From bustling markets to prayer flag-strewn mountain passes, from happy monks in maroon robes to massive ancient fortresses, Bhutan is a Shangri La for image-makers. In the month of June the summer landscape takes on a luscious green with rice paddy fields covering all of Paro Valley, wild flowers strewn like dots of paint on the alpine meadows. In November the monsoon clouds are a distant memory and the landscape snap s into sharp focus with crystal light, inky skies and fabulous mountain views.
