Often regarded as one of the wildest and least developed nations in South East Asia, Laos's charm lies in the very fact that it remains a largely unchanged nation with natural landscapes and a rich culture bereft of Western ideals and conglomerates. Landlocked by Thailand and Cambodia, this last frontier is made up of four thousand islands. Some of the key highlights on a tour of Laos include a trip to the Luang Prabang historic city. As the former capital of the country, the UNESCO World Heritage Site is lined with breathtaking temples and other edifices. Zip lining fanatics will also find Laos the perfect holiday destination while ecotourism enthusiasts should head down to Vang Vieng to try their hand at kayaking, hot air ballooning and caving adventures.
