Zhemgang, Bhutan
The Land of Kheng · Bhutan's Wildest Biodiversity
The Land of Kheng
Zhemgang is known locally by its older name, Kheng, and is one of the most remote and inaccessible districts in Bhutan — historically off-limits to foreign visitors and still among the least-visited today. What it lacks in tourist infrastructure it makes up for in raw biodiversity: the district spans an extraordinary elevation range, from 100 metres near the southern border to over 4,520 metres, and is home to some of the wildest, most intact forest in the country.
Much of Zhemgang sits inside protected land. The western half falls within Royal Manas National Park — Bhutan's oldest national park, established in 1966 — while the Trong area belongs to Jigme Singye Wangchuck National Park, part of the Black Mountains range. Between them, these parks shelter Bengal tigers, Asian elephants, golden langurs, and hundreds of bird species found nowhere else in the country.
Zhemgang town itself centres on a dzong with roots reaching back to the 12th century, and the district's Monpa villages — reached via the gentle, low-altitude Nabji-Korphu trek — are believed to be among Bhutan's earliest inhabitants. This is a district for travellers who want to go well beyond the standard circuit.
Must-See Places in Zhemgang
Bhutan's least-visited biodiversity hotspot, with a dzong older than the country's unification and a trek through villages few outsiders ever reach.
Zhemgang Dzong (Druk Dechen Yangtse Dzong)
Zhemgang Dzong began life in 1163 AD as a hermitage built by Lama Zhang Dorje Drakpa, a Drukpa Kagyu scholar-sage from Tibet regarded as the greatest Buddhist saint to have settled in the region. The present dzong dates to 1655, built to symbolise the unification of the three Kheng divisions — Upper, Middle, and Lower. Its most sacred room, the Goenkhang, houses a gold-plated statue of Lama Zhang that survived two fires which destroyed the rest of the structure.
Nabji-Korphu Trek
A gentle, low-altitude trek through the Black Mountains, linking the villages of Jangbi, Kubra, Nabji, Korphu, and Nyimshong — home to the Monpa, believed to be among Bhutan's earliest settlers. Run as a community tourism programme with village-maintained campsites and local guides hired stage by stage, the trek directly benefits the communities it passes through, and stays comfortably low (700m–1,650m) year-round.
Royal Manas National Park
Bhutan's oldest national park, established in 1966, spans the western half of Zhemgang district alongside parts of Sarpang and Pemagatshel. It shelters Bengal tigers, Asian elephants, golden langurs, and over 365 recorded bird species, and connects directly to India's Manas Tiger Reserve across the border — one of the most biologically significant conservation landscapes in the eastern Himalayas.
Trong Heritage Village
Facing the dzong across the valley, Trong was declared a heritage village in 2003, with restrictions in place to preserve its traditional Bhutanese architecture. It's one of the better places in Bhutan to see rural village life and vernacular building styles that have been actively protected rather than gradually modernised.
Zhemgang Tshechu
First observed in 1975, the Zhemgang Tshechu is one of Bhutan's newer festivals, held each spring at Zhemgang Dzong. Cham dances in the Drukpa Kagyu tradition are performed alongside regional Kheng folk songs and dances, closing with the unfurling of the Guru Rinpoche Thongdrel. Zhemgang receives very few international visitors, making this one of the most authentic, uncommercialised Tshechus in the country.
Getting to & Around Zhemgang
Getting There
Zhemgang is reached from Trongsa in central Bhutan, via the town of Tingtibi — roughly 105 km (about 4 hours) from Trongsa to Tingtibi alone, followed by a further climb into Zhemgang town itself. The road descends from Trongsa's highland terrain into the warmer, subtropical Mangde Chhu valley, a genuinely different landscape from central Bhutan's high passes.
Where to Stay
Accommodation in Zhemgang is very limited, reflecting how few tourists reach this remote district. Most visitors either pass through on the way to or from the Nabji-Korphu trek, where community-run campsites provide lodging along the route itself, or make a short overnight stop in Zhemgang or Tingtibi.
Weather & Best Time
March and April bring the Zhemgang Tshechu along with pleasant spring weather. November through March is the best window for the Nabji-Korphu trek, since its low elevation keeps it accessible even when Bhutan's higher trekking routes are snowed in. The summer monsoon (June–September) brings heavy rain to this subtropical district.
Wildlife & Conservation
Zhemgang's protected areas make it one of the best districts in Bhutan for serious wildlife interest, though sightings of tigers and other rare species are opportunistic rather than guaranteed. Golden langurs are more reliably spotted, and the district's bird diversity is exceptional for anyone travelling with a birding-focused itinerary.
