Located in the Lankaran-Astara Lowland and the Talysh Mountains, Hirkan National Park spans a combination of humid subtropical lowlands and cool mountainous zones.
Key geographical characteristics:
• Altitude range: from near sea level up to approximately 2,200 meters
• Climate: warm, humid subtropical climate with high rainfall
• Rainfall: among the highest in Azerbaijan (up to 1,800–2,200 mm annually)
• Forests: evergreen and mixed deciduous Hyrcanian broadleaf forests
• Hydrology: numerous small rivers, mountain springs, forest streams, and seasonal waterfalls
• Soil: rich alluvial and brown forest soils supporting dense vegetation
Major rivers flowing through or near the park include the Tengerud, Velvele, Istisu, and Astarachay, which contribute to the overall ecological richness of the region. High humidity maintains thick undergrowth, moss-covered tree trunks, and a unique microclimate supporting diverse flora.
