Deyg-e Rostam Hot Spring

Deyg-e Rostam Hot Spring is one of the most remarkable natural and geological attractions in Tabas County, South Khorasan Province. It lies about 240 kilometers south of Tabas, beyond the historic village of Nayband, on the road from Dehuk to Ravar. This mineral spring is registered as number 326 on Iran's National Natural Heritage list. It sits amid the dry desert landscapes of the region, and the striking contrast between the boiling water and the barren surroundings creates a truly unique scene. The green-colored water, the steam rising from the spring and the constant sound of water bubbling up through volcanic rocks are among the first things that catch every visitor's attention. The name "Deyg-e Rostam" (Rostam's Cauldron) comes from this bubbling sound of the water among the rocky hollows.

Deyg-e Rostam is a valuable geological phenomenon of hydrothermal origin, and its water is rich in sulfur compounds, calcium, magnesium and other minerals. The water temperature at the spring's outlet varies between 57 and 76 degrees Celsius, so direct contact with the water at the source can cause burns. After flowing about 200 meters, the water loses part of its heat and enters a pool where tourists can bathe and enjoy hydrotherapy. Since long ago, locals and travelers have used this hot spring to ease rheumatic and joint pain, to help with some skin conditions and to relieve muscle fatigue. Around the spring there is also an expanse of basaltic volcanic rock, the result of tectonic activity and movement of the Nayband Fault in the distant past, which adds to the scientific value of the area.

To reach Deyg-e Rostam Hot Spring, drive from the city of Tabas toward Dehuk, pass the historic village of Nayband, and continue about 10 kilometers along the road to Ravar until you reach the spring. The hot spring area offers facilities for tourists, including gazebos, restrooms, a restaurant, shops and rest areas. The best time to visit is autumn, winter and early spring, when the desert air is milder and the hot spring is more enjoyable. Because the water at the source is extremely hot, do not enter the main spring; use only the safe pools. Please keep the area clean and protect its natural resources to help preserve this precious desert heritage.
