After lunch in Jiuzhaigou Scenic Area, we took a sightseeing bus at the Nuoerlang Tourist Service Center to start visiting the left side of Jiuzhaigou'Y' shape. The final point is Changhai. This is the highest altitude attraction in Jiuzhaigou and the largest sea. Highlights: The lake is like a mirror, the water and the sky are the same color, the best time to visit and use reference: afternoon, 30 minutes. Changhai, located at the end of Zechawagou, the peak next to Changhai is snowy all year round, surrounded by forests, standing on the Changhai Observation Deck, blue sky and white clouds, the peak snow has a panoramic view, feeling that the mountains and the sky are connected together, there is no distance, this is also a large landscape of Changhai. Walk down the boardwalk next to the observation deck and come to the pool of green jade. Close to the long sea, I feel that the lake is as wide as the sea, the lake is as green as jade, the green mountains towering into the clouds, the clouds are like illusion... When visiting the long sea, you need to pay attention to a round cypress on the coast, which has a strange shape, one side of the branches and leaves are horizontal, and the other side is bald like a knife. It is called a single-armed old cypress. There are signs. The sea is like a clear mirror. The typical glacier landscape such as the ice bucket and the "U" valley are in sight. The trees on the shore are lush, the peaks are bathed in the blue sky and white clouds, and the scenery of Changhai is beautiful from the heart. Here you can arrange more time to stop and enjoy.
