Country guide

Thailand

Bangkok, northern culture, tropical islands and an established travel network make Thailand flexible for both first visits and slower returns.

The short version

Thailand is longer than it looks. Bangkok to Chiang Mai is a thirteen-hour overnight train, and the peninsula runs another thousand kilometres south of the capital, so a route that combines more than two or three settings turns into a sequence of transfer days. Bangkok plus the north, or Bangkok plus one coast, is a better fortnight than a circuit of both.

The lay of the land

Mountains to two coasts

Thailand runs from northern mountains through the central plain to a long peninsula with Andaman and Gulf coasts. The map looks compact until you add overnight trains, ferries and weather.

Pick a region

Three ways to split it

The north

5 to 8 days

Chiang Mai as a base for temples, hill country and khao soi, with Sukhothai a quiet detour into an older capital. Cooler, slower and mountainous.

Culture · Food · Mountains

The centre

4 to 6 days

Bangkok plus the ruined temples of Ayutthaya, an easy overland pair that anchors most routes. The rail and river hub of the whole country.

City life · History · Food

The south coast

5 to 8 days

Krabi and the Andaman islands for longtail boats and limestone cliffs, or the Gulf side when the monsoon window favours it. Pick one coast, not both.

Cost per day is a mid-range, per-person figure for a bed, food and local transport, before the bigger paid experiences. It converts to your selected currency.

What it costs

A day, by how you travel

  • Lean €2642/day Rate 2026-08-26

    Hostel dorm, street or food-court meals, local transport and mostly free sights. Islands and nightlife will push you out of this band.

  • Private and mobile €5292/day Rate 2026-08-26

    Simple private room, mixed street and sit-down meals, app rides when useful and a few paid sights or tours.

  • Comfortable €105170/day Rate 2026-08-26

    Good small hotel or apartment, restaurants most nights, frequent rides and the occasional domestic flight or boat tour averaged in. Not luxury.

Thailand stays inexpensive when you eat and move locally. Islands, alcohol, private transfers and last-minute flights change the arithmetic quickly; these figures exclude international flights.

A country-wide calendar hides two coastlines: the Andaman side is roughest during much of the southwest monsoon, while the lower Gulf is often wetter later. Treat this as a planning baseline, not a beach guarantee.

Worth routing the trip around

Signature experiences

Brick prangs and weathered towers at Wat Chaiwatthanaram in Ayutthaya
Central · 1–2 days

Walk an old capital before the buses

Ayutthaya works as a day trip, but one night gives you the cooler first and last hours. Midday is mostly heat, exposed brick and tour groups.

Rail · overnight

Take an overnight train north

A lower berth is wider and less exposed to the aisle lights. The train saves a hotel night, not time, so do not attach a tight flight connection to its arrival.

South · 3–5 days

Choose one southern coast

Longtail boats and limestone islands are straightforward; crossing the country to chase both coasts is not. Pick the side with the better weather window and leave slack for rough-sea cancellations.

Eat here

What to order, and the tell

Overhead spread of Thai dishes with curries, fried fish, herbs, lime and fresh chillies

The reliable cheap meal is usually cooked to order at a busy stall or plain shophouse. A laminated photo book beside a major attraction is normally a location surcharge, not a quality signal.

  • Pad kra pao €13 Rate 2026-08-26

    Use a cooked-to-order wok stall with a steady local queue. Add a crisp-edged fried egg; skip places where the dish is sitting pre-cooked.

  • Som tam €13 Rate 2026-08-26

    Look for a busy mortar-and-pestle stall with prices displayed. Say “mai waan” if you do not want the tourist-area version made very sweet.

  • Khao soi €23 Rate 2026-08-26

    Choose a lunch-focused shop where lime, shallot and pickled mustard greens come separately. The broth should be savoury, not mainly sugar.

  • Pad thai €13 Rate 2026-08-26

    A hot wok and condiments added at the table are better signs than bright orange noodles under a landmark-facing sign.

The essentials

Before you go

Visa and entry
Eligible passports currently receive up to 60 days visa-free at ฿0, but a shorter replacement framework has been approved and is not yet in force. A single-entry tourist visa is ฿1,000 for up to 60 days. Check MFA rules for your passport; all non-Thai arrivals must submit the free TDAC within 3 days before arrival.
Money and cards
Carry cash for stalls, small shops and local transport. Foreign-card ATM access fees are commonly ฿250 and can reach ฿350 depending on bank and card network; make fewer, larger withdrawals and decline home-currency conversion.
Getting around
Trains and long-distance buses cover the main corridors; domestic flights save time on north–south jumps. Use the official SRT D-Ticket for rail and app or metered taxis in cities.
Connectivity
Tourist SIMs and eSIMs are easy to buy, but registration with your passport is required. Buy from an operator shop or official airport counter rather than an unverified reseller.
Language
Thai is the default. English is workable in major tourist services and patchier elsewhere; save addresses, hotel names and transport details in Thai script for drivers.
Water and health
Use sealed or reliably filtered drinking water. Heat, traffic and mosquito bites cause more routine trouble than exotic scenarios; use repellent, hydrate and check current vaccine advice before departure.

Plan the shape

Routes by trip length

  1. 7–10 days

    First pass

    Keep it to the capital, one old capital and the north; adding a beach turns a short trip into a sequence of transfers.

    Bangkok · Ayutthaya · Chiang Mai

  2. 10–14 days

    North plus one coast

    Use one domestic flight to connect the north with a single beach base instead of trying to cover both southern coasts.

    Bangkok · Chiang Mai · Krabi

  3. 16–18 days

    History, jungle and coast

    Add an overland historical stop and two nights in the rainforest, then finish on one coast with enough slack for weather.

    Bangkok · Ayutthaya · Sukhothai · Chiang Mai · Khao Sok · Krabi

  4. 21–28 days

    Slow north–south

    Travel through the historic spine, use an overnight train where it helps and finish on one coast without doubling back.

    Bangkok · Kanchanaburi · Ayutthaya · Sukhothai · Chiang Mai · Khao Sok · Krabi

Read the fine print

Book with your eyes open

  • Reserve sleeper berths

    Book through SRT D-Ticket when your travel date opens. Lower berths and weekend or holiday departures disappear first; do not rely on buying the popular overnight train on arrival.

  • Pick the coast by month

    Do not lock a non-refundable island chain before checking the regional monsoon and ferry schedule. The Andaman and Gulf coasts do not fail at exactly the same time.

  • Treat Songkran as a holiday

    Around 13–15 April, transport and central accommodation tighten and street travel gets wet and slow. Book ahead or build the disruption into the plan.

  • Check the Bangkok airport code

    BKK and DMK are different airports, roughly 46 km apart. Avoid tight self-connections; the free inter-airport shuttle is only for passengers with onward-flight proof.

Two coasts

The Andaman and the Gulf do not fail at the same time

Pick the coast that suits your month instead of crossing the peninsula to see both — one good beach week beats two half-rained ones.
