Emerald Lake, or Dachaidan Emerald Lake, is a captivating natural wonder in Qinghai, China, formed from a former salt mining operation. Its unique geological composition has created a series of interconnected salt lakes, each displaying a spectrum of colors from emerald green and mint blue to milky white and amber yellow. This 'palette of the earth' effect, combined with the reflections of the sky and distant snow-capped mountains, makes it a truly picturesque destination, often considered more stunning than the more famous Chaka Salt Lake by many visitors.
Visitors consistently rave about the lake's incredible, almost surreal beauty, noting that the vibrant colors are even more impressive in person than in photos. Many highlight the opportunity for stunning photography, especially with a drone, which reveals the intricate patterns and varied hues of the different lake sections. The observation tower at the end of the miniature train ride is frequently mentioned as a worthwhile stop for panoramic views. Some reviewers also suggest exploring beyond the main areas to discover smaller, even more vibrantly colored lakes. The staff are often commended for their helpfulness, with one notable instance of assisting a visitor whose drone fell into the lake.
To make the most of your visit, aim for a sunny day, as strong sunlight intensifies the lake's colors and enhances photographic opportunities. Early mornings are recommended to avoid crowds and experience the tranquil atmosphere. While a miniature train is available for transport within the scenic area, some visitors suggest skipping it and walking or driving to explore the different lake sections at your own pace, particularly the largest lake on the right upon entering. Consider paying an extra 20 yuan for access to a viewing platform if you don't have a drone. For those seeking exclusive views, off-road vehicle tours to more remote, vibrant lake areas are available, though they come at a higher cost (around 700 yuan per car).
A common complaint is that the scenery can be less impressive on cloudy days, making photos less vibrant. To mitigate this, check the weather forecast and plan your visit for a clear, sunny day. Some older reviews mention the area being free and less developed, but it is now a mature scenic spot with an entrance fee and organized facilities, including the train. While the train can be noisy, it offers a convenient way to cover distances for those with limited mobility. Be aware that during peak season, the area can get very crowded, especially around popular photo spots like the glass boat experience.
