15 Common Mistakes International Tourists Make on Their First Trip to Vietnam (And How to Avoid Them)

Vietnam is a country of breathtaking beauty and profound culture, but first-time visitors can sometimes leave with a skewed experience. Relying too heavily on influencer fantasies, attempting a frantic “show-run” tour, and missing out on street food are just a few pitfalls that can derail a trip.

1. Trying to Conquer the Entire Country in One Trip

Looking at a map, Vietnam appears long and narrow. In reality, its area is comparable to Italy or Japan. The distance from Hanoi to Ho Chi Minh City is over 1,700 km–a journey that takes over two hours by flight or over 30 hours by road.

The Fix:

Focus on one or two regions. For a two-week trip, choose either the North (Hanoi, Ha Long, Sapa, Ha Giang) or the South (HCMC, Mekong Delta, Dalat, Phu Quoc). Depth over breadth is the key.

2. Underestimating the Weather and Seasons

Vietnam’s weather is highly regionalized. It’s not just “sunny” or “rainy” across the country. You could have a cold, drizzly winter in Hanoi (Dec-Feb), be facing extreme heat in the Central Provinces (Apr-Aug), and encounter monsoon floods (Sep-Nov) all at the same time.

The Fix:

Research the specific weather patterns for your chosen region and month. Pack layers, a good rain jacket, and the right footwear. Embrace the weather–a misty day in Sapa or a warm downpour in Hoi An can be magical.

3. Getting Angry at the Weather

Following on from point 2, a common mistake is letting bad weather ruin your trip. Typhoons can disrupt travel, and heatwaves can be exhausting.

The Fix:

Build flexibility into your itinerary. Have a list of indoor activities (museums, cooking classes, cafes) as a backup. Remember, locals live with this climate every day–follow their lead and adapt.

4. Succumbing to “Fear of Missing Out” (FOMO)

The pressure to see every single “must-see” spot from a blog list can turn a vacation into a stressful marathon. Chasing every hotspot often means battling crowds and experiencing local fatigue.

The Fix:

Prioritize what genuinely interests you. Would you prefer a quiet day cycling through rural villages or a busy day seeing a famous cave? Curate your own experience, not someone else’s.

5. Blindly Trusting Social Media Influencers

Many travelers have disappointing experiences because a TikTok clip or Instagram post was misleading. Social media algorithms prioritize viral, aesthetically pleasing content, not necessarily honest or in-depth reviews.

The Fix:

Seek out content creators who live in Vietnam long-term. Their advice will be more nuanced, practical, and less focused on selling a dream. Use influencer content for inspiration, not as a strict itinerary.

6. Overlooking Street Food Over Hygiene Fears

Avoiding street food is perhaps the biggest culinary mistake. The most authentic, delicious, and memorable Vietnamese dishes are often found at humble street-side stalls specializing in just one thing.

The Fix:

Use common sense. Eat at stalls with high turnover (a busy crowd means fresh food) where you can see the food being cooked. Avoid raw vegetables that may have been washed in tap water if you have a sensitive stomach. Start with cooked dishes like phở, bún chả, or bánh mì.

7. Refusing to Get a Local SIM or eSIM

Relying solely on spotty hotel Wi-Fi severely limits your freedom. It makes navigating with Google Maps, translating menus, and booking last-minute rideshares like Grab difficult.

The Fix:

Get a local SIM card at the airport (from Viettel, Vinaphone, or Mobifone) for about $10-15 for a month of ample data. Even easier, download an eSIM before you arrive using an app like Airalo or Yesim. Being connected is cheap and liberating.

8. Dismissing the Value of a Good Guidebook

In the age of AI-generated listicles and fake reviews, a well-researched guidebook from a reputable publisher (Lonely Planet, Rough Guides, DK Eyewitness) is a treasure trove of reliable, curated information.

The Fix:

Use a guidebook for its deep cultural context, reliable hotel and restaurant recommendations, and meticulously checked practical details. Use the internet for real-time reviews and updates. They complement each other perfectly.

9. Not Learning a Few Basic Vietnamese Phrases

While you can get by in tourist areas with English, making a small effort with the local language is a sign of respect and will be met with warm smiles and better service.

The Fix:

Learn a few essentials:

• Xin chào (Sin chow) – Hello
• Cảm ơn (Cam on) – Thank you
• Bao nhiêu tiền? (Bow nyew tee-en?) – How much?
• Một, hai, ba (Mot, hi, ba) – One, two, three

10. Underestimating the Traffic in Big Cities

The infamous motorbike chaos in Hanoi and HCMC can be overwhelming. The instinct is to freeze on the curb.

The Fix:

To cross the street, walk slowly and steadily. Don’t run, don’t stop, don’t retreat. The traffic will flow around you predictably. Watch the locals and do as they do.

11. Only Using Ride-Hailing Apps in Cities

While Grab and Gojek are fantastic and prevent overcharging, relying on them exclusively means you might miss out on experiences in smaller towns or the countryside where they aren’t available.

The Fix:

Be open to using local taxis (choose reputable brands like Mai Linh or Vinasun) and especially Xe Ôm (motorbike taxis). Negotiate the price beforehand or insist on the meter for taxis.

12. Forgetting to Carry Cash

Vietnam is still very much a cash-based society, especially in local markets, for street food, and for small purchases. Even if a place accepts cards, there’s often a fee.

The Fix:

Always carry a stack of smaller denomination Vietnamese Dong (VND). Use ATMs to withdraw cash (they are everywhere), but inform your bank of your travel plans first.

13. Overpacking and Bringing the Wrong Shoes

Dragging a huge suitcase over the uneven pavements and into small taxis is a hassle. The wrong footwear can ruin a day of exploring.

The Fix:

Pack light, breathable clothing. Your most important item will be comfortable walking shoes (sandals are not enough for a day of touring). A pair of sturdy sandals like Tevas or Keens are perfect for both cities and beaches.

14. Ignoring Local Customs and Etiquette

While Vietnamese are incredibly forgiving of tourists, being mindful of basic etiquette shows respect.

The Fix:

• Dress modestly at temples and pagodas (cover shoulders and knees).
• Remove your shoes when entering someone’s home and sometimes even shops.
• Don’t public lose your temper; it causes you and others to “lose face.”

15. Only Staying in International Resort Bubbles

While Vietnam’s beach resorts are stunning, staying exclusively within their walls means you’ll experience a sanitized, international version of the country, not the real, vibrant Vietnam.

The Fix:

Balance your trip. Spend a few days at a resort relaxing, but make sure to also book a homestay in the Mekong Delta or a family-run hotel in Hoi An’s Ancient Town to connect with local life and culture.

By avoiding these common missteps, your first trip to Vietnam will be less about checking boxes and more about collecting genuine, lasting memories of one of Southeast Asia’s most captivating countries.
