Thrumshing La, also called Thrumshingla Pass and Donga Pass, (Dzongkha: ཁྲུམས་ཤིང་ལ་; Wylie: khrums-shing la; "Thrumshing Pass"), is the second-highest mountain pass in Bhutan, connecting its central and eastern regions across the otherwise impregnable Donga range that has separated populations for centuries. It is located on a bend of the Lateral Road at the border of Bumthang District (Ura Gewog, leaving Ura southbound) and Mongar District (Saling Gewog, toward Sengor), along the border with Lhuntse District to the east. The Lateral Road bisects Thrumshingla National Park, named after the pass. The World Wildlife Fund also maintains operations in the park.
