When you're feeling down, come here for a walk: Huanglongtan in Heqing, Yunnan, China.

Huanglongtan is hidden in a high mountain canyon in Yunnan, China, with a mirror like turquoise water pool formed by limestone springs that is dazzling. Emerald like seawater winds through golden grasslands, surrounded by jagged peaks and ancient pine forests. Witnessing flocks of migratory birds dancing on the reflection of traditional Bai villages - this is a peaceful paradise where the earth is painted with the most exquisite watercolor.
