What to know first

You can look up flights to all three from Incheon and Busan (Gimhae) on the route pages below. Straight-line distances from Incheon are about 3,380 km to Chiang Mai, 3,670 km to Bangkok (Suvarnabhumi) and 4,320 km to Phuket. Check schedules and flight times with the airlines (check official) and recent fares on the route pages.

They feel very different: Bangkok is a big city of temples, food and shopping; Phuket is a beach and island-hopping escape; Chiang Mai is a relaxed northern city of temples, mountains and cafes. All three are generally most pleasant around November to February.

Bangkok — temples, street food and shopping

The Grand Palace and Emerald Buddha, the Reclining Buddha and the Temple of Dawn across the river, plus weekend markets, Chinatown street food and giant malls.

The Airport Rail Link reaches the city from Suvarnabhumi in about 25-30 minutes, avoiding traffic. In town, the BTS and MRT and the river boats make getting around easy.

Best season: November-February is the cool, dry season. March-May is very hot, and June-October brings short, heavy afternoon downpours.

Best for: first trips to Thailand or abroad, food and shopping lovers, friends and families.

Phuket — the Andaman Sea and island trips

Thailand's largest island ranges from lively beaches to quiet family beaches and a colorful Old Town, and it is the gateway to Phi Phi and Phang Nga Bay boat trips.

The airport is in the north, about 45-60 minutes from Patong, so decide which beach to stay on first.

Best season: November-April brings calm, clear seas. In the May-October rainy season, big waves on the west coast mean swimming is banned on some days and tours can be cancelled. December-January is peak season with the highest prices.

Best for: travelers after beaches and island trips, and families or couples wanting a resort stay.

Chiang Mai — temples, mountains and slow travel

The old capital of the Lanna kingdom, with a moated Old City full of temples. Hilltop temples, national parks, night markets, cooking classes and cafes keep many travelers here for longer.

The airport is just south-west of the Old City, about 15-20 minutes away. If you visit elephants, choose a sanctuary-style place with no riding and no shows.

Best season: November-February is cool and dry. March-April is very hot, and smoke from surrounding forest fires can make the air quality very poor. May-October is rainy but green.

Best for: travelers who prefer a slower pace, lovers of temples, nature and cafes, and long stays.

Side by side

Plan at least three or four nights in each, and four or five for Phuket.

Use ride-hailing apps with fixed fares or official taxi counters for airport and city rides
Island trips may be cancelled in the rainy season — leave slack in your plans
Cover shoulders and knees when visiting temples
In Chiang Mai around February-April, check the air quality index, and bring a mask or change dates if you have breathing problems
