Luang Prabang One of the most charming cities in south-east Asia, Luang Prabang is the most popular tourist attraction in Laos. Until 1975, when the communist took over the country, it was the royal capital of Laos. The main part of Luang Prabang is located on a peninsula between the Nam Khan and Mekong rivers. A collection of golden-roofed temples, wooden houses and crumbling French provincial buildings fill the main roads. At dawn, monks from the various monasteries walk through the streets collecting alms of rice.
