There is a Metasequoia forest in downtown Beijing that is as beautiful as the botanical garden.

I regret not knowing it earlier. There is a large Metasequoia forest on the shore of Ark Lake in Chaoyang Park. The leaves turn red in mid-November. It is a great place to take photos in both sunny and rainy days. The leaves will fall by the end of the month. 📍｜Navigate to Ark Lake Pier. Take Metro Line 14 to Zaoying Station, and enter Chaoyang Park from West Gate 3.
