Tadlo - on the Bolaven Plateau in Southern Laos: beautifully pastoral, gorgeous waterfalls, cute children, and a five-day party (Pi Mai Lao!)

Don Khon - one of the Four Thousand Islands in the Mekong between Laos and Cambodi (Don Khon is on the Laos side - the smallest/quietest of the three with tourist facilities): unbelievably gorgeous, quiet paths to wander, French colonial ruins to climb, and a buff-cheeked gibbon to play with...

Or - if you've got time to kill - see all the picture sets!
