Located between the Chenggong Bridge and MacArthur Bridge No. 1 over the Keelung River, the Chengmei Left Bank Riverside Park occupies an area of about 22,000m2. The Chengmei Left Bank Riverside Park and Chengmei Right Bank Riverside Park on the opposite bank can be said to be a water corridor connected by lights. After nightfall, the lights and hydrology are reflected in one breath, sparkling and moving. The HEO grows flower seas in the park in a large area in different seasons to surprise citizens passing by. Thanks to the remediation success of the Keelung River, ichthyo-diversity has increased. Visiting the park in the evening, you will see swarms of fish jump out of the water. Entering the city from Floodgate 4 (Raohe Evacuation Gate) next to the Rainbow Bridge, you can reach the famous Raohe Street Night Market of Taipei, where there is food and fun. Ciyou Temple at the end of Raohe Street has many worshippers. It is also another should-visit attraction after visiting the Chengmei Left Bank Riverside Park.
