A wonderful reserve filled with picturesque natural features, but the main reason that made it one of the most famous nature reserves in the country is the water pool located in it, which is called the "Hexagonal Pond" or "Hamsushim Pond", which is a huge pond twenty meters long and 30 meters wide, surrounded by a cliff. It is composed of many hexagonal basalt columns in a unique sight that visitors will not find anywhere else. This phenomenon occurred as a result of the flow of molten lava that cooled in a slow process and formed these wonderful basalt rocks.
