Red River Dyke and Long Biên Bridge Walk

The Long Biên Bridge is a steel bridge completed in 1902 that spans the Red River between Hoàn Kiếm and Long Biên Districts in Hà Nội, Vietnam. The walk starts at the west access near the Phùng Hưng and Yên Phụ area and is about 10 minutes on foot or by Grab from the Old Quarter. No permit or entrance fee is required, and the bridge is free to walk. Parking is limited near the access, so most visitors arrive on foot or by ride-hailing.

The route is about 5 km return along the dyke road and the historic bridge deck and takes 1.5 to 2.5 hours. It is flat apart from the ramps up onto the dyke and bridge, so the difficulty is easy. The surface is a mix of concrete, worn asphalt and steel-deck sections, some of it uneven. Exposure to sun is high, as there is little shade on the bridge and dyke, and trains and motorbikes share the deck, so walkers must keep to the pedestrian edge and watch for traffic.

Key landmarks are the bridge's iron latticework, the riverside farmland and sandbanks, ferries and the city skyline seen from the dyke. The walk is best at sunrise, when light is soft, temperatures are cooler and traffic is lighter. Walkers can turn back at the far bank or continue along the dyke on the Long Biên side, and there is no fixed turn-around point. A short bridge-only walk is an option for those with less time.

Water and food are available from small stalls near the Old Quarter end, though supplies on the dyke are limited, so a bottle is sensible. There is little shelter on the bridge, so rain and heat are best avoided. A face mask helps against dust and traffic fumes, and a hat and camera are useful. The cool season is the most comfortable, and sunrise offers the best conditions all year.
