What to Do in Ho Chi Minh City in 4 Days: War Remnants, Cu Chi Tunnels, and Saigon's Best Eats

After dropping your bags at the hotel (the classic 4-day route starts right here in District 1), step out into the heat. The cathedral, built entirely from red bricks shipped from France, anchors the square. Walk over to the Central Post Office next door. Inside, a giant portrait of Ho Chi Minh watches over a cavernous hall where people still queue to send letters. The phone booths and old maps on the walls make this feel like a scene from the 1960s.

The Reunification Palace (formerly Independence Palace) is frozen in time. Walk through the cabinet room, the helipad, and the basement war room where tanks were tracked on maps. Then head a few blocks to Bitexco Financial Tower. The elevator ride to the Sky Deck is a thrill of its own. From the top, you can trace the Saigon River and spot the city's patchwork of old villas and new skyscrapers. Entry to the palace is 200,000 VND (about 8 USD); the Sky Deck is 200,000 VND.

The War Remnants Museum is not an easy visit. It tells the story of the Vietnam War from the Vietnamese perspective with unflinching clarity. Start in the courtyard with the tanks, helicopters, and a guillotine. Then move inside to the galleries. One room is covered with photographs taken by war correspondents who died. Another has glass jars containing the preserved remains of birth defects caused by chemical agents. Allow at least two hours. Entry is 40,000 VND (about 1.50 USD).

Ben Thanh Market is chaos orchestrated perfectly. Walk through the food hall and find a counter for pho or goi cuon (fresh spring rolls). Try the grilled pork skewers from a lady near the central fountain. The vendors are used to tourists, so bargain with a smile. Grab a glass of ca phe sua da (iced coffee with condensed milk) to cool down. If you want to bring something home, the dried fruit and spices are easy to pack. A bowl of pho here costs about 50,000 VND (2 USD).

The Saigon Opera House, a French colonial jewel on Dong Khoi Street, hosts the A O Show nightly. This performance blends circus, dance, and traditional Vietnamese music using bamboo poles, silk ropes, and rice baskets. The show runs about 60 minutes and doesn't use words, so it's easy to follow. Tickets start at 600,000 VND (about 25 USD). Before the show, grab dinner at Ngon 138, a social-enterprise restaurant a short walk away that serves dishes like bun bo Hue and clusters of tiny spring rolls.

A half-day tour out to the Cu Chi Tunnels shows you a side of the war that textbooks can't capture. The tunnels were a living network for Viet Cong soldiers, complete with kitchens, hospitals, and conference rooms. On the tour you'll see the tiny trap doors, hear how crude weapons were made, and even get a chance to crawl through a 100-meter section. Guides explain the daily life of the soldiers. At the end, try a piece of boiled cassava dipped in groundnut, their wartime meal. Tours from District 1 cost around 200,000 to 400,000 VND (8 to 16 USD) and include transport and guide.

Your final breakfast in Saigon should be at Banh Mi Huynh Hoa. The line looks long, but it moves fast. Order one banh mi thit (mixed meat) and watch the woman assemble it: two kinds of pork roll, pâté, shredded carrots and daikon, cucumber, cilantro, and a secret drizzle of sauce. The baguette is crisp on the outside and airy inside. At 50,000 VND (2 USD), it might be the best value meal in all of Vietnam. Eat it on the curb or take it to a park. Then grab a taxi for your airport transfer, saluting the city that never sleeps.
