Travel Guide — Bangkok

🌏Overview

Thais call it Krung Thep, short for a 168-letter ceremonial name — the longest city name in the world. Bangkok holds two cities on top of one another: the one of khlongs, gilded temples and riverside markets, and the one of Sukhumvit towers linked by a Skytrain running fifteen metres above the traffic. It is also the starting point for almost any trip to Thailand, southern islands included.

🏛️ Capital Bangkok

🏙️Major Cities
Bangkok
10.7 million

The old city of Rattanakosin holds the Grand Palace and the major temples; Sukhumvit and Silom hold the towers, the nightlife and the malls; Thonburi, across the river, keeps its canals.

Ayutthaya
55,000

The former capital of the Kingdom of Siam, 90 minutes by train. UNESCO-listed temple ruins, including the Buddha head held in the roots of a fig tree at Wat Mahathat.

Kanchanaburi
30,000

Two and a half hours west, the Bridge on the River Kwai and the Death Railway, built by Allied prisoners of war. War cemeteries and museums.

Pattaya
120,000

Two hours southeast, the busiest resort on the Gulf of Thailand. Beaches, dense nightlife and the carved wooden Sanctuary of Truth.

Hua Hin
85,000

Three hours south, the royal family's historic seaside resort. Quieter than Pattaya, with a night market and the Klai Kangwon Palace.

⭐Top Attractions
  1. Grand Palace and Wat Phra Kaew 🏛️ Culture

    Royal residence from 1782 to 1925 and home of the Emerald Buddha, a 66 cm jade figure whose robes the king changes himself three times a year. Strict dress code: shoulders and knees covered.

  2. Wat Pho 🏛️ Culture

    The 46-metre Reclining Buddha, covered in gold leaf, with feet inlaid in mother-of-pearl. It is also the birthplace of traditional Thai massage, still taught on site.

  3. Wat Arun 📍 Architecture

    The Temple of Dawn on the Thonburi bank, its 70-metre prang encrusted with thousands of fragments of Chinese porcelain. Best at sunset, seen from the opposite bank.

  4. Chatuchak Market 🌆 Urban

    15,000 stalls across 12 hectares, open at weekends: one of the largest markets on earth. Clothes, antiques, plants, street food. Expect to get lost — everyone does.

  5. The Chao Phraya and the khlongs 🌿 Nature

    The river is still the city's spine. The Chao Phraya Express boat serves the major temples for a few baht, and the Thonburi canals show a stilted Bangkok the modern city erased elsewhere.

☀️Weather & Seasons
🌍
Climate

Tropical monsoon climate, hot all year. Three seasons rather than four: hot, wet and cool — the last being relative, since January still reaches 32°C.

✅
Best Time to Visit

November to February: 25-32°C, drier air, clear skies. It is high season and prices follow.

⚠️
Avoid

March to May, the hot season, when the thermometer regularly passes 38°C with crushing humidity. September and October concentrate the rain and the street flooding.

Cool (Nov–Feb)
22°C to 32°C

The best window. Loy Krathong in November covers the river with floating lanterns.

Hot (Mar–May)
28°C to 40°C

Punishing. Songkran, the Thai new year in mid-April, turns the city into a three-day water fight.

Rains (Jun–Aug)
26°C to 34°C

Violent but short downpours, usually late afternoon. Fewer crowds and lower rates.

Late monsoon (Sep–Oct)
25°C to 33°C

The wettest months. Some streets turn into rivers twenty minutes into a storm.

📋Practical Info
  • 🛂
    Visa Visa exemption extended to 60 days in 2024 for most Western European, North American and Australian nationals, extendable by 30 days locally. Passport valid six months. The paper arrival card has been replaced by online registration.
  • 🔌
    Voltage 220 V, Type A, B and C sockets. Thai outlets often accept both flat and round pins, but rarely European earth pins.
  • 💧
    Eau Do not drink the tap water. Bottled water costs ฿10-15 and hotels provide it. Ice in restaurants and street stalls, however, is industrially produced and safe.
  • 💸
    Pourboire Appreciated but not expected: ฿20-50 for a waiter, rounding up for a taxi. Upscale restaurants sometimes add 10% service.
  • 💵
    Argent Cash still rules at markets, street stalls and in taxis. Cards work in malls and hotels. ATMs charge a flat ฿220 fee per withdrawal, so take out large amounts at once.
  • 🏥
    Santé No mandatory vaccinations. Bangkok has excellent private hospitals — Bumrungrad and Samitivej cater to international patients. Travel insurance is essential. Dengue is present: use repellent.
  • 🚨
    Urgences Ambulance: 1669 | Police: 191 | Tourist Police (English, 24/7): 1155
🛡️Safety
★★★★☆ Safe

Bangkok is safe for travellers: violence against foreigners is rare and busy districts are comfortable late into the night. The risk is almost entirely commercial — well-rehearsed scams aimed at new arrivals.

📍 Areas to Watch

No district needs avoiding as such. Ordinary care in the crowds of Khao San Road and the night markets. Traffic is the real hazard: crossing takes patience, and scooters filter between lanes.

⚠️ Common Scams

  • 'The Grand Palace is closed today': a helpful stranger redirects you to a gem shop or a tailor. The palace is never closed to visitors — go and check the entrance yourself
  • The ฿20 tuk-tuk city tour: the price actually buys compulsory stops at shops that pay the driver commission
  • Taxi refusing the meter and offering a flat fare: get out and take another, or book on Grab
  • Scooter rental against your passport, followed by a claim for pre-existing damage — photograph the bike from every angle before leaving

💡 Safety Tips

  • Respect for the royal family is a legal obligation: lèse-majesté is a serious criminal offence, including for something posted online
  • At temples, cover shoulders and knees, remove your shoes, and never point the soles of your feet at a Buddha image
  • Carry a copy of your passport: the original should stay at the hotel, never as a deposit with a rental shop
📱Mobile Connectivity
Network Coverage Excellent 4G/5G coverage across Bangkok, including BTS and MRT stations and tunnels. 5G is dense in Sukhumvit, Silom and Siam.
Network Quality ★★★★★
Operators AIS, DTAC, True Move H

📶 Why you'll need mobile data

  • Grab is the only reliable way to avoid taxi haggling: price shown upfront, trip recorded
  • Google Maps to navigate a system of numbered sois where number 39/2 can sit 300 metres from number 39
  • Translating street-stall menus, almost always Thai-only, with the camera translator
  • Paying by PromptPay QR code, now accepted down to market stalls
  • Following flood alerts in the rainy season, when some streets become impassable within twenty minutes

Activate your ZapSim eSIM before you fly — connected on landing at Suvarnabhumi, so you can book a Grab instead of dealing with taxi touts.

🚄Getting Around

✈️ From the Airport

Suvarnabhumi (BKK): the Airport Rail Link reaches Phaya Thai in 26 min (฿45), then connect to the BTS. Metered taxi: ฿300-400 to the centre, plus a ฿50 airport surcharge and tolls. Don Mueang (DMK), used by low-cost carriers, is served by the A1 and A2 buses to BTS Mo Chit.

🗺️ Getting Around

The BTS Skytrain and MRT cover most modern districts and skip the traffic entirely, which matters — Bangkok's congestion is severe. The Chao Phraya Express boat serves the old city temples. Grab for the rest. Tuk-tuks are an experience, not cheap transport.

📱 Essential Apps

  • Grab — the dominant ride-hailing app in Southeast Asia, also for food delivery
  • Google Maps — reliable for the BTS, MRT and river boats
  • Bangkok MRT — official map and fare calculator
💡

The Rabbit card works on the BTS, a different card on the MRT: the two networks do not share ticketing. For a few days, single tickets are simpler and avoid tying up a deposit.

💰Budget & Costs
🍜 Budget Meal ฿50-120 (street stall, market, noodle dish)
🍽️ Mid-Range Meal ฿400-900 per person
🛏️ Budget Stay ฿600-1,200 (guesthouse, budget hotel)
🏨 Mid-Range Stay ฿2,500-5,000
🎒 Backpacker Budget ฿1,200-1,800 per day
✨ Comfort Budget ฿4,000-8,000 per day

💡 Bangkok offers some of the best value for money on earth when it comes to eating: an excellent street dish costs under ฿100, roughly 3 USD. The gap with hotel restaurants is enormous, often tenfold for food that is not ten times better.

🎌Culture & Etiquette

✅ Do

  • Return the wai — palms together, slight bow — when one is offered, without initiating it towards someone younger
  • Take your shoes off before entering a temple, a home, and many small shops
  • Stand for the royal anthem, played in stations and cinemas at 8 am and 6 pm
  • Eat with the spoon, using the fork to push: chopsticks are only for noodles
  • Bargain at markets with a smile, never aggressively

❌ Don't

  • Never touch anyone's head, a child's included: it is the most sacred part of the body
  • Don't point with your foot or put your feet on a seat or table — the foot is the most impure part
  • Never criticise the royal family, even in jest: it is a criminal offence carrying prison time
  • Don't lose your temper in public: raising your voice makes everyone lose face and ends the conversation

💡 Did you know?

  • Bangkok's full ceremonial name runs to 168 letters and holds the Guinness record for the longest place name in the world
  • The city sinks about one centimetre a year under the weight of its buildings and groundwater extraction
  • Taxi colours are not decorative: red and yellow indicates a driver-owned car, other liveries a company fleet
  • There are over 400 Buddhist temples, and about half of Thai men spend a period of their life as a monk
❓Travel FAQ
How many days do I need in Bangkok?
Three full days cover the city: one for the Rattanakosin temples, one for the markets and the river, one for the modern districts. Add a day for Ayutthaya. Many travellers give it less because they are rushing on to the islands — Bangkok deserves better than a stopover.
BTS or Grab?
The BTS and MRT beat a car almost every time at rush hour: Bangkok's congestion is among the worst in Asia and a 5 km trip can take an hour. Save Grab for areas the rail network misses, for luggage, and for late nights.
Is street food safe?
Yes, and it is the best of Thai cooking. Favour stalls with a queue, where turnover is fast, and watch the food being cooked in front of you. Commercial ice is safe. The real hazard is the chilli, not the hygiene.
Do I really need mobile data in Bangkok?
Yes. Grab is the only way to avoid taxi haggling, the Thai soi numbering makes offline navigation painful, stall menus are in Thai, and mall wifi asks for a local number to receive an SMS code.
