April 19 Punakha Sightseeing After breakfast, we visit the Punakha Dzong, the “Palace of Great Happiness” built in 1647 by Shabdrung Nawang Namgyel, the Tantric saint who unified Bhutan. The Dzong lies between the Fo Chu (male river) and the Mo Chu (female river), and is the winter home of the Central Monk Body. After the Dzong, we hike to Khamsum Yuley Lhakhang, through paddy fields and past traditional farmhouses. A visit here is a good introduction to Tantric Buddhism in all its complexities.
