This is not Iceland, nor Xinjiang, this is Namtso in Tibet

Namtso, located in the central part of the Tibet Autonomous Region, is the second largest lake in Tibet and the third largest saltwater lake in China. - "Namtso" is Tibetan, and the Mongolian name is "Tengger Sea", both meaning "heavenly lake". Namtso is one of the "three major sacred lakes" in Tibet. Namtso is the first sacred lake of the ancient Bon religion in Tibet, and one of the famous Buddhist holy places. - 📍Detailed address: Tibet Autonomous Region-Lhasa City-Dangxiong County-109 National Highway - 🕙Business hours: 8:00-21:00 - ⏰Best travel time July to September is the best season for Namtso. However, due to the heavy rain during this season, the road conditions are very poor. - Accommodation🛏️ Many travelers will spend a night on the lake together, where they can see the Namtso in the early morning and dusk. There are earth houses for accommodation, which can accommodate up to nine people; you can also stay at the local garrison station and the earth enclosure where Tibetans live. Some travelers wish to walk to Namtso. Due to the high altitude, it will be very hard, and you need to bring enough supplies and equipment such as tents and sleeping bags. Tashi Peninsula has no electricity. There are a few houses for accommodation, but there is no running water. When it just gets dark at night, there may be electricity for a while. All the rooms together can accommodate up to forty people. If you can't rent a room, you can only set up a tent in the open air. It is best to arrive at Tashi Peninsula early during the peak travel season and rent a room as soon as possible. - Food🍛 The authentic Tibetan yogurt, which has long been rumored to be delicious, is a truly authentic Tibetan meal. Namtso is a saltwater lake, but the water is not particularly salty, and it can be drunk after boiling or filtering. - 📝Note tips: ✔️To go around the lake, it is about 280 kilometers along the lakeshore and about 320 kilometers along the simple highway. The whole journey is on foot, depending on physical conditions, 7 to 10 days. ✔️Driving around the lake requires a high off-road performance of the vehicle. There are many roads along the lake. You need to be led by someone who is familiar with the local road conditions. It takes 1 to 2 days. ✔️If you walk around the lake, you must first adapt to the plateau in Lhasa, because Namtso is nearly 5000 meters above sea level. You must be fully prepared for outdoor equipment, especially for rain protection. If you are physically fit, it takes about 8-10 days to go around the lake. If you are not physically fit, you need to be prepared to walk for about 15 days. ✔️Namtso is a saltwater lake, and the supply along the way is very poor, including water and other supplies, which need to be fully prepared. The yaks and horses carrying things need to be booked in advance in Bangor County. ✔️Route: Depart from Lhasa to Namtso Tashi Peninsula and stay, then turn Tashi Island and Yao Wang Mountain (Tashi Island must be turned in odd numbers, the custom of Tibetans is to turn Tashi Island 13 times, and then turn your own age on Yao Wang Mountain, how old you are, how many times you turn, the direction is clockwise). At Dong Tashi Bathing Gate, you can wash your face, throw treasures to Namtso, and offer Hada.
