Often called the “Gateway to the East,” Mongar marks a distinct change in the Bhutanese landscape. As you travel from the high-altitude central valleys of Bumthang, the road descends sharply into warmer, more tropical terrain, eventually leading you to the bustling hilltop town of Mongar.
While Bumthang is the spiritual heart, Mongar is the economic hub of the East, famous for its lemongrass, unique architecture, and rare birds.
The drive from Bumthang to Mongar is considered one of the most spectacular (and hair-raising) in the world. You will cross the Thrumshing La Pass (3,750m), where you can see the sheer drop-offs and dramatic shifts from alpine forests to subtropical jungles in just a few hours.
Mongar’s geography is quite different from the West. The town itself sits on a ridge at the elevation of 1600 m(5250 ft) but the district covers a vast range of altitudes. From as low as 200m in the southern subtropics to 4,500m at the northern mountain passes.
The Most Famous Landmarks
1. Mongar Dzong (The Modern Fortress)
Built in 1930, the Mongar Dzong is quite unique compared to the ancient fortresses of western Bhutan. While most dzongs were built in the 17th century to defend against invasions, this one was constructed under the reign of the Second King to serve as a modern administrative and religious hub for the east.
2. The Ruins of Zhongar Dzong
Before the current Mongar Dzong, the seat of power was Zhongar Dzong. Today, its massive ruins are a hauntingly beautiful site. It was once the largest fortress in the country before being destroyed by a fire and earthquake. It sits on a hilltop visible from the highway near Lingmethang.
3. Drametse Lhakhang
Founded by the granddaughter of the famous saint Pema Lingpa, this monastery is the birthplace of the Drametse Ngacham (Dance of the Drums). This sacred mask dance is so significant that it is protected by UNESCO as a masterpiece of world heritage.
4. Phrumsengla (Thrumshingla) National Park
A paradise for nature lovers, this park is home to the Red Panda, Bengal Tiger, and Snow Leopard. It is most famous among birdwatchers as the “Birding Capital of the World,” particularly the stretch through Yongkola, where you can spot the rare Satyr Tragopan and Ward’s Trogon.
Best Hike to do in Mongar
1. Aja Ney – The Sacred “Aa” Imprints
For pilgrims, Aja Ney is a bucket-list destination. It is a series of sacred caves where Guru Rinpoche meditated. It is famous for a rock where 100 imprints of the sacred syllable “Aa” are said to have appeared miraculously.
Note: Reaching Aja Ney requires a 2-day trek, making it a favorite for hikers seeking spiritual seclusion.
