Chaka Salt Lake

China's "Mirror of the Sky": a white salt lake reflecting blue sky and clouds, with a little train rolling out to the middle of the lake, and a classic stop on the Qinghai–Gansu Grand Loop.

Chaka Salt Lake is in Chaka town, Ulan County, Haixi Mongol and Tibetan Autonomous Prefecture, Qinghai Province. It lies in a mountain basin between the Qinghai Nanshan and the E'la Mountains on the eastern edge of the Qaidam Basin, at about 3,059 m, with a lake surface of about 105 square kilometres. It is a natural crystalline salt lake that has been mined for more than 3,000 years. The lake is covered all year with a thin layer of brine, and on windless clear days it mirrors the blue sky, white clouds and distant snowy mountains, earning the name China's "Mirror of the Sky" and making it one of the most popular photo stops on the Qinghai–Gansu Grand Loop. There are two main areas: the main scenic area on the north shore, Chaka Salt Lake · Mirror of the Sky (salt sculptures, the salt lake museum, an observation tower and the little train, where the classic image of the railway running into the lake is taken), and Chaka TianKongYiHao (Sky No. 1) in the eastern section, which has fewer people and reflections that are easier to photograph. Chaka town lies just north of the lake and is the place to stay overnight and eat Chaka lamb. The climate is high-altitude continental. The best season is June–September, with daytime highs of about 15–25°C and just a few degrees in the early morning and evening. The lake is calmest on windless mornings and before sunset; at midday the wind is stronger and reflections break up. In winter, ice and salt flowers intermingle on the lake, with very few visitors and bitter cold. Getting there: from Xining it is about 300 km and 4 hours via the Beijing–Tibet Expressway; from Heima River at Qinghai Lake to Chaka is about 1.5 hours (over the 3,817 m Xiangpi Mountain Pass); Chaka railway station has trains toward Xining and Golmud; heading west via Ulan County (Hala Hatu Forest Park, Jinzi Sea) you can reach Delingha and Da Qaidam. We suggest half a day to 1 day, ideally staying in Chaka town to enter the lake when the park opens in the morning and catch the sunset again in the evening. Notes: UV at altitude is very strong, so sunscreen, sunglasses and a hat are essential; brine irritates wounds and skin, so rent rain boots or wear shoe covers in the lake and rinse with fresh water afterward; there are caves under the salt crust, so do not leave the designated area; above 3,000 m, first-time visitors to the plateau should avoid strenuous activity; in peak season (July–August) accommodation in town is tight and should be booked in advance.
