So beautiful! I recommend Tai Shi Tun He Yuan Park in Miyun.

Tai Shi Tun He Yuan Park in Miyun Pros: No entrance fee, free parking, pet-friendly, swans, suitable for all ages Cons: The park is small, but you can visit Miyun Reservoir or Qing Shui River as well Just search for Tai Shi Tun He Yuan Ecological Park on Baidu Maps. The park is long and narrow, not very big. But the scenery is really great. Although the temperature dropped on the weekend, the blue sky was a bonus. And surprisingly, although it was late autumn, many trees still had leaves, which made the scenery more layered. The most surprising thing is the swans. According to the locals, many swans fly here to spend the winter every year. I saw about 15 swans that day. But they were too far from the shore, and my phone was blurry even with 15x zoom. _(: 3 」∠)_ I should have used professional equipment, haha. According to photography enthusiasts, the swans here are more active and fly before 8 am. So if you want to take photos or see swans, you should stay nearby. And the scenery of Qing Shui River or Miyun Reservoir is really great recently. It would be better to stay for a day to experience it. Besides, it is really cold by the water. Bring an extra piece of clothing when you go out recently, and be careful not to catch a cold.
