When you first land in Bangkok, your senses are flooded: humid air, the sizzle of street-food woks, tuk-tuk horns echoing down alleys, neon signs reflecting off puddles. But behind that alluring facade lies another Bangkok—one full of grit, frustration, and hard tradeoffs. This article navigates the bad things about Bangkok with the eye of someone who walks its sidewalks daily. Expect stories, sharp critique, and tips so you can enjoy this city while dodging the pitfalls.
I’ll walk you through nine key negatives you should know—smog, traffic, scams, heat, noise, inequality, infrastructure risk, nuisance wildlife, and bureaucratic friction. And yes, I’ll also give you strategies so these don’t wreck your trip.
1. Choking Smog & Air Pollution
If Bangkok has a seasonal villain, it’s the smog, especially during late dry season (January–March). In 2025, Bangkok was blanketed with hazardous PM2.5 levels multiple times, prompting school closures and urging residents to stay indoors.
Walking around Sukhumvit or Silom during a bad day, you can taste the pollution—your throat itches, your eyes sting, and the city’s silhouette blurs into gray. For visitors, it’s more than irritation—it can trigger asthma attacks, allergies, or discomfort for anyone sensitive.
Traveler tip:
- Monitor air quality (apps like AirVisual).
- Choose hotel rooms on higher floors with air purifiers.
- Plan outdoor activities early morning (before smog builds) or after rain.
2. Gridlocked Traffic (and Tuk-tuk overcharges)
Bangkok’s traffic is notorious—and with good reason. Even a 5-km ride in mid-day can take 30–45 minutes. In monsoon rains, roads flood, and power cuts at intersections worsen the bedlam.
I once hopped on a tuk-tuk near Victory Monument at 5 p.m., hoping to beat rush hour. After ten minutes, we had barely moved. The driver aggressively insisted we take a “shortcut” (a narrow soi) and demanded double fare at the end. I learned the hard way to always insist “meter only” (มิเตอร์) first.
Tips:
- Use BTS/MRT where possible — they skip road congestion.
- For taxis, insist on using the meter and take a photo of the license plate before departing.
- Avoid journeying during 17:00–19:30 if possible.
3. Scams, Dual Pricing & Hidden Extras
As a local I’ve watched too many tourists get tricked. Some common pitfalls:
- Temple “closed” scam: A tuk-tuk driver will tell you Wat Pho is closed, take you elsewhere, and demand extra.
- Dual pricing: Some attractions charge different rates for Thais vs. foreigners.
- Fake guides or side-trip fees: Someone “volunteering” to be your guide may demand a tip or take you to overpriced shops.
In 2025, Thailand’s tourism has overall slowed, partly due to reputational concerns about scams and perceptions of safety.
How to stay safe:
- Use trusted tour agencies.
- Always check entrance fees online in advance.
- Be skeptical of unsolicited help (especially at piers or train stations).
4. Sweltering Heat & Humidity
Bangkok is not kind to bodies unused to tropical intensity. The heat is pervasive—walking alleys in Chinatown, your shirt clings to your skin; waiting in a motley queue under neon lamps feels like standing in an oven.
Even tourists who relish “tropical climate” often misjudge: anytime above 35 °C with >80% humidity feels punishing.
Survival strategies:
- Dress light, breathable fabrics, and carry a refillable water bottle.
- Use shade, umbrellas, early morning or late evening for walking tours.
- Plan indoor or air-conditioned spots in your schedule (museums, malls, cafes).
5. Noise, Crowds & Sensory Overload
Bangkok is loud. Late at night, streetfood vendors rev up generators, tuk-tuks bleep, karaoke blares in back-street venues. In densely packed districts (Khao San, Sukhumvit soi), it’s nearly impossible to rest peacefully unless your hotel is well insulated.
Crowds amplify this. In peak tourist spots like Grand Palace, Chatuchak, Wat Arun riverside, you jostle with umbrellas, selfie sticks, loud group tours. The charm can slip into chaos.
Advice:
- Choose hotels tucked in quieter sois or backstreets.
- Bring earplugs or white noise apps.
- Hit major sites early (before 8:30 a.m.) or late afternoon.
6. Visible Inequality & Urban Frictions
Bangkok is a city of contrast. Luxury malls (Siam Paragon, EmQuartier) stand beside cramped alleys. High-rise condominiums look over informal settlements, concrete canals, and derelict buildings.
Walking through Lat Phrao or Bang Na, you’ll see food vendors, scooters piled with cargo, and locals struggling with rising costs. It’s a reminder: being a tourist in Bangkok means viewing snapshots of daily hardship.
As an insider, I feel a moral obligation to support local businesses (street vendors, small eateries) rather than just global brands.
7. Infrastructure Risks & Construction Hazards
Bangkok’s infrastructure is under constant strain. In 2025, an under-construction building near Chatuchak collapsed in the wake of tremors triggered by a Myanmar earthquake.
More recently, a road collapse (sinkhole) opened on Samsen Road in Dusit district, damaging the roadway and prompting evacuations near Vajira Hospital.
While these events are rare, they underscore the fragility that can accompany rapid urban growth and heavy construction. Also, flooding during the rainy season can disrupt transit and inundate lower floors.
Precautions:
- Stay alert for blocked roads or diverted transit.
- Avoid staying in ground-floor guesthouses in low-lying areas.
- Follow local news (Bangkok Post, BMA alerts) when heavy rain hits.
8. Wild Neighbors: Monitor Lizards & More
You may have seen funny social media posts about “Bangkok Godzillas” — giant monitor lizards (Varanus salvator) creeping along canals, parks, or even sewers. In 2025, their population in urban areas like Lumphini Park surged.
Most are harmless if ignored. But one place I got spooked: walking late in a quiet soi near my house, I heard rustling. Turned out to be a 1.5-meter lizard slithering away. That said, locals mostly coexist, but it can rattle the nerves for visitors.
Also, you’ll find rats (especially in older markets), stray dogs, and at times insects swarming streetlights.
Tips:
- Avoid walking too close to canal edges.
- Don’t feed or provoke wildlife.
- Be cautious around trash or wet alleys at night.
9. Bureaucracy, Visa Hassles & Permission Woes
Bangkok’s bureaucracy tends to move slowly. If you want to extend visas, get permits, or do any administrative task, expect queues, paperwork, and sometimes unpredictable answers.
I once accompanied a traveler to Immigration at Chaeng Wattana to extend a tourist visa. The forms changed mid-day, and one official demanded a printout of something blank. We waited 3 hours.
Tourist rule changes (visa holidays, length limits, overstay fines) can also shift suddenly. Always check the Thai Immigration website or embassy sources before you travel.
Putting It All Together
Yes, Bangkok dazzles. But behind the sparkle are friction points—some manageable, others that test your patience. Use this guide not to scare you but to arm you. With these in your toolkit, you can enjoy the city’s magic without being undone by its flaws.

Conclusion
Bangkok is intoxicating — and imperfect. The smog that stings your nose, the horn-blaring crossings, the hidden tax in a tuk-tuk—all these are part of the mosaic.
