Another extraordinary place of interest is the balneoclimateric Resort of Bálványos, situated on the southern side of the Bodoc Mountain in the arc of the Carpathians, at 840-950 m above the sea level. The lake is situated 67 km from Sfântu Gheorghe northeastward. Due to the therapeutic qualities of the mineral waters and of the post-volcanic emanations (mofette), the resort offers to its guests ideal conditions for relaxation and treatment. Due to the volcanic and sedimentary rocks, the hydrogen sulfur and carbon dioxide emissions favored the development of numerous mineral waters, which are used for the treatment of stomach and intestinal diseases, as well as of cardiac and vascular diseases. Both the water and the gases dispose here of a relative big natural radioactivity. The Bálványos resort of our days came into being when the three spa resorts grew together. The oldest one, situated at Bálványos pass, was known under the name of Pucioasa from Turia (the word “stink” refers to the smell of the hydrogen sulfide). The healing properties of the mineral waters from Bálványos Resort are well-known for a long time, being used by the local inhabitants for the treatment of numerous diseases. Their exploration according to the literature of balneology began in 1938. The natural factors are: mineral water: sulphuric, carbonic, chloride, ferruginous, calcerous, hypotonic; mofette with carbon dioxide emissions with post-volcanic activity, with special equipping in the interior of the hotel; sedative, protective and strengthening bio-climate.
