Why Explore the Cu Chi Tunnels?
Located 30 to 40 km from Ho Chi Minh City, Cu Chi is renowned for its intricate tunnel system utilized by the Viet Cong during the Vietnam War. The two primary sites are Ben Dinh and Ben Duoc. While Ben Dinh is more accessible for tourists, Ben Duoc offers a quieter experience with fewer visitors. When I visited, it was surprisingly uncrowded!
Some sources suggest that Ben Dinh was created solely for tourists, while Ben Douc is part of the original tunnel system. Lonely Planet mentions that Ben Douc has been modified for tourist access but remains less commercialized. Expect tight spaces inside the tunnels—definitely not for those who are claustrophobic!
Although tours to Ben Dinh are readily available, public buses to Ben Douc provide an authentic experience without the masses, complete with air conditioning!
Details to Consider:
Duration: 6-8 hours
Overall Expenses: $5.15 USD
Bus fare – 32,000 dong roundtrip ($1.37 USD)
Entrance fee – 90,000 dong ($3.78 USD)

Bus Directions to Ben Douc Tunnel from Ho Chi Minh City
Begin your journey by taking Bus 13 from the Cong Vien 23/9 bus terminal in District 1, located just beyond September 23rd Park. This terminal is quite large, so it's hard to miss. Here's the Google Maps location: 210Bis/, 7 Nguyễn Trãi, Phường Phạm Ngũ Lão, Quận 1, Hồ Chí Minh, Vietnam.
Ride the bus until the end of the route in Cu Chi, which may take around 1.5-2 hours depending on traffic. (Cost: 10,000 dong each way)
Once you reach Cu Chi, switch to Bus 79 and request the driver to let you off at Ben Douc. Expect some fellow travelers on board, as most will be heading to the same destination. This part of the trip lasts about 30-45 minutes. (Cost: 6,000 dong each way.)
Both bus rides are air-conditioned, with a total fare of $1.37 USD.
After disembarking, follow the signs to the entrance. It's a short 10-minute walk to the tour starting point. The entrance fee is 90,000 dong ($3.78 USD).

Info about the Ben Douc Tour
Our English-speaking tour had around 10 participants. The path meanders through the woods, making it easy to explore various tunnels and exhibits. Initially, we watched a propaganda video, followed by displays of traps and models illustrating how the tunnels functioned. The first tunnel is quite short but worth the experience. There are additional tunnels to explore, including a lengthy one at the end—avoid it if you're claustrophobic. Expect to crouch most of the time; my backpack was a bit cumbersome, but the guide recommended keeping it with me for safety.
Near the bus stops, you'll find a few shops and a restaurant by the entrance. (Consider bringing your own snacks and drinks, as prices can be higher here!) Two roads lead to the entrance; we were dropped off at the farther one and walked back. (Check the map at the end of this post.) A few old helicopters and tanks are on display near this entrance. We only waited about 10 minutes for the return bus. I heard the last bus departs around 7 p.m., but it's best to confirm when you get off the bus!

Travel Time to Cu Chi Tunnels from Ho Chi Minh City
We departed around 10 a.m. and returned around 5-6 p.m. The traffic on our return was the worst I've ever encountered. We sat in place for 30-45 minutes. Walking wasn't an option since motorbikes crowded the sidewalks! (Watch the video in my Instagram story on Vietnam for a glimpse!) To enhance your experience, I suggest starting your day earlier and returning sooner.
All in all, this was one of my best days in Vietnam. It was an excellent escape from the hustle of Ho Chi Minh City and a more genuine visit. Plus, taking the bus was enjoyable and allowed me to see more of the area!

Download Offline Maps
I recommend downloading the free Maps.me app to save the Vietnam map offline. I marked the Ben Douc tunnels on the map and tracked our route to know when to get off. Ensure you load the map before starting your journey, as it will still update without service. (The driver will inform you where to disembark, so even without your phone, you won't miss your stop!)
