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.
