The best time to visit Jingning County, Gansu, China, is during spring (April to May) and autumn (September to October).
During these months, the weather is pleasantly mild, making it ideal for exploring the county's natural beauty and cultural sites. Spring brings blooming landscapes, particularly noticeable around the Dadiwan Site, one of China's earliest Neolithic settlements, where the surrounding area becomes lush and green. This period is excellent for those interested in history and archaeology, as the comfortable temperatures allow for extended outdoor exploration of the site's extensive grounds without the heat of summer.
Autumn offers equally agreeable weather with clear skies and comfortable temperatures, superb for outdoor activities. The scenic areas around the Kongtong Mountains, though a short drive from the county centre, are particularly stunning with their autumnal colours. This season is well-suited for travellers who appreciate photography and hiking, as the crisp air and colourful foliage provide a beautiful backdrop for sightseeing and walks.
