Approximately the size of Switzerland, with a breathtaking landscape of thick forests, patchwork paddy fields, rugged mountains and lush valleys dotted with centuries-old dzongs (fortress monasteries) and rural villages, Bhutan may be small, but there's a lot to see. Stretching from the high Himalayas in its far north, through the steep foothills in its centre to the plains of India in the south, this magnificent country offers a wealth of geographical and cultural riches.
