Ningbo Drum Tower, located in the center of Ningbo, is one of the landmark buildings in Ningbo. The Old Bund is also a famous scenic spot in Ningbo, located in the east of Ningbo, not far from the Drum Tower.
According to the map and navigation system, the straight-line distance from Ningbo Gulou to the old Bund is about 2 kilometers. If you are going to walk, it will take about 20-30 minutes. Of course, the specific time will also be affected by traffic conditions and personal walking speed.
