The geological and botanical reservation covers 60 hectares.
The reservation consists of two sections, Pâclele Mari and Pâclele Mici.
The muddy phenomenon starts deep down, at a depth of 3,000 meters.
Gases erupt and travel to the surface through underground layers of water and clay.
They bring to the surface salty water and mud.
The cones of these miniature volcanoes do not reach more than five or six meters in height.
While some of the volcanoes erupt continuously, others do so at random times.
During hot summer days, the crusts display yellow salty formations.
The only two plants that survive in this area are Nitraria Schöberi and Obione Verrucifera
When visiting, it is forbidden to touch the volcano cones.
The mud volcanoes were first discovered by Frenchman H. Cognard in 1867, during oil explorations.
The area was declared protected in 1924.
