21 Things You Must Not Do on an International Trip

You’re here because you’re ready to embark on an international adventure and want to make sure you do it right. 

Trust me, preparation and awareness are key to having a smooth and enjoyable trip abroad. I’ve learned this the hard way.

On one of my early trips, I found myself at the airport with way too many bags, no travel insurance, and absolutely no idea about the local customs of my destination. 

It was a recipe for disaster. I ended up paying exorbitant fees for overweight luggage, spent a night at a hospital without insurance, and managed to offend a few locals along the way. 

Not my finest hour, but it taught me a lot about what not to do when traveling internationally.

That’s why I wrote this article—to share those lessons and help you avoid the same mistakes. 

You’ll discover 21 things you absolutely must not do on an international trip. These tips will save you time, money, and a whole lot of stress. 

From overpacking to ignoring local customs, I’ve got you covered. 

Let’s dive in and make sure your next trip is nothing short of amazing.

1. Don’t Overpack

Packing light isn’t just about convenience. It’s about mobility and freedom. 

When you overpack, you’re weighed down by heavy bags, which can make navigating airports, trains, and buses a nightmare. 

I’ve been there, lugging around a massive suitcase through narrow streets and crowded subways, wishing I’d left half of it at home.

When you pack light, you can move around more easily, save on baggage fees, and have more room for souvenirs. 

Plus, it’s easier to keep track of your belongings. 

On a trip to Tokyo, I packed just a carry-on and a backpack. 

It made getting around the city’s efficient yet crowded transit system so much easier. 

I had everything I needed without the burden of extra weight.

2. Don’t Forget to Check Visa Requirements

Visa requirements vary from country to country, and failing to check them can lead to serious problems. 

Imagine arriving at your dream destination only to be denied entry because you didn’t have the right visa. 

I once met a fellow traveler in Bangkok who had to turn around and fly back home because he didn’t realize he needed a visa in advance.

Always check visa requirements well before your trip. 

Some countries offer visas on arrival, while others require you to apply weeks or even months in advance. 

It’s also a good idea to keep digital and physical copies of your visa and other important documents.

3. Don’t Ignore Travel Insurance

Travel insurance might seem like an unnecessary expense, but it’s crucial. 

It can cover medical emergencies, trip cancellations, lost luggage, and more. 

I learned this the hard way when I got food poisoning in Mexico. Without insurance, I ended up paying a hefty bill for a hospital visit and medication.

On another trip, my friend had his bag stolen, and his travel insurance covered the cost of his lost items. 

Travel insurance gives you peace of mind, knowing you’re covered in case something goes wrong. 

It’s a small price to pay for the security it offers.

4. Don’t Exchange Money at the Airport

Airport currency exchange kiosks often charge higher fees and offer poorer exchange rates than other options. 

I once exchanged money at the airport in Paris and later found out I lost a significant amount to fees and unfavorable rates.

Instead, consider withdrawing cash from an ATM at your destination or using a credit card with no foreign transaction fees. 

This way, you get a better exchange rate and avoid extra fees.

Some banks even partner with international banks to offer fee-free withdrawals.

5. Don’t Rely Solely on Your Phone

While smartphones are incredibly useful for navigation, communication, and research, they aren’t infallible. 

Batteries die, phones get lost or stolen, and sometimes you just can’t get a signal. 

On a trip to the mountains in Peru, my phone died and I had no physical map or way to contact anyone.

Always have physical copies of important documents like your passport, visa, and hotel reservations. 

It’s also wise to carry a paper map of your destination. 

This way, if your phone fails, you still have access to vital information.

6. Don’t Neglect Local Customs and Etiquette

Respecting local customs and etiquette shows that you’re a considerate and aware traveler. 

Failing to do so can lead to uncomfortable situations or even offend the locals. 

In Japan, I once made the mistake of talking on my phone in a quiet train carriage, which is considered rude there. 

The disapproving looks were enough to make me realize my mistake.

Researching local customs before you go helps you avoid these faux pas. 

Whether it’s dress codes, tipping practices, or social norms, understanding and respecting these customs enriches your travel experience and fosters positive interactions with locals.

7. Don’t Be Afraid to Try Local Food

One of the best parts of traveling is experiencing new cuisines. 

Yet, many travelers stick to what they know, missing out on unique culinary experiences. 

On my first trip to Thailand, I was hesitant to try street food, fearing it might make me sick. 

But once I took the plunge, I discovered some of the most delicious dishes I’ve ever had, like Pad Thai from a local market.

Trying local food is an adventure in itself. It allows you to explore the culture through its flavors. 

Don’t shy away from food you can’t pronounce or ingredients you’ve never heard of.

Some of my most memorable meals have been from hole-in-the-wall eateries that served authentic, mouth-watering dishes.

8. Don’t Forget to Notify Your Bank

Notifying your bank of your travel plans can save you from the frustration of a blocked card. 

Banks often flag foreign transactions as suspicious, which can lead to your card being frozen. 

On a trip to Spain, I made several purchases without informing my bank.

Suddenly, my card stopped working, leaving me scrambling to contact my bank and sort out the issue.

To avoid this, inform your bank of your travel dates and destinations. 

Many banks offer the option to do this online or through their app.

This ensures your transactions go through smoothly, and you can enjoy your trip without financial hiccups.

9. Don’t Skip Researching Your Destination

Researching your destination helps you understand the culture, attractions, and local customs, enhancing your travel experience.

Before heading to Japan, I spent time learning about its etiquette, transportation system, and must-see spots. 

This preparation made navigating the country easier and more enjoyable.

Knowing key facts about your destination can prevent misunderstandings and enrich your journey. 

It can lead you to hidden gems, local events, and authentic experiences that you might otherwise miss.

10. Don’t Underestimate Language Barriers

Language barriers can pose challenges, but they’re also part of the adventure. 

On a trip to Italy, I struggled to order food at a local restaurant because I didn’t know the language. 

After some gesturing and a few laughs with the waiter, I ended up with a delicious meal and a memorable experience.

To overcome language barriers, learn a few basic phrases of the local language. 

Use translation apps and carry a pocket phrasebook. 

These small efforts can make a big difference in communicating with locals and enhancing your travel experience.

11. Don’t Leave Home Without a Backup Plan

Having a backup plan is essential for handling unexpected situations. 

Travel plans can change due to weather, transportation issues, or other unforeseen circumstances. 

On a hiking trip in the Swiss Alps, my original route was closed due to heavy snowfall. 

Thankfully, I had researched alternative trails, and my backup plan allowed me to continue my adventure without missing a beat. A contingency plan ensures that you’re prepared for surprises, making your journey smoother and less stressful.

12. Don’t Be Careless with Your Valuables

Keeping your valuables safe is paramount when traveling. 

Losing important items like your passport, wallet, or phone can ruin your trip. 

I once lost my wallet on a crowded bus in Buenos Aires, leaving me stranded without money or identification. 

To avoid such mishaps, use a money belt or a secure bag, and always be mindful of your belongings, especially in busy areas. 

Splitting up your valuables, such as keeping some cash and a backup credit card in a separate location, can also be a lifesaver if something goes missing.

13. Don’t Overschedule Your Itinerary

While it’s tempting to pack your itinerary with activities and sights, overscheduling can lead to burnout and stress. 

During a trip to Rome, I planned to visit multiple landmarks in one day, leaving no room for rest or spontaneous exploration. 

By midday, I was exhausted and unable to fully enjoy the experience. 

A flexible schedule allows you to immerse yourself in the moment, discover unexpected attractions, and truly enjoy your trip. 

Balance your plans with downtime to relax and soak in the ambiance of your destination.

14. Don’t Ignore Health Precautions

Taking health precautions seriously is vital for safe and enjoyable travel. 

This includes getting necessary vaccinations and health checks before your trip. 

On a journey to Southeast Asia, I ignored advice to get vaccinated for certain diseases and ended up with a severe case of food poisoning that landed me in a hospital. 

This experience underscored the importance of health precautions. 

Ensuring you’re up-to-date with vaccinations and carrying a basic first aid kit can prevent health issues from derailing your trip. 

Be proactive about your health to ensure you can fully enjoy your adventures.

15. Don’t Forget to Keep Track of Time Zones

Being aware of time zone differences is crucial for staying on schedule. 

During a trip to Spain, I forgot to adjust my watch and ended up missing a connecting flight. 

The confusion and the cost of booking a new ticket taught me the importance of syncing my devices and setting reminders for different time zones. 

Whether it’s catching flights, attending meetings, or connecting with loved ones back home, knowing the local time helps you stay organized and avoid unnecessary stress.

16. Don’t Neglect Travel Safety Tips

Travel safety is paramount, especially for solo travelers. 

Basic safety measures, like staying aware of your surroundings and avoiding poorly lit areas at night, can make a big difference. 

On a trip to Istanbul, I followed advice to keep my bag closed and my valuables hidden. 

One evening, a pickpocket attempted to grab my wallet, but my precautions thwarted the attempt. 

Simple actions like these help you stay safe and enjoy your travels with peace of mind.

17. Don’t Be Afraid to Ask for Help

Asking for help when needed can turn challenging situations into positive experiences. 

While navigating the crowded streets of Marrakech, I felt completely lost. 

I hesitated to ask for directions but finally approached a friendly local who not only guided me to my destination but also shared valuable tips about the city. 

Most people are willing to help if you ask politely. 

This interaction not only resolved my problem but also enriched my travel experience with a genuine connection.

18. Don’t Forget to Stay Connected with Loved Ones

Keeping in touch with family and friends while traveling provides comfort and security. 

During a solo trip to Vietnam, I made it a habit to check in with my family every evening. 

This routine offered reassurance to them and a sense of companionship for me. 

Regular updates help you stay grounded and provide a safety net in case something goes wrong. 

Whether through social media, messaging apps, or phone calls, staying connected enhances your travel experience and eases any concerns from those back home.

19. Don’t Ignore Sustainable Travel Practices

Practicing eco-friendly travel is essential for preserving the beauty of the destinations we visit. 

On a trip to Costa Rica, I chose to stay at eco-friendly lodges, use public transport, and minimize plastic use. 

These small actions contributed to the local economy and environment. 

By supporting sustainable practices, you help protect the places you love to explore. 

Simple steps like carrying a reusable water bottle, choosing green accommodations, and respecting wildlife can make a significant impact.

20. Don’t Let Fear Hold You Back

Fear often prevents us from experiencing new adventures. 

On a trip to New Zealand, I was terrified of bungee jumping but decided to face my fear. 

The adrenaline rush and the sense of accomplishment afterward were incredible. 

Conquering travel-related fears opens up a world of possibilities and enriches your journey. 

Embrace new experiences, whether it’s trying new cuisine, navigating a foreign city, or engaging in adventure sports. 

Pushing past fear leads to growth and unforgettable memories.

21. Don’t Forget to Have Fun and Enjoy the Journey

Above all, remember to enjoy your travel experience. 

It’s easy to get caught up in planning and logistics, but taking time to savor the moments makes your trip truly special. 

One of my favorite memories is watching the sunset over the Grand Canyon. 

I set aside my itinerary and simply soaked in the breathtaking view. 

Travel is about more than just ticking off destinations; it’s about embracing the journey, making connections, and creating lasting memories.
