The Dena Protected Area, spanning 93,660 hectares across the Kohgiluyeh and Boyer-Ahmad and Isfahan provinces, stands as a testament to Iran’s biological richness. Established in 1990 to preserve its intact nature, this mountainous sanctuary is a land of permanent glaciers, high-flow rivers, and dramatic altitude shifts ranging from 1,360 to 4,413 meters.

Climate and Geography

Dena’s unique geography creates a diverse climatic profile. With a mean annual precipitation of 650 mm and an average temperature of 14°C, the region experiences cold sub-humid to humid climates. Visitors should prepare for:
