Located in Cu Chi Ward, ~70 km from Ho Chi Minh City’s Ward 1, the Cu Chi Tunnels are a 250-km underground network, hand-dug from 1946 to 1968 across Cu Chi and Hoc Mon wards. Set in a tropical monsoon climate—dry season (December–April, 25–35°C or 77–95°F) and rainy season (May–November, 23–32°C or 73.4–89.6°F)—the tunnels feature Ben Dinh and Ben Duoc sites, open daily from 7:00 AM to 5:00 PM. Designed for Viet Cong guerrilla operations, the three-level system, at depths of 3–12 m, includes narrow passages, hidden entrances, and facilities like Hoang Cam kitchens and hospitals. Restored as a national monument, the tunnels offer crawlable sections and exhibits, accessible via bus or guided tours, near the Saigon River.

The Cu Chi Tunnels were hand-dug over two decades (1946–1968) by Viet Minh and Viet Cong fighters using bamboo tools and manual labor, often under cover of night to evade detection. Construction involved:

• Teams and Techniques: Groups of 5–10 villagers, including men and women, dug tunnels and dispersed soil in rivers or fields to conceal activity. Women often camouflaged soil piles or planted vegetation over entrances.

• Camouflage Strategies: Entrances, as small as 30x40 cm, were hidden under termite mounds, roots, or leaves. Ventilation shafts used bamboo pipes disguised as stumps, with pepper sprinkled to deter U.S. sniffer dogs.

• Resourcefulness: Soil was stabilized with compacted earth, not reinforced materials, to maintain flexibility. Tunnels followed natural terrain, curving to disrupt enemy probing or gas attacks.

• Community Effort: Entire villages contributed, with children acting as lookouts and elders providing food, sustaining construction despite bombings.

This labor-intensive process created a resilient network, recognized as a national monument in 1979 (Ben Duoc) and 2004 (Ben Dinh), showcasing Vietnam’s architectural ingenuity.

Well, 15m deep, clear. The tunnel system consists of 3 floors, from the "backbone" line radiates long branches, short branches link through each other, branching out to the Saigon River. The floor is 3m above the ground, resistant to artillery shells and weight of tanks, armoured vehicles. Level 2 is 5 meters away from the ground, can resist small bombs. The last floor is 8-10m from the ground very safe. The way up and down between the basements is arranged with secret tunnels. The tunnel with broad tunnels for rest, a place to store weapons, food, wells, Hoang Cam stove, commanding tunnel ... There are also large tunnels, roofs cool, camouflage ingenious to watch movies, arts.

The Cu Chi Tunnels’ architecture remains a testament to wartime engineering, with restored sections at Ben Dinh and Ben Duoc revealing its sophisticated design:

• Three-Level Structure:

  • Level 1 (3–4 m deep): Resistant to artillery, used for quick access and combat, with multiple trapdoors.

  • Level 2 (5–6 m deep): Housing meeting rooms, kitchens, and hospitals, fortified against small bombs.

  • Level 3 (8–12 m deep): Safest level for command centers and storage, with connections to the Saigon River for escape.

• Narrow Passages: Tunnels are 0.5–1 m wide and 0.8–1.2 m high, designed for agility and defense, with zigzags to block blasts.

• Ventilation Systems: Bamboo pipes, hidden as stumps, provided air, angled to prevent flooding.

• Hoang Cam Kitchens: Smokeless stoves dispersed smoke through multi-tiered vents, concealing cooking activity.

• Facilities: Included wells, storage rooms, medical bays, and theaters, with cool, camouflaged roofs for cultural events.
