About this tour
When Lily from our BugBitten team ran this half-day private tour, we descended into Ben Duoc—a sprawling network of tunnels that sheltered Viet Cong fighters during the Vietnam War. The 250km-plus tunnel system, dug by hand, reveals kitchens, hospitals, command centres, and booby traps that once defined underground warfare. Before crawling through tight passages, we stopped at local rubber plantations or rice fields to get a feel for the rural landscape above. It's a sobering, tangible look at guerrilla tactics and the scale of what soldiers endured. Six hours total, finishing back at your hotel by early afternoon.
Highlights
- Crawl through original tunnel sections with period details intact
- See functioning kitchen areas, hospital spaces, weapons caches underground
- Stop at working plantations or fields before descending
- Tight, claustrophobic passages give real sense of confined life
- Private car and guide means no rushing through crowds
- Honest take on the engineering and human cost of war
- Mix of walking and genuine crawling—not a polished museum walk
- Finish by early afternoon, leaving rest of day free
What to expect
Lily's day started with a pick-up in a comfortable air-con car. The driver navigated to the site via local plantations or rice paddies—useful context for what the landscape looked like when tunnels were being dug. Once at Ben Duoc, our guide walked us through the layout and history before we actually entered the tunnels themselves.
Then came the crawling. Some sections are walkable—low ceilings, narrow paths—but others require you on hands and knees through tight gaps. It's deliberately uncomfortable, which is the point: you get a visceral feel for what fighters lived with daily. The temperature drops, light fades, and the claustrophobia is real. You'll see crude living quarters, trap doors, and sections that show how ingeniously people worked underground. By contrast, the scale of the system—over 250km—is staggering when you realise it was hand-dug. The tour wraps by early afternoon, so you're back at your hotel with time to decompress and process.

Good to know
This is a private tour, so you're not shuffled through with 40 others. Your guide can pace things to your fitness and comfort. Ben Duoc is historically significant and sobering—not a theme-park version of history. You walk and crawl through actual tunnels, not reconstructions. If you want to understand Vietnamese resilience and the reality of guerrilla warfare, it lands hard.
The crawling is genuinely tight and claustrophobic. If you have back or spine issues, skip this. Even fit people might feel uncomfortable in narrow sections. The tunnels are humid and can be disorienting. You'll be dirty after—wear clothes you don't mind staining. Meals aren't included, so budget for lunch before or after. The site is educational rather than comfortable; expect silence and reflection, not thrills. Early finishes mean you need to be ready to go at the scheduled pick-up time.
Wear closed shoes with grip, long trousers (scraped knees are common), and a torch if you have one. Bring water. The six-hour slot includes travel time, so expect 3–4 hours on-site. Best in dry season; wet season makes tunnels muddy and slippery. Solo travellers, couples, and small groups all work. Peak times are mornings; mid-week is quieter.
