Overview

Join us on an unforgettable journey through two of Romania’s most fascinating natural attractions.

Our first stop is the Slănic Prahova Salt Mine, one of the largest salt mines in Europe. Located 208 meters underground, this colossal mine impresses with its cathedral-like chambers, constant temperature of 12°C, and natural air rich in salt aerosols—known for their therapeutic properties.

Marvel at salt sculptures, enjoy games and exhibitions, or simply breathe in the healing air of this underground wonder.

Next, we head toward the Mud Volcanoes, a rare geological phenomenon where gas eruptions push up salty mud, creating a lunar-like landscape. Located in Buzău County, this natural site offers a surreal experience—tiny craters bubbling with cold mud in a barren, dramatic setting that feels out of this world.

Whether you’re a geology enthusiast, a photographer, or just looking for a unique escape, this tour promises memories that will last a lifetime.

Unirea Salt Mine
  • 2h
  • Admission ticket not included
Slanic Prahova Saline is the largest salt mine in Europe. Now the old mine is currently open to the general public, being used as a leisure place. Slănic Prahova Saline is located at a depth of 208m, on an area of ​​53,000sqm and was opened for visit after 1970. The saline consists of 14 rooms, in the form of a trapeze, having an opening at the base of 32 meters, the tray, 10 meters and a height of 45 meters. The excavated space is 2.9 million cubic meters of salt. Underground is also a sanatorium for asthmatic patients who are provided specialized medical care. The ventilation of the mine is natural, with a constant temperature throughout the year of 12 degrees Celsius. Inside salt mine we visit the Supernova Planetarium which is the largest and most performant planetarium in Romania with the largest spherical screen of 16 m diameter, max. 200 seats, 4K laser projectors, super-ergonomic armchairs. We look forward to the most fascinating immersive experience in Romania.
Vulcanii Noroiosi (Muddy Volcanoes)
  • 1h
  • Admission ticket not included
Muddy Vulcanoes is a geological and botanical reservation located in Buzău County in Romania. Its most spectacular feature is the mud volcanoes, small volcano-shaped structures typically a few metres high caused by the eruption of mud and natural gases. As the gases erupt from 3000 metres deep towards the surface, through the underground layers of clayand water, they push up underground salty water and mud, so that they overflow through the mouths of the volcanoes, while the gas emerges as bubbles. The mud dries off at the surface, creating a relatively solid conical structure resembling a real volcano. The mud expelled by them is cold, as it comes from inside the Earth's continental crust layers, and not from the mantle.
