The Cu Chi Tunnels are a hand-dug network of underground passages in Cu Chi district, on the north-western edge of Ho Chi Minh City, that sheltered Viet Minh and later Viet Cong fighters through the wars against France and the United States. Historians put the full system at somewhere between 200 and 250 kilometres at its peak, with sleeping chambers, kitchens, field hospitals and command rooms stacked on three levels beneath the forest. Two sections are open to visitors today: Ben Dinh, which receives most tour groups, and Ben Duoc, farther out and quieter.
This guide is written for travellers planning a half-day or full-day trip from the city. It covers how the tunnels were built and used, the real differences between the two sites, what a visit looks like minute by minute, how to get there by road, river or public bus, what tickets cost as of October 2026, and who should skip the crawl. If you are building a wider trip around southern Vietnam, the tunnels pair well with a day in the city's museums and an evening on the river.

Cu Chi Tunnels history: why a village network became a war base
The tunnels began in the late 1940s as hiding places during the war against French rule, then grew dramatically in the 1960s. Cu Chi lay close to Saigon, the southern capital, and close to large American bases, which made it a staging ground for attacks on the city.
Local villagers and fighters dug with hoes and baskets, carrying the spoil away at night so fresh earth would not give the tunnels away. Passages connected hamlets, ran under rice fields and rubber plantations, and in places reached the banks of the Saigon River. The system was never one tunnel but a web of short segments joined by trapdoors and water traps, so that a breach in one section did not expose the rest.
US and South Vietnamese forces tried several times to clear the district. Operation Crimp in January 1966 used about 8,000 troops. Operation Cedar Falls, from 8 to 26 January 1967, used roughly 30,000 and combined bombing, defoliants and bulldozers that flattened the Iron Triangle forest above. Specially trained soldiers known as tunnel rats went down with a pistol and a torch to search the passages. Large parts of the network survived anyway, and fighters used the area to prepare for the 1968 Tet Offensive on Saigon.
The cost was enormous on every side. Life underground meant heat, foul air, mosquitoes, scorpions and malaria, and the district was one of the most heavily bombed places in the war. That human weight is what makes the visit more than an adventure attraction, and the better guides make it clear.
How the tunnels were built and how they worked
The tunnels survived because of the soil. Cu Chi sits on hard red laterite clay that holds its shape when dug and sets firm when dry, strong enough to carry the weight of armoured vehicles above.
Engineers worked to a few simple rules. Entrances were tiny, often a square trapdoor barely wider than a slim adult's shoulders, covered with a lid and leaf litter. Passages zigzagged so that a grenade or a burst of gunfire could not travel far. Levels were separated by water-filled U-bends that blocked gas. Air holes came up inside termite mounds or bamboo clumps.
The best-known innovation is the Hoang Cam kitchen, named after Hoang Cam, the Viet Minh army cook who devised it in the early 1950s. Smoke from cooking fires ran through a series of chambers and long channels before seeping out at ground level far from the kitchen, so spotter planes could not trace it. At Ben Dinh you can see a reconstruction and, at the end of most tours, taste steamed cassava dipped in crushed peanuts, sesame and salt, the staple food of the fighters.
The scale is easy to underestimate from the short visitor loops. The Cu Chi complex alone is usually given as around 120 km of passages, dug by hand with hoes and baskets, with the spoil scattered in rivers and bomb craters so that fresh earth would not give the work away.
Ben Dinh or Ben Duoc: which Cu Chi Tunnels site to visit
Choose Ben Dinh if you want the shortest drive and the most demonstrations; choose Ben Duoc if you want fewer people and a stronger memorial focus. Both are managed as historic sites and both let you go underground.
Ben Dinh tunnels: the classic half-day visit
Ben Dinh is where nearly every group tour stops, and the site is set up to show a lot in a short loop. A guide leads you along forest paths past camouflaged entrances, examples of bamboo and steel spike traps, a destroyed armoured vehicle, bomb craters and reconstructed meeting rooms and workshops where fighters turned unexploded bombs into mines.
The visitor tunnel sections have been widened and some are lit. You choose how far to crawl, and there are exit points along the way. Expect a short film at the start, recorded in the 1960s style of the period, which some visitors find one-sided; treat it as a historical document in its own right.
A firing range sits within earshot, where you can pay to fire old military rifles by the bullet. The sound of gunfire carries over the whole site, which unsettles some visitors and is worth knowing about if you travel with children.
Give Ben Dinh two to three hours on site, plus about 1.5 hours each way by road from District 1 in normal traffic. Crowds build from mid-morning on most days. It suits a first visit or a tight schedule.
Ben Duoc tunnels: quieter, with a memorial temple
Ben Duoc was part of the regional command base and feels less staged. The tunnel sections here are closer to their wartime size, so crawling is harder and the experience is more authentic for those who want it.
The site includes the Ben Duoc Memorial Temple, built to honour the people who died in the Cu Chi area, and an attached memorial area with names inscribed on stone. Many visitors find this the most moving part of the day.
Ben Duoc sits farther from the city, so add travel time. Fewer tours stop here, which means quieter paths and more freedom to linger. A private car is the easiest way to get here.
You need the same two to three hours here, but the drive from District 1 is closer to two hours. Crowds are light compared with Ben Dinh, which is why history readers and photographers tend to prefer it.
Ben Dinh vs Ben Duoc, head to head
| Ben Dinh | Ben Duoc | |
|---|---|---|
| Distance from the city | closer | farther, add about 30 minutes |
| Tunnel size | widened for visitors | closer to original size |
| Crowds | busy, many group tours | quieter |
| Highlights | traps, workshops, armoured vehicle, kitchen | memorial temple, command base |
| Firing range | yes, on site | check locally |
| Suits | first visit, short on time | second visit, history focus |
What a visit to the Cu Chi Tunnels looks like
Most visits follow the same sequence: a short orientation film, a guided forest walk past entrances and traps, one or more tunnel crawls, a stop at the kitchen for cassava and tea, and free time at the end.
Crawling through the visitor tunnels
The visitor sections run from a few dozen metres to around 100 metres, with exits along the way so you can come up early. Inside it is hot, humid and low; most adults move in a crouch or on hands and knees. Your clothes will pick up red dust. A phone torch helps, though some sections have lights.
Try the trapdoor entrance first. Guides lift a lid barely wider than an A4 sheet and invite visitors to lower themselves in with arms raised. It is a quick way to understand how small the fighters had to be and how hard the tunnels were to find.
The two sites offer a different crawl. At Ben Dinh some passages have been made wider and taller for visitors, so most adults can get through with a crouch. Ben Duoc preserves more of the original system and feels closer to the real conditions. If you are unsure, start with the shortest section and use the first exit; guides are used to people turning back.
The traps and the weapons workshop
Displays show swinging spike doors, pit traps with sharpened bamboo and folding traps designed to catch a leg. They are confronting to look at. The workshop area shows how fighters cut open unexploded bombs to reuse the explosive, a dangerous job that killed many of those who did it.
Read this before you crawl: The tunnels are dark, hot and tight even after widening. Skip the crawl if you have claustrophobia, heart or breathing problems, back or knee injuries, or are pregnant. You still see the entrances, traps and kitchen from the surface.
Carry water, use insect repellent, and keep children close near the trap displays and the firing range.
The trap displays are reconstructions, not original pieces, and guides usually explain them from the fighters' side of the war; the War Remnants Museum in the city adds the wider context.
How to get to the Cu Chi Tunnels from Ho Chi Minh City
A group tour or a private car is the easiest way; a speedboat on the Saigon River is the most scenic; the public bus is the cheapest and the slowest.
Ways to reach Cu Chi from District 1
| Option | Time each way | Good to know |
|---|---|---|
| Half-day group tour | about 1.5 to 2 hours | usually Ben Dinh; pick-up from District 1 hotels; morning and afternoon departures |
| Private car with driver | about 1.5 to 2 hours | choose your site and timing; easiest way to reach Ben Duoc |
| Speedboat on the Saigon River | about 1 hour on the river | more expensive, cooler and far more scenic; half-day boat tours run about 5 to 6 hours in total |
| Public bus | 2.5 hours or more | change buses in Cu Chi town; only for patient travellers on a tight budget |
| Ride-hailing car (Grab) | about 1.5 to 2 hours | agree a return plan in advance; few cars wait at the site |
Many full-day tours combine the tunnels with the Cao Dai Holy See in Tay Ninh province. It makes a long day in a vehicle, so decide whether you want depth at the tunnels or breadth across two sites. Book Vietnam tours that state clearly which tunnel site they visit, because “Cu Chi Tunnels” almost always means Ben Dinh unless Ben Duoc is named.
Sample plans for a Cu Chi Tunnels day
Two ways to spend the day
Plan A is an early half day at Ben Dinh. Leave District 1 at 7 a.m. to arrive before the main groups, walk the site, crawl one or two sections and eat cassava at the kitchen. You are back in the city by early afternoon for lunch and the War Remnants Museum.
Plan B uses a private car to Ben Duoc: a morning drive, a slower visit to the tunnels and the memorial temple, and lunch on the way back. Travellers who want time to read the displays will prefer it. Either plan can stretch to a full-day tour that adds the Cao Dai Holy See in Tay Ninh, though most of that day is spent in the vehicle.
Whichever plan you choose, the road journey sets the rhythm of the day. Expect around one and a half to two hours each way by road from District 1, longer to Ben Duoc and in weekday rush hour, so a half-day tour really takes five to six hours door to door. The speedboat option along the Saigon River cuts the journey time and adds a river view, but costs more. Public buses do reach the area with a change in Cu Chi town, which suits budget travellers with patience, but the last stretch to the sites can need a motorbike taxi and leaves no guide to explain what you see. Pick Plan A if you want the classic experience and a free afternoon; pick Plan B if you prefer fewer crowds and the original tunnel sections.
Cu Chi Tunnels tickets, opening hours and costs
Both sites open daily (October 2026 hours), generally from 7 a.m. to 5 p.m. Published foreign-visitor prices are around 110,000 VND per person for Ben Dinh and around 90,000 VND for Ben Duoc, but figures differ between sources and older guides quote other amounts, so treat these as a guide and confirm at the gate or with your tour operator.
Tour prices include entry and a guide; check whether lunch and water are included. A shared group tour from central Ho Chi Minh City is the cheapest option with transport; private car tours cost more but let you set the start time, which is the easiest way to arrive at opening. Half-day tours by speedboat along the Saigon River sit at the top of the price range.
Extras on site include the firing range, which is paid separately and charges per bullet with a minimum purchase, and drinks and snacks at kiosks. Carry Vietnamese dong in small notes, since card machines are not reliable at kiosks. Budget for a tip for your guide if the tour was good, and for bottled water, which you will need in the humidity.
Allow about two to three hours at either site for the guided loop, the short tunnel crawl and the exhibits. Ben Duoc is further from the city, so the round trip is longer, but it is usually quieter.
Best time to visit the Cu Chi Tunnels
Go in the dry season from December to April and arrive early in the morning. Paths are firm, the forest is less humid and the first hour is far quieter.
From May to November short, heavy afternoon showers are common. The site stays open, but paths turn slippery and the tunnels feel even more humid. A morning visit usually stays dry. Around Tet, the Lunar New Year, domestic visitor numbers rise.
Time of day matters as much as the month. Most group tours from the city arrive mid-morning, so the tunnels and the firing range are busiest from about 10 a.m. to early afternoon. Arriving close to opening, or joining an afternoon tour that reaches the site after the morning groups leave, gives a calmer visit. March and April are the hottest months of the dry season, so start early and wear light, breathable clothes and closed shoes that can get dusty or muddy.
Weekdays are quieter than weekends, when local families and school groups visit. Avoid the national holidays on 30 April and 2 September as well as Tet, when the roads out of the city are also congested.
Practical tips for visiting the Cu Chi Tunnels
- Dress for dirt. Closed shoes with grip and light, long trousers. Red clay stains, so avoid white clothing.
- Bring water and repellent. The forest is humid and mosquitoes are active at dawn and dusk in any season.
- Beat the groups. Arrive at opening time or late in the afternoon. Mid-morning at Ben Dinh is the busiest window.
- Read up first. Visit the War Remnants Museum in the city before or after. It gives the context the tunnel tour skips.
- Ask before photos. Ask permission before photographing staff, and be respectful at the memorial temple at Ben Duoc.
- Children. Older children usually enjoy the visit. Younger ones may find the dark tunnels, traps and gunfire upsetting.

The firing range is loud across the whole Ben Dinh site, and anyone sensitive to noise, including small children and some veterans, may want ear protection or to keep the visit short. Toilets and small shops are available at both entrances, but there is little shade on the walk between exhibits, so a hat helps in the dry season.
