Shuanghu

Shuanghu, located in Shuanghu County of the Nagqu Prefecture, is the highest county-level administrative district in China, with an average elevation of approximately 4,900 meters. The name “Shuanghu” (meaning “Twin Lakes”) derives from two adjacent highland lakes—Kangmu Ru Lake and Rejiao Lake—situated near the county seat. Positioned at the very edge of the Changtang uninhabited zone, Shuanghu represents the final frontier between human civilization and extreme wilderness. The county covers an enormous area of approximately 120,000 square kilometers (roughly the size of Zhejiang Province), yet sustains a permanent population of barely over 10,000, making it one of the least densely populated regions in China.

The most significant natural attraction within Shuanghu is the Purog Kangri Glacier, the largest glacier mass on Earth outside of the polar regions, covering approximately 422 square kilometers. The glacier surface features spectacular ice towers, ice caves, and crevasses that refract an ethereal blue glow under sunlight, creating an extraordinarily dramatic visual spectacle. Additionally, Shuanghu County contains numerous highland lakes and vast stretches of desert steppe. It serves as one of the most critical habitats for rare wildlife including Tibetan antelopes (chiru), Tibetan wild asses (kiang), and wild yaks, earning the area the reputation as a “paradise for wild animals.”

Shuanghu County is located in the northwestern part of Nagqu Prefecture, approximately 560 kilometers from Nagqu city and about 900 kilometers from Lhasa. From Lhasa, the typical route proceeds north along the G109 National Highway to Nagqu, then westward along the G317 National Highway or local roads through Bangge County and Nyima County toward Shuanghu. The total journey requires approximately 2 to 3 days of driving, with overnight stops recommended in Nagqu and either Bangge or Nyima.

Road conditions to Shuanghu are generally challenging. The Nagqu-to-Bangge section follows a paved national highway in reasonable condition, while portions of the Bangge-to-Shuanghu section consist of dirt roads and basic surfaces that may become muddy or waterlogged during the rainy season. A reliable four-wheel-drive vehicle operated by an experienced driver is strongly recommended throughout. Shuanghu county town offers a small number of guesthouses and restaurants providing basic accommodation and meals under relatively simple conditions. The Purog Kangri Glacier is located approximately 90 kilometers from the county seat, requiring separate vehicle arrangements to visit.
