Aghgol National Park, Wetland national park in Mil plain, Azerbaijan

Aghgol National Park is a wetland area in the Mil plain of southeastern Azerbaijan, built around a network of connected lakes, marshes, and reed beds. The landscape shifts noticeably between seasons, alternating between open water, dense reed zones, and dry grassland.

The area was already a protected state reserve during the Soviet era before being upgraded to a national park in 2003 to strengthen habitat protection. The change came in response to growing pressure on the wetlands from farming and water extraction in the surrounding plains.

The name Aghgol means "White Lake" in Azerbaijani, likely because the shallow, highly saline wetland dries out in summer, exposing a salt layer that looks white from afar. According to older residents, locals once extracted table salt here in summer. The lake is mostly surrounded by reeds, which cover more than 2,000 hectares.

The park is open throughout the year, but spring and autumn draw the most wildlife activity, making those seasons the best time to visit. Solid footwear is a good idea since trails pass through wet ground and open grassland.

Although the terrain looks flat and unremarkable from a distance, the park sits along one of the key migration corridors between Europe and Central Asia. Over 140 bird species have been recorded here, including white-tailed eagles and spoonbills that stop over during long-distance flights.
