Crucial Travel Mistakes to Avoid in South Korea + What to Do Instead
Previously, we have discussed about all the mistakes to avoid when you travel to South Korea from the cultural aspect. But sometimes, there are simple things you might not expect to have such a massive impact on your travel to this beautiful country.
Therefore, here are some of the crucial mistakes you must pay attention and avoid when you travel to South Korea and what to do instead.
1. Not Knowing Public Trash Disposal Rules
First and foremost, South Korea takes waste disposal seriously, and you’ll quickly notice that public trash cans can be surprisingly hard to find. If you’re used to tossing your empty drink cups in any bin on the street, you might be in for a shock.
Therefore, when in South Korea, keep a small bag with you for waste until you locate a trash can—often found at subway stations or inside convenience stores. Then, make sure to separate recyclables and general trash if you see the designated bins.

And most importantly, if you’re not used to separating your waste, please make sure you educate yourself on these separate bins,
2. Assuming Google Maps Works Perfectly
Secondly, Google Maps might be your best friend back home, but in South Korea, government restrictions limit its accuracy. That’s why you could end up hopelessly lost if you rely on Google Map for directions in South Korea.
Therefore, when in South Korea, make sure to download Naver Maps or KakaoMap. These travel apps offer precise navigation, real-time bus and subway info, and they’re frequently updated with local data. They will then guide you to your travel destination with more precise location.

3. Wearing Revealing Clothing in Certain Situations
Thirdly, while shorts are generally acceptable, showing too much cleavage or wearing overly revealing outfits can sometimes draw unwanted attention in South Korea. That is particularly when you travel to conservative or traditional settings like temples, traditional markets, or rural areas.

That is why it’s better to pack outfits that strike a balance between comfort and modesty. If you plan to wear something more revealing, consider carrying a light jacket or shawl so you can easily cover up when needed, depending on the place or situation.
4. Expecting Everyone to Speak English
While English proficiency is growing—especially among the younger generation—many locals aren’t comfortable speaking English. This can lead to confusion, especially in smaller shops or rural areas.
Therefore, make sure to learn a few basic Korean phrases such as “안녕하세요” (Hello, annyeonghaseyo) and “감사합니다” (Thank you, gamsahamnida). Additionally, keep a translation app (like Papago) handy for quick help.
5. Jaywalking or Ignoring Traffic Signals
Yes, there might be times when you feel tempted to cross the street if there aren’t many cars around. However, jaywalking can lead to a hefty fine, and South Korea’s roads are closely monitored by CCTV.
So, even if there street is empty, always wait for the pedestrian signal to turn green no matter how much you’re in a hurry. It might feel tedious, but it’s safer and will keep you from breaking local laws.

6. Being Unaware of Korea’s Strict Drug Laws
Meanwhile, you would also need to pay attention on what drugs you are carrying during your travel. Some travelers find themselves in legal trouble when they bring medications that are legal at home but banned in South Korea. Stimulants like Adderall or certain prescription sleeping aids might not be allowed, even with a prescription.

Double-check the Korean customs website or contact the local embassy to confirm which medications you can bring. When in doubt, carry a prescription note and declare your meds upon arrival.
7. Trying to Tip Waiters or Taxi Drivers
Tipping is customary in many countries, but not in South Korea. In fact, leaving a tip will possibly confuse or even embarrass your server or driver, especially with the recent debate about tipping culture in the country.
If you’re grateful for excellent service, express it with a heartfelt “Thank you” or “감사합니다.” This is enough to show your appreciation. Some upscale hotels and tourist-focused services may include a small service charge, but outside of that, no tip is necessary. Get yourself acquainted with the tipping culture in South Korea so you don’t make mistakes during your travel.

8. Exiting the Subway Without Checking Exit Numbers
At the same time, please remember that large subway stations in major cities like Seoul or Busan can have multiple exits—sometimes more than a dozen. So exiting from the wrong one can leave you several blocks away from your destination.
That is why before hopping on your train, figure out which exit number is closest to your destination. Apps like Naver Maps or KakaoMap will typically list the best exit to take.

9. Not Carrying Cash
In South Korea, credit cards are widely accepted. However, smaller businesses, street food stalls, and certain mom-and-pop restaurants might still be cash-only.
Hence, it’s crucial to keep some Korean won (₩) in your wallet for those moments when card payment isn’t an option. Convenience stores and ATMs are easy to find if you need to withdraw more cash.

10. Smoking in the Wrong Places
Last but most importantly, smoking regulations in South Korea are extremely strict, especially in major city centers. You’ll find designated smoking areas, and you can be fined if you’re caught lighting up anywhere else.
Therefore, look for “No Smoking” signs on the street, in cafes, and near bus stops so you don’t make mistakes during your travel to South Korea. If you’re a smoker, head to a designated area—usually clearly marked or inside smoking lounges.

Finally, traveling to South Korea can be one of the most magical experiences you’ll ever have—especially if you’re a fan of K-pop, K-dramas, or simply fascinated by its rich culture and modern city life. The key to a smooth and memorable adventure is avoiding these common yet crucial travel mistakes. By knowing the unspoken rules and quirks of Korean etiquette, you’ll blend in faster, avoid embarrassing moments, and maximize your enjoyment.
So, go ahead and live your South Korean dream! Keep these tips in mind, and you’ll spend more time indulging in delicious Korean BBQ, strolling through ancient palaces, and belting out your favorite tunes at noraebang (karaoke) instead of dealing with preventable mishaps.
Your South Korea journey awaits—make it everything you’ve ever dreamed of and more. Bon voyage!
