Nestled in the heart of southwest China’s Sichuan Province, Long Lake (or ‘Changhai’) is more than just a body of water—it’s a natural masterpiece. Known as the ‘blue elongated mirror’ for its crystal-clear, turquoise hues, this high-altitude gem in Jiuzhaigou Valley has captivated travelers and scientists alike. 🏔️
Why Long Lake Stands Out
At over 3,100 meters above sea level, Long Lake is the highest and longest lake in Jiuzhaigou. Fed by melting snow from the Min Mountains’ eternal peaks, its waters never overflow or dry up—earning it the Tibetan nickname ‘the treasure gourd’. Locals say its serene surface reflects the sky like a polished sapphire. 💎
A Geological Wonder
The lake’s unique structure, shaped by ancient glaciers and limestone deposits, creates its mesmerizing color. Scientists credit its clarity to mineral-rich runoff and a lack of human disturbance. It’s also the source of Jiuzhaigou’s entire water system, feeding iconic spots like Five-Flower Lake and Pearl Shoal.
For Travelers & Culture Lovers
Hiking trails around Long Lake offer Instagram-worthy views of snow-capped mountains and dense forests. 🌲 Pro tip: Visit in autumn when golden leaves contrast with the lake’s blue—a vibe straight out of a fantasy film! 🎬
