The site is a mountain valley with a stream and its tributaries covering an area about 200 x 400 square meters. It is the limestone mountainous area in the north with five meters high waterfall and smaller waterfalls down below. Source of the water is from cavities or caves in the dark grey Ordovician limestone mountains with calcium carbonate dissolution. The tufa is formed on the rock surfaces when water evaporates from the lime-rich waters, leaving calcite to crystallize. The tufa-coated rock surface with running water is not slippery. Water from the main waterfall is diverged into many creeks falling onto many levels of terraces and finally converged into a single stream.
