About this place
Tanjungbalai is a city in North Sumatra where the Asahan River meets the sea, nicknamed Clam City for its historic shellfish production. It sits about 140 km south of Medan and feels more like a working river port than a polished resort town — that is part of its honest charm.
The city is best used as a base for exploring the estuary and nearby villages. The annual Pesta Kerang (Clam Festival) at the end of the year is the main draw, celebrating the city's heritage and birthday with local food and festivities.

Planning Tips
