From the Martian hills to the salt tunnel, that  attracts many tourists to visit this area these days, especially in the cold season. Garmsar region, that hosts the largest salt mines and tunnels in the Middle East, currently has 40 salt tunnels and a major share of salt extraction in our country takes place in this region. In many countries of the world, such as Italy, Germany, Poland, by creating special facilities, they take advantage of the positive effects of salt with the titles of energy therapy or salt therapy, and build artificial rooms and caves, thus contributing to the prosperity of tourism and medical tourism.

Salt Mines of Garmsar is one of the extraordinary salt mines in Iran, which is visited by many nature tours.

There are many salt domes in different parts of Iran, which are located as separate and separate sources and cause the destruction of natural resources. The main points of accumulation of salt domes are in Bandar Abbas, south of Kazerun, north of Kerman, north of Yazd and south of Semnan. Geological and quality studies of water resources in the Hablehrood region of Garmsar in the area of ​​Arous Iran and Prince Hossein have been conducted, which has examined the expansion of salt domes in this region.

Padeh is a village in the Aradan section of Garmsar city in Semnan province, and what distinguishes Padeh village from other tourist attractions in Semnan in this area is the existence of large salt tunnels. Kuhdasht mine is located in the southeast of Garmsar and in the east of Tehran. This mine is the place where the salt dome with gypsum and salt cover rises. Inside such salt domes is the place where oil is trapped (oil traps).

Salt has been extracted from the mines of this city for about ten years. One of these mines is in the shape of a mountain and the way salt is extracted from it has led to the formation of Dastan Cave. Usually, a special formwork is modeled for the construction of tunnels on roads, a form that guarantees the strength, durability and security of the tunnel, but for the opening of the cave and the formation of this cave, only the distance between the height and the width is considered. The height is approximately twice the width and is rectangular.

At the entrance to the cave, the walls are dark and gray, and the closer we get to the depths, the brighter and brighter they look. Approaching the brighter levels indicates that the time of digging that point of the cave is closer to the present. Walking along these tunnels, we see salt walls, all of which are hung by salt ice chandeliers that give these tunnels a beautiful look. Salt Mines of Garmsar

Martian hills and domes and salt tunnels are scattered over a relatively large area. There are about 27 salt mines near Garmsar; But these attractions are specifically located about 15 km west of Garmsar and 90 km from Tehran on the Ivanki and Garmsar roads. Passing Ivanki, a number of these hills and their views will be seen. Eighty-five percent of the salt extracted from this mine is consumed orally and sent to various places.

To visit Salt Mines of Garmsar, you must have a suitable swan light because the inside of the cave is dark and due to the heavy traffic in the middle of the path to the end of the cave is slippery and it will be safer to cross the sides.
