    Stop At: Vulcanii Noroiosi (Muddy Volcanoes), Paclele Mari, Berca 127035 Romania

    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.
