After breakfast, drive to Punakha Valley via Dochula Pass (3,140m). We stop at the pass to admire the 108 memorial chortens, and if the weather is clear, you will enjoy spectacular views of the Himalayan ranges.
Upon reaching Punakha Valley, visit Chimi Lhakhang, also known as the Temple of Fertility, built by Lama Drukpa Kuenley (the Divine Madman) in the 15th century. Then visit Punakha Dzong, built in 1637 by Zhabdrung Ngawang Namgyal, beautifully situated at the confluence of the Pho Chu (Male River) and Mo Chu (Female River). For many years until the reign of the second king, it served as Bhutan's capital. The construction was foretold by Guru Rinpoche, who predicted that a person named Namgyal would arrive at a hill resembling a sleeping elephant. The Zhabdrung ordered his architect, Zowe Palep, to sleep before a Buddha statue; in his dreams, the Zhabdrung took him to Zangtopelri (Paradise) and showed him Guru Rinpoche's palace. From this vision, the architect conceived the design, never committing it to paper. The Dzong was named Druk Pungthang Dechen Phodrang, meaning Palace of Great Happiness. Punakha remains the winter residence of the Chief Abbot (Je Khenpo), and King Jigme Dorji Wangchuk convened the first National Assembly here in 1952. Dinner and overnight at the hotel.
