30 Things You Should Never Do When Traveling Abroad

Here’s a detailed guide on 30 things to avoid when you travel abroad, so your trip stays smooth, safe, and memorable rather than stressful.

I’ll group them into practical categories so it’s easier to follow.

1. Documentation & Legal Issues

Traveling without checking visa requirements
Some countries require a visa in advance. Arriving without one could mean being denied entry.
Ignoring passport validity
Many countries require your passport to be valid for at least 6 months after your arrival.
Not carrying photocopies of important documents
If you lose your passport, having a copy speeds up the replacement process.
Breaking local laws unknowingly
Some laws abroad can be unusual (e.g., chewing gum in Singapore, vaping in Thailand). Research before you go.
Overstaying your visa
Even one extra day can lead to fines, blacklisting, or deportation.

Exchanging money at airports
They often have the worst rates. Use ATMs or local exchange offices.
Relying on one payment method
Always carry a mix of cash and cards in case one doesn’t work.
Carrying too much cash
If lost or stolen, it’s gone forever. Carry only what you need for the day.
Not informing your bank about travel
Your card may get blocked for suspicious transactions.
Falling for currency scams
Some scammers give counterfeit notes or shortchange tourists. Double-check the amount.

Skipping travel insurance
Medical treatment abroad can be extremely expensive without coverage.
Ignoring food and water safety
In some countries, tap water isn’t safe to drink. Avoid raw or street food in unhygienic places.
Not packing essential medication
Your prescription might not be available abroad or may require special approval.
Not knowing emergency numbers
"911" isn’t universal—learn the local emergency number.
Underestimating jet lag and exhaustion
Overpacking your first days with activities can leave you drained.

Disrespecting local customs or dress codes
In conservative countries, revealing clothing can be offensive.
Public displays of affection
In some cultures, holding hands or kissing in public is frowned upon or even illegal.
Pointing or touching without permission
Gestures like pointing at people or touching their head can be disrespectful.
Assuming everyone speaks English
Learn a few basic phrases in the local language—it shows respect.
Being noisy or disruptive
Loud behavior may be seen as rude in certain cultures.

Not learning local transportation rules
In some cities, jaywalking can result in heavy fines.
Taking unlicensed taxis
These can overcharge you or be unsafe. Use official taxi stands or apps.
Not keeping track of belongings on public transport
Pickpocketing is common in crowded areas.
Driving without knowing local traffic laws
Different road signs, speed limits, or side-of-road driving can cause accidents.
Ignoring travel advisories
Political unrest or unsafe weather conditions can make certain areas risky.

Using unsecured public Wi-Fi
Hackers can steal personal information—use a VPN.
Not having an offline map
You might lose internet connection in remote areas.
Not having a backup charger or power bank
You don’t want your phone dying during emergencies.
Sharing your location publicly on social media in real-time
This can attract thieves who know you’re away from your hotel.
Not keeping embassy contacts
If you lose your passport or face legal trouble, the embassy is your lifeline.

✅ Pro Tip: The biggest mistake is assuming “it won’t happen to me.” Prevention is always better than dealing with trouble abroad.
