History and Geology of Slănic Prahova Salt Mine: From the Old Salt Pits to Unirea Mine
Salt mining in this area has a long history. Find out more on Wikipedia.ro
The main attraction for visitors is Unirea Mine. Masterfully designed, it consists of 14 chambers with a trapezoidal profile.
Technically, the mining work was carried out with engineering precision. The method used was undercutting and drilling, followed by breaking out the rock, techniques that ensured the stability of the ceiling and walls. The mine's safety relies on massive pillars (support columns) and the natural cohesion of the salt.
For geology enthusiasts, the mine's walls are an open book. You can see bands of varied colors, in shades from white to dark gray, which indicate different mineralogical characteristics and the layers deposited over geological eras.

Visiting Slănic Prahova: Facilities, Sports Grounds, and Access
Underground access has changed over time. While the “cage” (the mine elevator) was used in the past, today tourists are taken into the heart of the salt mountain by minibus, through a tunnel that leads straight into the mine. Once down below, visitors discover a huge space equipped with modern facilities.
Images of the salt mine interior
The salt mine has sports grounds (soccer, volleyball, tennis), children's playgrounds, and even a dedicated go-karting area.
The generous space between the old salt pits makes it possible to host sports competitions and events, and the acoustics are exceptional.
Although there are other famous salt mines in Romania, such as Praid Salt Mine (closed), Cacica Salt Mine, Ocna Dej Salt Mine, or Târgu Ocna Salt Mine, Slănic stands out for the huge volume of salt excavated (2.9 million cubic meters in Unirea Mine).

Above ground, the resort rounds out what it has to offer with its salt lakes: Baia Baciului, Baia Verde, and Baia Roșie, formed by the collapse of old salt pits.
