Wandiphodrang or Wangdi, in short, is another valley at an altitude of 1,300 meters in the western Bhutan about half an hour further south from Punakha a three hours’ drive (70km) southeast of Thimpu. This ancient town lies at the confluence of the Mo Chu and Tang Chu rivers. The valley is comparatively warmer than others, so the royal family of Bhutan also makes their stay at Wangdiphodrang during winter. The Wangdiphodrang Dzong is considered to be the most picturesque of all Dzongs in Bhutan.The founder of Bhutan Shabdrung Ngawang Namgyal built the Dzong in 1638 on a hilltop at the confluence of Punakha Chu and Tang Chu Rivers. The Wangdue Festival is celebrated here in the autumn. The Dzong is open for visitors during Wangduephodrang Tsechu Festival.
