Warm clothing - for the months of December and January, a light jacket is often necessary in the lowlands - more warm clothing may be needed if travelling in the highlands. Most towns have markets where you can buy a warm jacket for a fraction of the price you would pay at home. All Mekong countries sell sarongs of some form or another that can double as scarves, dressing gowns and towels.

People in the region dress modestly. Women visitors are not expected to wear skirts, but miniskirts and revealing shorts, may often be viewed as 'not polite'. The best plan is to dress modestly like the locals.

Footwear - bring sandals or slip ons to take off easily when entering temples. Flip flops can be bought very cheaply just about anywhere.

A small collapsible umbrella is sensible for the rainy season.

A flashlight is a good idea, in case of power cuts.
