Located in the southwestern part of Bhutan on the Wangdue-Gelephu highway, Tsirang has gentle slopes and mild climates and is known for its rich biodiversity. One of Bhutan’s longest rivers, the Punatsang Chhu or Sankosh River flows through the district. It is the main district where the Lhotshampas (Nepali speaking Bhutanese) reside so the dominant language here is Nepali. The route from Wangdue Phodrang to Tsirang is quite scenic which offers the view of one of the largest hydro power projects in the country.
