This is a full day of exploration through the lush Punakha Valley, which at 1,200m is low enough for bananas and oranges to grow. The morning starts with a short walk across farmhouses and rice paddies to Chimmi Lhakhang, a 15th-century fertility temple dedicated to Drukpa Kuenley, a Tibetan Buddhist saint, better known as the ‘Divine Madman’. This site has long been a pilgrimage for couples hoping to start a family. Heading further down the valley, the 300-year-old Punakha Dzong comes into view. Built in the 17th century by Zhabdrung Ngawang Namgyal (who founded the Kingdom of Bhutan), the fortress once housed the country’s government. It is now the winter home of Je Khenpo, the head abbot of Bhutan, along with a retinue of 1,000 monks. After lunch, the tour takes you on a walk through homesteads and farmland to Khamsum Yulley Namgyal Chorten, a shrine recently built by the royal family.
