Golestan National Park, also known as the Golestan Jungle, is an Iranian national park in northeastern Iran. It is situated in the eastern part of the Alborz Mountains and the western edge of the Kopet Dag Mountains. It covers an area of 91,890 ha. Geographically, the park is nestled in a unique location, where the humid Caspian climate meets the dry climate of the Iranian plateau. This convergence of climates has resulted in a diverse range of flora and fauna, making Golestan National Park a haven for biodiversity. The park's terrain is characterized by rolling hills, steep slopes, and mountain peaks, with elevations ranging from 370 to 2,400 meters above sea level. The park's vegetation is equally impressive, with a mix of deciduous and coniferous forests, including beech, oak, and hornbeam trees. The forests are interspersed with grasslands, scrublands, and rocky outcrops, providing a habitat for a wide range of wildlife. Some of the notable species found in the park include the Persian Leopard, Brown Bear, Indian Wolf, Wild Boar, Golden Jackal, Caspian Red Deer, Roe Deer, Wild Goat and Goitered Gazelle. Golestan National Park is also home to a variety of bird species, including the Imperial Eagle, White-Tailed Eagle, and Peregrine Falcon. The park's wetlands, including the Golestan River and its tributaries, provide a habitat for fish and amphibians, such as the Caucasian Frog and the Iranian Cave Barb. Today, Golestan National Park is a popular destination for eco-tourists, scientists, and nature enthusiasts, offering a range of activities, including hiking, camping, and wildlife watching.
