Exploring the Unirea Salt Mine in Slanic Prahova

The tour’s first stop takes visitors into the Unirea Salt Mine, located at 208 meters deep on an area of 53,000 square meters. This underground site is the largest salt mine in Europe and is now open for public visits, offering a glimpse into a working mine that has been accessible since 1970. The expansive 14 rooms are shaped like trapezoids, with a notable opening at the base measuring 32 meters and total excavation volume of 2.9 million cubic meters of salt.

Inside, the mine functions as a sanatorium for asthmatic patients, benefiting from its natural ventilation and steady underground temperature of 12°C. Visitors can walk through the galleries and chambers, marveling at the scale of this underground salt world. It’s an impressive sight that combines natural mineral deposits with the infrastructure of a former industrial site. While the admission fee of 55 RON is paid on-site, the tour guides lead you through the corridors, explaining the history and significance of this salt mine.

The two-hour visit is a highlight for many, especially those interested in geology, industrial history, or simply seeking a cool, atmospheric environment. It’s worth noting that this stop is a must-see for those who appreciate natural mineral environments and large-scale underground spaces.

The Berca Muddy Volcanoes: A Geological Show

Following the salt mine, the tour heads to the Berca Muddy Volcanoes, a geological and botanical reserve renowned for its mud volcanoes. These structures resemble tiny volcanoes, rising just a few meters high, formed by eruptions of mud and natural gases that originate from 3,000 meters deep underground. As gases escape, they carry salty water and mud to the surface, creating bubbling, cone-shaped formations.

The eruption process is dynamic, with the mud expelling from the volcano mouths as bubbles of gas rise, then drying into solid, conical structures that look remarkably like real volcanoes. Visitors observe this continuous bubbling activity, which is cold to the touch, coming from deep within the Earth’s crust. The landscape’s unusual appearance makes it a favorite for photography and geology enthusiasts alike.

This stop typically lasts about one hour, allowing ample time to explore the area and admire the natural spectacle. Since the admission fee of 20 RON is paid in cash, visitors should come prepared. The muddy volcanoes offer a rare glimpse into subterranean geological processes and create a landscape that feels almost otherworldly.

Seamless Logistics and Comfortable Transportation

One of the notable features of this tour is the all-inclusive logistics. The pickup service ensures door-to-door transfers, eliminating the need to arrange taxis or public transport. The air-conditioned vehicle equipped with Wi-Fi guarantees a comfortable ride throughout the 11-hour adventure.

The professional guide provides insightful commentary in English, enhancing the experience with background on the geological processes, history, and significance of each site. The tour also offers free bottled water to keep everyone hydrated during the day. This convenience and personal attention make it an appealing choice for travelers who value flexibility and personalized service.
