govora and Dintr-un Lemn monasteries are close by.
