For a dose of history and impressive views, take a walk or cycle across the iconic Long Bien Bridge. Designed by Gustave Eiffel (of Eiffel Tower fame) and completed in 1902, this cantilever bridge spanning the Red River was a marvel of engineering for its time and played a crucial strategic role during Vietnam's wars, surviving numerous bombing raids.

While heavily used by trains, motorbikes, and pedestrians, walking along the designated pathways offers fantastic views of the river, surrounding farmland, and the city skyline. The bridge's rustic, weathered appearance tells tales of its long history, making it a popular spot for photographers and those seeking a connection to Hanoi's past.
