Perched on the rugged ridges of East Sikkim, Zuluk (9,400 ft) once served as an indispensable overnight horse-staging outpost on the ancient Silk Route connecting Lhasa in Tibet to the trading markets of Bengal. Today, it beckons intrepid travelers with its dramatic 32 switchback curves climbing toward Thambi Viewpoint, tranquil high-altitude lakes, and genuine Himalayan homestay hospitality.
Before modern borders were defined, traders, Tibetan monks, and British explorers traversed the treacherous Jelep La pass with mule caravans laden with raw Tibetan wool, silk, musk, gold dust, and tea. Zuluk was the primary village where horse caravans halted after crossing the windswept frontier.
Traveling this route today is like stepping into living history. The remote high-altitude landscape retains its quiet, untouched mountain rhythm, free from the commercial crowds found in larger hill stations.
The crowning highlight of any Silk Route journey is navigating the jaw-dropping 32 zigzag loops ascending from Zuluk to Thambi Viewpoint at 11,200 ft. Engineered along an almost vertical ridge, the road resembles a winding ribbon coiling into the clouds.
Setting out before dawn (05:00 AM) brings you to Thambi Viewpoint just as the first golden rays of sunrise illuminate the jagged summit of Mount Kanchenjunga (8,586 m). Looking downward, the complete geometry of the 32 loops is unveiled through swirling morning mists—a sight revered by landscape photographers across the globe.
Ascending further beyond Thambi Viewpoint brings you into the high-altitude frontier above 12,000 ft:
1. Lungthung (12,500 ft): A scenic ridge offering panoramic 360-degree vistas across both the Sikkim and Bhutan mountain frontiers.
2. Gnathang Valley (12,700 ft): Often called the Ladakh of East Sikkim, this windswept glacial valley was the historic encampment of the British-Tibet War of 1888.
3. Kupup Lake (13,066 ft): Affectionately named Elephant Lake because its natural contours mirror an Asian elephant, complete with a trunk and tail. Nearby sits the Yak Golf Course, certified by the Guinness Book of Records as the highest 18-hole golf course on Earth.
4. Old Baba Mandir (13,100 ft): The original bunker shrine dedicated to Indian Army hero Major Harbhajan Singh at the base of Jelep La pass.
The entire Silk Route corridor is governed by military security protocols. Permits are issued at the Sub-Divisional Police Office (SDPO) in Rongli:
1. Required Documents: Original Indian Voter ID Card or Valid Indian Passport + 2 passport-size photographs per person. Aadhaar Cards and PAN Cards are not accepted at Lingtam or Padamchen checkposts.
2. Foreign Nationals: Foreign citizens, including tourists from Nepal and Bhutan, are strictly restricted from the Silk Route zone east of Rongli.
3. Checkpost Gate Hours: The Rongli checkpost permits entry between 08:30 AM and 02:00 PM. Travelers should depart early to avoid gate closures.
There are no luxury 5-star hotels in Zuluk or Gnathang Valley. Accommodations are community-run Sikkimese homestays operated by warm, hospitable local families.
Rooms are clad in aromatic pine wood and furnished with heavy quilts, electric heating blankets, and attached western bathrooms with hot water provided via geysers or bucket service. Meals are fresh, organic, and home-cooked, featuring steaming local dal, seasonal saag, farm eggs, chicken curry, and traditional buckwheat rotis.
