Lake Goygol, often hailed as a gem of Azerbaijan, is a pristine, mountainous lake formed as a result of an earthquake in 1139 that triggered a massive landslide, subsequently damming the Kurmuk River. It is situated around 1,500 meters above sea level, on the foothills of the Lesser Caucasus Mountains near Ganja, Azerbaijan's second-largest city. Known for its crystal-clear waters that shift in hue through various shades of blue and green depending on the sunlight, the lake is a part of the Goygol National Park, an area renowned for its diverse flora and fauna. Surrounded by dense forests and a tranquil atmosphere, the lake area presents an excellent opportunity for hiking, picnicking, and appreciating the natural beauty. Accessibility to the lake itself is controlled to maintain its untouched condition and safeguard its ecosystem. The region has historical significance with various legends attached to it and offers scenic views that are a photographer's delight. In addition, the lake contributes to the biodiversity of the region and acts as a critical habitat for various species.
