Berca Mud Volcanoes
The Muddy Volcanoes in Buzau county are a rare geological wonder, hidden behind Buzau mountains - they are not your regular volcanoes but rather large mud bubbles, which are formed by the earth’s natural gas erupting and leaving behind crater-shaped forms of thick clay-like mud.

Muddy volcanoes are extremely rare in Europe, which makes the Romanian muddy volcanoes a curious site, guaranteeing intrigue to any visitor - they give the area a “lunar tone”, and coupled with the lack of vegetation, the landscapes offer an amazing “out of this world” impression.
