Heilongtan Park is near the ancient town of Lijiang. It is about ten minutes from the back of the waterwheel of the ancient town of Lijiang. At the end of the park is Heilongtan Park, which is open to tourists free of charge. Speaking of Black Dragon Pool Park, the most well-known is the reflection of Yulong Mountain in the pool water. The park is located at the foot of the North Elephant Hill of the ancient city. There is a moon tower and five-hole Bridge in the center of the clear spring pool. Because the five-hole Bridge is being repaired on the same day, we can only see the moon tower in the pool from afar. Heilongtan is also the water source of the ancient city of Lijiang. Many tourists, including foreigners, enter the Black Dragon Pool Park to photograph the reflection of Yulong Snow Mountain. The best time to shoot Yulong Snow Mountain is in the morning and evening. If the weather is clear, the snow mountain is reflected in the pool, with blue sky and white clouds, which is very beautiful. If you come here during the rainy season in June and July, it will be very difficult to take a picture of the reflection. In addition to photographing the reflection of Yulong Snow Mountain, the plants in the park are also worth watching. In May, the whole road in Heilongtan Park is full of cherry trees, cherry blossoms are in full bloom, and you can also enjoy the beautiful scenery of cherry blossoms without going to Korea.
