Hi everyone! I’m Steven from the UK. I travel around the world, looking for our planet’s most beautiful places. That’s why I’m here in Xizang, China. Right now, I’m standing in front of the world - famous Namtso Lake. It took about four hours to drive here from Lhasa, the capital city of Xizang.
So, what makes Namtso Lake so special? It’s over 4,700 metres above sea level. That makes it the highest saltwater lake in the world. No wonder the name Namtso means “sky lake” in the local language. Up here, I feel like I could reach up and touch the clouds!
There’s more to this lake than its height. The lake is a natural wonder. The water is clear and blue. And look at the snowy mountains in the distance! How beautiful! Because this lake is so high in the mountains, it’s a little cold right now, even though it’s summer. The wind can get very strong at this lake too. You can really feel the power of nature here.
Tonight, I’m going to stay at a hotel nearby because I want to watch the sunset over the lake. At sunrise and sunset, the sky and the water turn red and golden. If you ask me, there’s no better time to see the beauty of this amazing lake.
