Check the details before booking. To Bangkok, you fly out from Gatwick and return to Heathrow, with about 14 hours in Guangzhou on the way back. To Chiang Mai, the stop in Beijing is about 12 hours on the way out, and the return also lands at Heathrow. Phuket has the shortest stops, in Beijing and Chengdu.


💰 How far does your money go?

A pint in London now costs £6-7. In Thailand, a cold Chang from a 7-Eleven is about £1.20, a bowl of khao soi in Chiang Mai around £1.50 and a plate of pad thai from a Bangkok street stall £1.50. A Thai massage costs about £7 an hour.


☀️ The Weather

December to February is the cool, dry season and the best time to visit. Bangkok has highs of 32°C and very little rain. Chiang Mai is fresher, with 29°C by day and 14-15°C at night. Phuket has calm seas and highs of 32°C.


🏨 Where to Stay

One stay for each stop.

Once Again Hostel (Bangkok) · 9.3/10 · From £18/night

Tamarind Village (Chiang Mai) · 9.1/10 · From £93/night

🎯 What to Do

Three cities, three very different sides of Thailand.

Wat Arun at sunset, Bangkok: Cross the river by ferry for the best view of the Temple of Dawn as the lights come on.

Doi Suthep, Chiang Mai: The golden temple on the mountain above the city, reached by a 300-step staircase.

Elephant Nature Park, Chiang Mai: An ethical sanctuary where you watch the elephants instead of riding them.

Phang Nga Bay, Phuket: Limestone towers rising out of the sea, best explored by kayak.


🗺️ Where to Go From Here

Once you are in Thailand, flights between the three cities are short and cheap.

Bangkok to Chiang Mai: About 1h10 by air, or an overnight sleeper train. Search flights

Bangkok to Phuket: About 1h20 by air. Search flights

Krabi and Koh Phi Phi: Limestone cliffs and islands, about 2 hours from Phuket by ferry.

Pai: A laid-back mountain town, about 3 hours by road from Chiang Mai.


From £346 return to Thailand, with a checked bag included. Pick your city, or do all three.
