The Taktsang Palphug Monastery (also known as Tiger’s Nest) is said to be the holiest side in Bhutan, where Guru Rinpoche materialized 1,300 years ago on the back of a flying tigress, meditated for three years, then converted the Bhutanese to Buddhism. It is located in the cliffs 3000 feet above the Paro Valley, and 10,000 feet above sea level. It’s only accessible via mountainous paths, but is well worth the climb for the gorgeous views along the way, and once you arrive.
