This is known as Tange Reghez Waterfalls ( Reghez Valley Waterfalls), consist of total of about 40 to 60 waterfalls, flow from the source to the bottom in this beautiful gorge. At the bottom of each waterfall, a nathural pool with a depth of several meters has been formed, which has added to the beauty of the path.
