Shooshtar Falls area is located south of Bandar Gargar Bridge and Shariati St. It is not known exactly when the site was created, but evidence suggests that it was probably built in the Sasanian period, especially during the reign of Shapur I. According to Shooshtar's book, during Ardashir Babakan (founder of the Sassanid dynasty in 224 AD), the construction of the Gargaragh River and Shapur, son of Ardashir, continued in order to bring water to the east and south of Shooshtar and boost the region's agriculture. On this creek, the Gargar Bridge was built, which not only prevented the flooding of additional waters, but also connected the city of Shushtar with its east (Masjed Suleiman and Ahvaz). Had. Inside the cascade area, there were about 40 mills, located in the north, east, and west. The mills were used for flour production. Over time, natural disasters (floods and earthquakes) and human factors destroyed most of these mills. At present, the Reza Gulab mill is being restored by the Shushtar Historical Aquatic Sites Cultural Heritage Site. And it is working.


Gisom Forest Park


One of the sightseeing areas of Gilan province and Talesh is Gisum Forest Park. The beautiful, tree-lined path overlooking the trees has created a forest tunnel that captivates every viewer.

Although Gisom only welcomes tourists in the first half of the year, it should be noted that if you fail to travel to Norouz and the first half of the year, Gisom's natural beauty is no less than spring and summer.


Desert Rig Jen


The Rig Jinn Desert in the southwest and west of the Kavir plain, from the north to the south of Semnan and southeast of Garmsar, from the west is confined to the Desert National Park and the Tangle of Darkness from the east to the junction of teachers-teachers and from the south to the north of Anarak and Shepherd. The Jinn's Rig lies within an area of ​​3 square kilometers. In other words, the Rig Jinn on the northern margin leads to Sulfur Mountain, on the eastern margin to Damghan-Jandagh Road and in the northern part to the Vergi River which springs from the Sulfur Mountain heights. The river enters the northwest-southeast direction of the Rig Genie and Mount Mawhadi is on the southern margin of the Rigger.


As it was said, "Rig Jen" is a desert region with sand dunes in the central desert of Iran and due to the large area and lack of springs or wells, in the distant past, it was not a place for passing convoys and only in recent years. , Several groups of scholars and travelers have come to the area, extending from the northwest to the southeast to the sand jungle, which is covered by sand dunes in the southeast, known as the sand dune.


Gohar Lake


Gohar Lake, known as Negin Zagros, is a mountainous lake in Iran that is located at the height of the Strankuh Mountain in Lorestan province, at a height of 2 meters above sea level.


This lake is located in the protected area of ​​Strankuh Duhrod, which is known as "Negin Strankhuh" because of the lack of access to the car, and to a great extent, it has been devastated by human pollution. About 4.1% of tourists visit the area annually.


Gohar is most likely caused by a large earthquake. The lake is located on the main fault of present-day Zagros. Therefore, it probably formed due to fault movement and the event of a landslide.


Gohar consists of two parts, namely the Great Gohar (Kalah Gohar) and the Small Gohar (Gohar Butter). The Great Gohar Lake is about 2 meters long and 4-5 meters wide and 4-5 meters deep.

The lake can be reached by car through the town of Dorood, which is the closest access to the lake. Recent rifts have made the lake easy to access.


The shore of this lake except for the western part of the lake (west side) and its opposite (eastern side) has a sandy beach and is suitable for swimming. At the bottom of the lake, there is a dense forest that is about to disappear.


Above it there is also a rainforest that is in danger of being destroyed. Above, the blue atmosphere flows into the lake, which continues to another lake. It takes about 2 minutes to reach this lake (second ghee or lower ghee).


Its depth is low and the fish on the lake floor can be seen with some care. The inlet flow of the lake water is 2 cubic feet per second and its outlet flow is about 2 cubic feet per second. The reason for the increase in the volume of water output of the lake is the presence of springs in the lower part of the lake.
