Kio Lake

Kio Lake (in Luri: Sarav Kiyav) is one of the most beautiful natural attractions of Khorramabad, in Lorestan Province. It covers an area of about 7 hectares in the northwest of the city. Because it lies within the urban area, this natural lake is one of the few lakes in Iran located inside a city. Its water is supplied by natural springs such as the Golestan Spring, and its depth ranges from 3 to 7 metres, which makes it suitable for boating and other water recreation.

In the Luri language, the name "Kio" means "deep blue", a reference to the distinctive, appealing colour of the lake's water, which together with the lush surroundings creates a captivating view. The lake is home to various species of birds and aquatic life, so it is a popular destination for nature lovers and photographers alike. Around the lake there are facilities such as an amusement park, pleasant walking paths and recreational areas, which have made it one of the most popular tourist spots in Khorramabad. The lake is also close to other attractions such as Falak-ol-Aflak Castle, the traditional bazaar and the Shapuri Bridge, so visitors can explore the region's culture and history in full.

The best time to visit Kio Lake is spring, especially the months of Farvardin and Ordibehesht (roughly late March to late May). During this period the weather in Khorramabad is mild and pleasant, and the nature around the lake is at its freshest and greenest. Thanks to the winter rainfall, the water level of the lake is also at its highest, which adds to its beauty. Autumn, with its cool weather and colourful scenery, is also a good time to visit. In summer, however, the heat, especially during the day, may be uncomfortable for some visitors. In winter, the lake is less appealing because of the lower temperatures and the lull in activity in the recreational areas around it.
