6 Mistakes I Made Travelling Thailand (So You Don't Have To)

Most Thailand "mistakes" articles are the same recycled list.

This one is different: I only want to include things I actually did, struggled with or learned from while travelling.

1. Underestimating the Thai sun

What I'd do differently

• sunscreen before I leave the room
• reapply it rather than pretending one application lasts all day
• carry water
• use shade
• do not schedule every outdoor activity at the hottest part of the day

The frustrating part is that this mistake is so avoidable.

2. Letting one physical bank card matter too much

Travelling taught me how vulnerable you are when one small piece of plastic becomes your route to all your money.

What I'd do differently

• main card and backup card
• different accounts/providers
• store them separately
• keep some emergency cash separately
• keep access to my UK number and banking authentication

Losing a card should be annoying, not trip-ending. Read the full lost-card guide.

3. Assuming internet access would work the same everywhere in Asia

Thailand makes it easy to get used to Google, YouTube, messaging apps and normal Western internet access.

China reminded me very quickly that this is not universal.

This is another wider-Asia lesson, but it changed how I think about preparing for every border crossing.

What I'd do differently

I would check:

• which apps work
• how I will navigate
• how I will pay
• whether my mobile data setup works
• what I need downloaded before entry

4. Thinking distance on a map tells you journey time

A journey can look tiny on Google Maps and still become a pain because of traffic, station access, weather or the exact road layout.

What I'd do differently

I would choose accommodation based much more heavily on:

• BTS/MRT access
• the journeys I make repeatedly
• the actual walking route
• not just "X km from centre"

And for getting around, I'd think about how I'm travelling, not just where: car, motorbike taxi or train can give very different journey times for the same trip.

5. Not understanding payment systems before needing them

Thailand has QR codes everywhere.

That does not mean a British tourist can automatically use them.

Cash, cards, local QR systems and foreign banking apps overlap in slightly confusing ways.

What I'd do differently

Before arriving I would understand:

• whether my card charges foreign fees
• ATM fees
• DCC
• whether my bank can pay Thai QR codes
• how I would get cash if the card disappeared

6. Treating every travel problem as something I needed to solve in the moment

A lot of stress disappears if the backup plan already exists.

Lost card? Know the backup.

No mobile data? Offline map.

Airport transfer late at night? Know the taxi/Grab process.

Flight without Wi-Fi? Downloads already done.

The lesson is not "plan every minute".

It is pre-solve the boring failure points.

The bigger lesson

The useful travel mistakes are not "I forgot to visit Temple X".

They are systems:

• money
• connectivity
• transport
• heat
• backups

Fix those and the trip becomes much easier.
