In most of mainland Southeast Asia, it's now moving into the 'cool' season, which means high season in terms of visitors and prices, but it is still the most agreeable time to see the mainland countries without suffering too much from the heat.
The boxes below will give you an idea of which destinations are at their best now, as well as some places you should start planning for if your travel is later in the year. I've tried to select a mix of popular destinations along with some off-the-beaten-path places where you can escape the crowds and soak up some culture or sun.
The impressive ancient capital of the Khmer empire.
Phuket's Old Town area makes a pleasant getaway from the beach for an afternoon.
Samui (January to September)
An idyllic and mostly deserted beach on the southern tip of Samui.
Charming old Lao capital.
Thailand / Songkran (April)
Some people take Songkran very seriously.
Sukhothai (November to March)
The ancient remains of the first 'Thai' kingdom.
A stunning landscape and beach in Krabi province, southern Thailand.
The rock-cut graves of Tana Toraja
One of Kuching's many monuments to its cats.
Thailand is still the major destination in mainland Southeast Asia, but there is so much more to see, and some of it is quite accessible. Many people have their sights set on seeing the splendors of Angkor at least once, but why not spend more time in Cambodia, taking in the bustling capital of Phnom Penh and the lazy coastal area of Kampot?
For the more adventurous, there are the rivers, ancient monuments and 4,000 islands of Southern Laos. Or, if Thailand is still your thing, why not get a little off the beaten path in a place like Sukhothai.
