The Dochu La (Dochu Pass, la means pass in Dzongkha) may be a mountain pass in the snow-covered Himalayas within Bhutan on the road from Thimpu to Punakha where 108 memorial chortens or stupas known as "Druk Wangyal Chortens" have been built by Ashi Dorji Wangmo Wangchuk, the eldest queen dowager. Aside from the chortens, there's a monastery called the Druk Wangyal Lhakhang (temple), inbuilt in honor of the fourth Druk Gyalpo (head of the state of Bhutan), Jigme Singye Wangchuk; the open grounds in its yard is a venue for the annual Do Chula Druk Wangyal Festival. The pass with 108 memorial chortens is adjacent to the country's first Royal Botanical Park.
