Unirea salt mine in Slanic Prahova is a mix between the hand of man and nature’s wonders. It is the largest salt mine in Romania and in Europe and it was transformed into a health centre for the treatment of pulmonary diseases in saline air, at 210 meters deep. It is also open for tourists that just want to see how the salt was extracted and to admire the largest chamber of the saline, which is 55 meters high. The access to the Unirea salt mine is made with minibuses since the elevator is broken.

In the afternoon, after the salt mine, you will have the opportunity to walk in a lunar landscape, visiting the Romania muddy volcanoes. Before arriving there you will have a break for lunch in a recommended restaurant. After enjoying your lunch it is time to see the biggest Muddy volcanoes in Romania.

The muddy volcanoes in Berca, Buzau county, form the biggest area of this type in Romania. Read more about them here. The muddy volcanoes tour includes Paclele Mari and Paclele Mici, two geological and botanical reservations. They both have small volcano-shaped structures caused by the eruption of mud and natural gases that come from 3000 meters deep. Near these volcanoes the soil is sulfurous and salty, so the scenery looks like a desert or like the Moon’s surface.  That makes it a special place.
