Slănic (Romanian pronunciation: [sləˈnik]) is one of the 14 towns of Prahova County, Romania, historically and currently known as a salt extraction center, as well as a spa town, with salt lakes. Two villages, Groșani and Prăjani, are administered by the town.
Although technically incorrect, the compounded name Slănic Prahova is also being used, especially in other parts of Romania. This alternative name was probably generated to help discern between Slănic and another Romanian town, Slănic-Moldova.
The town is famous for its salt lakes (or Băi): The Shepherd’s (Baia Baciului), The Green (Baia Verde) and The Red (Baia Roşie) Lakes, as well as for the Old (Salina Veche) and New (Salina Nouă) Salt Mines. While salt is still being extracted from the New Salt Mine, the Old Mine is open to the public now, being used as a spa, amusement center and museum of the salt mining industry. International contests of Indoor Model Aircraft Flying (Modellism) take place annually in the upper level (Mina Mihai) of the Old Mine.
