Ardovská Cave
It is located to the south-east from Ardovo, on the south-western edge of the Silická Plateau. The cave was formed in the Middle Triassic pale Wetterstein limestones by waters of occasional water course, which sinks underground at the end of wide blind valley leading from Dlhá Ves, resembling an edge karst polje. During the times of snowmelt or intensive rainfall when the ponors are not able to drain all the water, the dolines in front of the cave are flooded by temporary lake. The waters flow now through occasionally flooded lower parts of the cave and spring on surface on the other side of the Veľký vrch. Shapes of river modellation can be observed in several places – oval parts of passages and ceiling channels.
