Frequently asked questions

What can I do in 20 days?

Either see all of Thailand at a relaxed pace, from Kanchanaburi to the islands, or combine Thailand with one or two neighbours such as Cambodia, Laos or Vietnam.

How are border crossings handled?

By short regional flights or overland, for example via Chiang Khong–Huay Xai into Laos. Transfers are arranged; check entry requirements for your nationality before you travel.

When is the best time for a long trip?

November to February is favourable across most of the region. Northern Vietnam is cool in winter and central Vietnam wettest from October to December.

Can I add beach days?

Yes: you can add a few nights in Phuket, Krabi or Koh Samui at the end, all linked to Bangkok by short flights.
