An extensive underground network stretching over 200 kilometers (approx. 120 miles), these tunnels served as living quarters, supply routes, and hiding spots for Vietnamese soldiers during the Vietnam War. Today, visitors can explore sections of the tunnel, learn about wartime life, and see the ingenious traps used during the conflict. For a small fee, you can also use the firing range, shooting live rounds from guns used in the war.

Hanoi Old Quarter Vietnam is a bustling network of narrow streets, hidden alleyways, and historic shophouses where traditional trade, street food, and modern city life all blend together. From the legendary 36 guild streets to Hoan Kiem Lake, Ngoc Son Temple, and St. Joseph Cathedral, this atmospheric neighborhood offers a deep, authentic glimpse into the soul of Hanoi.
