Siah Kuh (Persian: سیاه کوه), meaning “Black Mountain,” refers to several locations in Iran, but the most prominent is the Siah Kuh National Park. Located on the border of Yazd and Isfahan provinces, it is celebrated as one of the most untouched and remote ecotourism destinations in Central Iran.

Geography and Location

Spanning approximately 80,786 hectares, the park’s landscape is a dramatic contrast of rugged mountain ranges and sweeping sandy plains. Its extreme isolation from residential areas has preserved its status as a “biological island,” offering a level of pristine wilderness rarely found elsewhere in the region.

Biodiversity and Rare Wildlife

Siah Kuh is a critical sanctuary for some of the rarest desert-dwelling species in the Middle East:

• Mammals: The park serves as a vital habitat for the critically endangered Asiatic Cheetah. Other notable residents include the caracal, Striped Hyena, Wild Goat, Wild Sheep (Ovis orientalis), and the Chinkara (Indian Gazelle).

• Avifauna: Birdwatchers can spot the Houbara bustard, various species of Partridge, and high-altitude Falcons.

Climate and Environment

The region is characterized by an arid and subtropical climate.

• Temperature: The average annual temperature is 19°C, though summer extremes can be much higher.

• Rainfall: Water is scarce, with an average annual precipitation of only 65mm, creating a fragile but resilient ecosystem.

Best Time to Visit

The optimal window for exploration is from late March to late May. During this spring period, the weather is most temperate, and the biodiversity is most active, making it the ideal time for wildlife photography and trekking.

Accessibility

Due to its protected status, access is strictly regulated. Entry is primarily facilitated through the Siah Kuh Protected Area via the Ardakan-Chopan Road.

Note: Visitors are advised to coordinate with the local Department of Environment, as special permits and authorized guides are often required to enter the core national park zones.
