The first few days in Korea can feel exciting… and a little confusing at the same time.
Everything looks modern and easy — until you realize small things don’t work the way you expected.
I didn’t make huge mistakes.
But there were a few moments where I thought,
“Ah… I should have known that.”
Assuming Everything Works Like Your Country

Korea is modern, yes.
But it’s not always intuitive.
Subway systems, payment methods, even simple things like trash bins —
they don’t always work the way you expect.
At first, I kept trying to “figure it out my way.”
That didn’t work very well.
Things got easier once I stopped assuming and just followed what locals were doing.
Not Carrying Enough Cash

Cards are widely accepted in Korea.
But not everywhere.
Small street food stalls, local markets, or older shops sometimes prefer cash.
I remember standing there, ready to pay… and realizing my card wasn’t an option.
Since then, I always carry a small amount of cash — just in case.
To avoid this, just take a moment to observe how locals behave and follow their pace.
Underestimating Walking Distance

This one surprised me.
Places that look close on the map… aren’t always that close.
Streets can be longer than expected, and underground subway paths can take time.
What I thought would be a “quick walk” sometimes turned into 20 minutes.
Now I always check directions more carefully.
Missing Last Transportation
One mistake people don’t think about — until it happens.
Subways don’t run all night.
If you stay out late and miss the last train, your options become limited.
Taxis are available, but they can be harder to find during busy hours.
If you plan to stay out late, it’s worth checking transportation ahead of time.
You can also look at routes and schedules on this option on Klook to avoid getting stuck.
A simple way to handle this is to watch what others do and adjust accordingly.
Trying to Do Too Much in One Day
It’s tempting.
Seoul alone has so much to see — and it feels like you should do everything.
I tried that at first.
And honestly, it just made the day exhausting.
Things became much better when I slowed down and focused on fewer places.
Small Mistakes That Stay With You
These aren’t big problems.
They don’t ruin your trip.
But they stay in your memory — the small moments where things didn’t go as smoothly as they could have.
