Changhu Lake is located in Weize Village, Huzhen, 26 kilometers away from Shilin Scenic Area, surrounded by mountains, with an altitude of 1907 meters. The plane shape of the lake is like a slim girl, which is the hometown of Ashima in folklore. Because the lake is hidden in green mountains and green waters, and because there are few tourists in the past, it is called "hidden lake".

In the long lake, tourists can drift, fish or climb mountains. In the evening, you can rent tents, watch Yi people's song and dance performances and participate in the local Torch Festival. The best time to travel in Changhu Lake: Every year on June 24th of the lunar calendar, Shilin Scenic Area will hold a grand Yi Torch Festival Carnival. Friends who love lively and folk activities can come to Shilin to play at this time, which will definitely satisfy you.
