Volcanoes look like real ones, they are just small and the nature of eruptions is different. Natural gas escaping from the depths along with water and clay.
In the region of Berca-Arbanasi there are several places with volcanoes, we visited Small Mud Volcanoes (Pâclele Mici). Please note that the visit is possible only in dry weather, as the surface is muddy.
The eruption looks like an explosion of a huge bubble.
If you put a paper boat on the "lava" it will move slowly.
