The grand tour, from the Golden Triangle to both coasts.
How to get around
A month lets you mix train, bus and 3 domestic flights. The only truly essential flight is the North-to-South leg (Chiang Rai → Krabi), which saves two days on the road.

Adapt by season
The grand tour ends with the Gulf (Koh Samui), which works from November to March. In the rainy season (May-October), reverse the order: do the Andaman and the Gulf while they are workable, and keep the North (dry most of the year) for the end. Avoid September-October on the Andaman, the monsoon peak.
