Thailand welcomed over 28 million international visitors in 2024, and the Tourism Authority of Thailand acknowledges that scam awareness is a top concern for travelers, with the Grand Palace tuk-tuk scam, jet ski damage scam, and gem store tricks being reported by thousands of tourists annually on forums and embassy advisories. This guide covers every major scam operating in Thailand, where they happen, and how to avoid losing your money.
Thailand is one of the safest countries in Southeast Asia for tourists, and violent crime against visitors is extremely rare. The risks are almost exclusively financial: scams, overcharging, and petty theft. Knowing the playbook in advance makes you nearly immune to all of them.
The Grand Palace “Closed” Scam (Bangkok)
This is Thailand’s most famous tourist scam and it operates every single day outside the Grand Palace on Na Phra Lan Road. Here is how it works:
As you approach the Grand Palace entrance, a well-dressed Thai person (sometimes wearing an official-looking lanyard) approaches and tells you the palace is closed today for a special Buddhist ceremony, a royal event, or a public holiday. They seem genuinely concerned for you and suggest a “better” temple nearby. They flag down a tuk-tuk driver who offers an unbelievably cheap fare (20-50 baht) for a tour of several temples.
The tuk-tuk takes you to one or two lesser temples, then stops at a gem shop, a tailor, or a “Thai government export center.” The driver earns commission for every tourist who enters these shops, where you will be aggressively pressured to buy overpriced gems or suits. Some travelers have lost thousands of dollars buying “investment grade” gems that turn out to be worth a fraction of the price paid.
How to avoid it:
- The Grand Palace is open daily from 8:30 AM to 3:30 PM (last entry). Walk past anyone who says it is closed.
- Enter only through the official Visitoratorn Gate on Na Phra Lan Road
- Never accept a tour from someone outside an attraction
- If a tuk-tuk ride seems too cheap (under 100 baht for a long route), there is a commission scheme behind it
The Jet Ski Damage Scam (Phuket, Koh Samui, Pattaya)
This scam is most common in Phuket (Patong Beach), Koh Samui (Chaweng Beach), and Pattaya. You rent a jet ski for 30-60 minutes, and when you return it, the operator discovers “damage” — a scratch, a dent, or a cracked hull that was there before you rented it.
They demand 10,000 to 50,000 baht (roughly $280 to $1,400 USD) for repairs. If you refuse, they threaten to call the police, and in some cases, associates appear and become physically intimidating. Some operators hold your passport as security during the rental, giving them leverage.
Protection steps:
- Take video of the jet ski from every angle before and after renting
- Never hand over your passport. Offer a photocopy or a cash deposit instead
- Keep your passport in a neck wallet worn under your shirt so it is not easily accessible to hand over impulsively
- Consider skipping jet ski rentals entirely in high-scam areas
Gem and Jewelry Store Scams (Bangkok)
The gem scam has been running in Bangkok since the 1980s and remains active. You are told by a friendly local that the Thai government is having a special jewelry sale (one day only) at a specific store. Or a tuk-tuk driver takes you there as part of a “free” tour.
At the store, you are shown beautiful gems at prices that seem like incredible deals. They provide certificates of authenticity and promise the gems can be resold at home for double the price. The gems are real but massively overpriced — a stone sold for $2,000 may be worth $50-100. The certificates are from non-accredited labs.
The Australian, British, and American embassies in Bangkok all publish specific warnings about this scam on their travel advisory pages.
Khao San Road: The Backpacker Gauntlet
Khao San Road in Banglamphu is Bangkok’s legendary backpacker strip. While it is a vibrant, fun area, several scams target the young, budget-conscious travelers who congregate here:
- Fake travel agencies: Storefront “agencies” sell bus, train, and flight tickets that are either counterfeit or heavily marked up. Book through official channels or reputable platforms like 12Go Asia.
- Spiked drinks: Rare but reported. Never accept drinks from strangers and watch your drink being poured.
- Motorbike rental damage claims: Similar to the jet ski scam. Photograph the bike thoroughly before renting.
- Bag snatching: Motorbike riders grab bags from pedestrians. Wear a crossbody bag or neck wallet that cannot be easily snatched.
Taxi and Tuk-Tuk Overcharging
Bangkok taxis have meters with a flag fall of 35 baht. Many drivers refuse to use the meter, especially for trips from tourist areas to airports or between popular zones. The most common issues:
- Meter refusal: Driver offers a flat rate of 300-500 baht for a trip that should cost 80-150 on the meter
- “Broken” meter: The meter mysteriously does not work, but only for tourist passengers
- Long routing: Taking expressways or longer routes to inflate the metered fare
- Airport taxi mafia: Unofficial drivers at Suvarnabhumi and Don Mueang airports charging 2-3x the meter fare
Solution: Use the Grab ride-hailing app for transparent, fixed pricing. For airport transfers, use the official taxi stand on the first floor of Suvarnabhumi (Level 1) and insist on the meter plus the 50-baht airport surcharge.
ATM and Money Safety in Thailand
Thai ATMs charge a 220-baht ($6+ USD) foreign transaction fee per withdrawal. Some ATMs offer “conversion” to your home currency at terrible exchange rates — always choose to be charged in Thai baht.
ATM skimming has been reported at standalone ATMs in tourist areas. Use ATMs attached to bank branches, preferably inside the bank during business hours. Keep your primary cards in RFID-blocking sleeves and only carry one withdrawal card in your wallet.

Frequently Asked Questions
What is the Grand Palace closed scam in Bangkok?
A friendly local outside the Grand Palace tells you it is closed for a ceremony or holiday. They offer to take you to a ‘better temple’ instead, routing you through gem shops and overpriced tailors where they earn commission. The Grand Palace is open daily 8:30 AM to 3:30 PM except during actual royal ceremonies.
Are tuk-tuks in Bangkok safe?
Tuk-tuks are generally safe for your personal security, but many drivers will quote inflated prices or take you to commission-earning shops. Always agree on a price before getting in and refuse detour offers. An Alpha Keeper neck wallet keeps your cash hidden so you can pull out only the exact fare.
What is the jet ski scam in Thailand?
After you return a rented jet ski, the operator claims you caused damage (often pre-existing) and demands hundreds of dollars in repair costs. They may threaten to call police or hold your passport. Photograph the jet ski from every angle before and after renting.
Is Khao San Road safe?
Khao San Road is safe from violent crime but common issues include overpriced drinks, fake taxi meters, drug scams, and bag snatching by motorbike riders. Keep valuables in an Alpha Keeper neck wallet, not your pockets.
Should I carry my passport in Thailand?
Thai law requires foreigners to carry their passport, but most police accept a clear photocopy. Keep the original in your hotel safe and carry a copy in a money belt or neck wallet.
What are the common taxi scams in Bangkok?
Drivers refusing to use the meter (flag fall is 35 baht), claiming the meter is broken, taking longer routes, and demanding flat rates are all common. Use the Grab ride-hailing app for transparent pricing. Check out our White RFID Sleeve Set. Check out our Colorful RFID Sleeve Set.
