“Surprise Cave” is located under Dubossary. The cave was formed as a result of tectonic shifts of the earth’s crust in blocks of sedimentary limestone. It has three entrances, two of which are very complex, and represent a communication network of cracks in the earth’s crust, crevices and cavities up to 5 meters high, up to 1.5 meters wide, which in some places expanded and formed roomy halls (“Golden Ring”, “Elevator ”,“ Metropolitan ”,“ Cinema ”, etc.), as well as deep wells, which are sometimes even dangerous. Its total length is approximately 1700 m. It is a horizontal cave in two- three levels. It is very dangerous in the cave; it is forbidden to go down alone there.
