Harbor cities are urban areas located near coastlines, where ships can dock and load or unload goods. These cities often develop around natural harbors, which provide safe anchorage for vessels. The presence of a harbor facilitates trade and commerce, making these cities vital economic hubs. Examples of harbor cities include San Francisco, Hong Kong, and Rotterdam. In addition to their economic significance, harbor cities often feature vibrant waterfronts that attract tourism and recreational activities. They may have marinas, parks, and cultural attractions along the coast. The combination of industry and leisure makes harbor cities unique and dynamic places to live and visit.
