In the heart of Southeast Asia, the kingdom of Thailand encompasses a rich diversity of cultures and traditions shaped by more than 2,000 years of Buddhism. The landscape too is hugely varied, with the mountains and forests of the north contrasting with the vast rice fields of the central plains and the beautiful tropical islands and long coastline of the peninsula in the south. THailand's superb scenery, tropical climate and renowned hospitality (it's also known as the "Land of the Smile"), not to mention its unique cultural heritage, attracts millions of visitors annually.
