History of the Old Silk Route

The Ancient Trade Connection

The Old Silk Route of Sikkim is a branch of the legendary Silk Road — the vast network of trade routes that connected the East and West for centuries. While the main Silk Road stretched from China through Central Asia to the Mediterranean, several branch routes extended into the Indian subcontinent through the Himalayan passes.

The Sikkim branch of the Silk Route was a critical trade corridor between India and Tibet, passing through the Nathu La and Jelep La passes in East Sikkim. For centuries, this route facilitated the exchange of:

• Silk and wool from Tibet
• Rice, spices, and tobacco from India
• Precious stones, musk, and gold from both regions
• Salt (a critical commodity in the mountains)
• Horses and yaks from Tibet
• Tea, sugar, and cotton from India

Historical Timeline

The Younghusband Connection

One of the most significant historical events associated with the Old Silk Route was the British Younghusband Expedition of 1903–1904. Colonel Francis Younghusband led a British military expedition through this very route, crossing the Jelep La Pass into Tibet. The expedition ultimately reached Lhasa and forced a trade agreement on the Tibetan government. Remnants of the British military presence, including old bunkers, rest houses, and telegraph lines, can still be found along the route.

Military Significance

After the 1962 Sino-Indian War, the entire Old Silk Route area became a restricted military zone due to its proximity to the Chinese border. The Indian Army established a strong presence along the route, and the once-bustling trade corridor fell silent. For decades, this area remained closed to civilians, preserving its pristine beauty but also cutting it off from the world.

It was only in the 2010s that the Indian government began opening up portions of the Old Silk Route for tourism, allowing travelers to finally experience this extraordinary region.

Geography & Route Overview

The Old Silk Route of Sikkim traverses the East Sikkim district, winding its way from the lower foothills near Rangpo (about 800 feet altitude) to the high-altitude Nathu La Pass (14,140 feet) on the India-China border.

The Route in a Nutshell

The modern tourist circuit of the Old Silk Route typically covers the following path:

text
NJP/Siliguri → Rangpo → Rongli → Aritar → Phadamchen → Lingtam → Zuluk → Thambi View Point → Lungthung → Nathang Valley → Kupup Lake → Old Baba Mandir → (Nathu La) → Return

Altitude Profile

Understanding the altitude changes is crucial for planning and acclimatization:

Key Geographical Features

• River Valleys: The route follows the Rangpo and Rongli river valleys in the lower sections
• Sub-tropical Forests: Dense forests of sal, teak, and bamboo in the lower altitudes
• Temperate Forests: Oak, rhododendron, and magnolia forests in the mid-altitudes
• Alpine Meadows: Open grasslands and scrublands above the tree line
• High-altitude Desert: Barren, moon-like landscapes near Nathang Valley
• Mountain Passes: Nathu La and Jelep La — historic crossing points to Tibet

Major Destinations on the Old Silk Route

Let's explore each major destination on the Old Silk Route in detail, following the natural progression of the route from lower to higher altitudes.

1. Rangpo — The Gateway to Sikkim

Altitude: ~800 feet | Distance from NJP: 75 km

Rangpo is the entry point into Sikkim from West Bengal. This bustling border town sits on the banks of the Teesta River and is where travelers obtain their Inner Line Permits (ILP) if they haven't already done so online.

Key Points:

• Rangpo Bridge Check Post: All vehicles entering Sikkim are checked here
• ILP counter available for immediate permit processing
• Last major town before heading into the Silk Route
• Basic amenities — restaurants, ATMs, fuel stations
• Confluence of Teesta and Rangpo rivers

Travel Tip: If entering Sikkim for the first time, keep your photo ID ready and carry passport-sized photos for the ILP. The process takes 15–30 minutes.

2. Rongli — The Last Town Before the Mountains

Altitude: ~2,600 feet | Distance from Rangpo: 45 km | Distance from NJP: 120 km

Rongli is the last proper town on the route before the road begins climbing into the mountains. It serves as the permit checkpoint for the Old Silk Route and the place where your documents will be verified.

Key Points:

• Permit Verification Point: Your Protected Area Permit will be checked here
• Last place with ATMs and fuel stations on the route
• Good restaurants serving Indian, Chinese, and local food
• Market for last-minute supplies
• Starting point of the climb towards the Silk Route

What to Do:

• Stock up on cash, fuel, snacks, and water
• Verify your permits at the checkpoint
• Have lunch if you're starting early from NJP/Gangtok

Important: There are NO ATMs, fuel stations, or medical facilities beyond Rongli until you return. Stock up on everything you need here.

3. Aritar (Lampokhari) — The Emerald Lake Village

Altitude: ~4,600 feet | Distance from Rongli: 30 km

Aritar is one of the most charming stops on the Old Silk Route and serves as an excellent first-night halt for acclimatization. The village is famous for Lampokhari Lake — a stunning natural lake surrounded by pine forests.

Key Attractions:

Lampokhari Lake

• A beautiful heart-shaped natural lake surrounded by ancient trees
• Pedal boating available on the lake

Accommodation: Several homestays, cottages, and budget hotels with lake or mountain views.

Pro Tip: Spend your first night at Aritar for proper acclimatization. The altitude is moderate (4,600 feet) and allows your body to adjust before climbing to 10,000+ feet.

4. Phadamchen — The Terraced Village

Altitude: ~5,500 feet | Distance from Aritar: 20 km

Phadamchen is a small village nestled in the mountains, known for its beautiful terraced farmlands and panoramic views. While most travelers pass through quickly, the village rewards those who stop and look around.

Key Highlights:

• Cherry Blossoms: Beautiful cherry trees bloom in November–December
• Valley Views: Stunning views of the deep river valley below

5. Lingtam — The Orange Village

Altitude: ~6,500 feet | Distance from Phadamchen: 12 km

Lingtam is another beautiful village on the Silk Route, famous for its orange orchards and cardamom plantations. The village offers some of the best homestay experiences on the entire route.

6. Zuluk — The Crown Jewel of the Silk Route

Altitude: ~10,000 feet | Distance from Lingtam: 15 km

Zuluk (also spelled Dzuluk) is the most famous and photographed destination on the Old Silk Route. This tiny hamlet is perched at 10,000 feet and is renowned for its iconic 32 hairpin bends that zigzag up the mountain, creating one of the most visually stunning road formations in the world.

Key Attractions:

The 32 Hairpin Bends (Zigzag Roads)

• The most iconic image of the Old Silk Route
• Best viewed from Thambi View Point above Zuluk
• The zigzag pattern of the road against the mountainside is an extraordinary engineering feat
• Looks surreal at sunrise when bathed in golden light

Thambi View Point

• Located above Zuluk at approximately 11,200 feet
• Offers a bird's-eye view of the 32 hairpin bends
• Kanchenjunga sunrise is the highlight — the entire eastern Himalayan range glows in shades of gold, orange, and pink
• Wake up at 4:30 AM to catch the sunrise (worth every second of lost sleep)

Zuluk Village

• A charming mountain hamlet with traditional wooden houses
• Small monasteries and prayer wheels
• Friendly locals who are accustomed to (but not overwhelmed by) tourists
• Military history — the Indian Army has a significant presence

Old Silk Route Museum

• A small but informative museum detailing the history of the Silk Route
• Artifacts, photographs, and maps from the trading era
• Information about the Younghusband Expedition

Accommodation: Homestays and basic guest houses. Expect simple rooms, heavy blankets, and home-cooked meals.

What to Expect:

• No electricity for extended periods — power cuts are common
• No mobile network (BSNL may work intermittently)
• No restaurants or shops — homestays provide all meals
• Extremely cold at night — even in summer, temperatures can drop below 5°C
• Clear sky nights offer spectacular stargazing

Must-Do: The sunrise at Thambi View Point is the single most unforgettable experience on the entire Old Silk Route. Don't miss it under any circumstances.

7. Lungthung — The Valley of Winds

Altitude: ~12,000 feet | Distance from Zuluk: 10 km

Lungthung is a small settlement above Zuluk that offers even more dramatic views of the Himalayan panorama. The name roughly translates to "valley of winds" — and for good reason. The wind at this altitude can be fierce and biting.

Key Highlights:

• 360-Degree Mountain Views: One of the best panoramic viewpoints in all of Sikkim
• Kanchenjunga Close-Up: The mountain feels incredibly close from Lungthung
• Sunrise Viewing: An alternative (and often less crowded) sunrise spot compared to Thambi

Accommodation: Very limited — a couple of basic homestays. Most visitors stay in Zuluk and visit Lungthung as a day trip.

Health Alert: At 12,000 feet, altitude sickness becomes a real possibility. If you experience headaches, nausea, or dizziness, descend immediately.

8. Nathang Valley (Gnathang) — The Ladakh of the East

Altitude: ~13,500 feet | Distance from Zuluk: 15 km

Nathang Valley is one of the most dramatic and surprising landscapes on the Old Silk Route. Often called the "Ladakh of the East", this high-altitude valley features a stark, barren terrain that looks nothing like the lush green Sikkim you might expect.

Key Attractions:

The Barren Landscape

• Wide-open, treeless terrain with sparse grass and rocky outcrops
• Feels like a different planet compared to the forests below
• Reminiscent of Ladakh, Spiti, or even the Mongolian steppe

Old Baba Mandir

• A temple dedicated to Baba Harbhajan Singh, a soldier of the 23 Punjab Regiment
• According to legend, Baba appeared in a fellow soldier's dream after his death in 1968, requesting that a shrine be built in his honor
• The Indian Army maintains the temple and treats Baba as a "saint soldier" who still guards the border
• His bed is made every day, and a place is set for him at meals
• A deeply moving experience regardless of your religious beliefs

Kupup Lake (Elephant Lake)

• A stunning high-altitude lake at 13,066 feet
• Called "Elephant Lake" because its shape resembles an elephant when seen from above
• Sacred to local communities
• The turquoise-green waters against the barren backdrop are incredibly photogenic
• Kupup was the site of the world's highest golf course — now defunct but historically interesting

War Memorial

• Memorials dedicated to Indian soldiers who fought in the 1962 and 1967 conflicts with China
• A sobering reminder of the region's military significance

Nathu La (Optional/Restricted)

• The famous India-China border crossing at 14,140 feet
• Open to Indian nationals only with special permits
• Typically visited on a separate day trip from Gangtok (not always accessible from the Silk Route side)
• Offers a glimpse of the Chinese border post on the other side

Accommodation: Very limited in Nathang. A few basic army-assisted accommodations and minimal homestays. Most travelers stay in Zuluk and visit Nathang Valley as a day trip.

Pro Tip: Nathang Valley is the highest point most tourists reach on the Old Silk Route. Spend minimal time here if you feel unwell due to altitude. Carry warm layers, sunscreen, and plenty of water.

9. Other Notable Stops

Health & Safety Tips

Altitude Sickness (Acute Mountain Sickness - AMS)

This is the most significant health concern on the Old Silk Route. As you climb from near sea level to 13,500+ feet in a short time, your body may struggle to adjust to the reduced oxygen levels.

Symptoms of AMS:

• Mild: Headache, dizziness, fatigue, loss of appetite, nausea, difficulty sleeping
• Moderate: Severe headache, vomiting, breathlessness, confusion
• Severe (HAPE/HACE): Fluid in lungs, swelling of brain — medical emergency

Prevention:

1. Acclimatize gradually — don't rush to high altitudes
2. Stay a night at Aritar (4,600 feet) before climbing to Zuluk (10,000 feet)
3. Stay hydrated — drink 3-4 liters of water daily
4. Avoid alcohol completely during the trip
5. Eat light, carbohydrate-rich meals
6. Avoid strenuous activity on the first day at high altitude
7. Diamox (250mg, taken 24 hours before ascending) — consult your doctor
8. Garlic soup/tea — a traditional remedy believed to help with acclimatization

What to Do if Symptoms Appear:

• Mild symptoms: Rest, hydrate, take paracetamol. Do not ascend further.
• Moderate symptoms: Descend immediately to a lower altitude.
• Severe symptoms: Emergency evacuation required — inform your guide/driver immediately.

Road Safety

• Trust your experienced local driver — they know these roads intimately
• Wear seatbelts at all times
• If you feel motion sickness, sit in the front seat and look at the horizon
• Carry motion sickness medication (Avomine/Gravinate)
• Roads can be extremely narrow with steep drops — this is normal on mountain roads
• Don't panic during difficult stretches — local drivers navigate them daily

Cold Weather Safety

• Hypothermia is a risk at higher altitudes, especially at night
• Dress in multiple layers rather than one thick layer
• Keep your head, hands, and feet covered
• If you feel extremely cold, shivering, or drowsy, warm up immediately
• Hot water bottles provided by homestays are your best friend at night

General Safety

• Travel in groups or with a reliable tour operator
• Inform someone about your itinerary and expected return dates
• Carry a printed list of emergency contacts
• The nearest hospital is in Rongli or Gangtok — there are no medical facilities on the route
• Indian Army has a presence throughout the route and can assist in emergencies

Photography Guide

The Old Silk Route is a photographer's paradise. Here are tips to capture the best shots:

Best Photography Spots

Camera Gear Recommendations

• DSLR/Mirrorless with wide-angle lens (16-35mm) for landscapes
• Telephoto lens (70-200mm or 100-400mm) for mountain close-ups
• Tripod — essential for sunrise shots and low-light photography
• Extra batteries (at least 3-4) — cold drains batteries rapidly
• Extra memory cards — you'll shoot thousands of photos
• UV filter — protects lens and reduces haze at altitude
• Polarizing filter — enhances blue skies and reduces glare
• Weatherproof camera bag
• Lens cleaning cloth — dust and moisture are constant companions

Smartphone Photography Tips

• Download a good camera app (like ProCam or VSCO) for manual control
• Use HDR mode for high-contrast mountain scenes
• Panorama mode is perfect for the 32 hairpin bends
• Time-lapse of clouds moving over mountains creates stunning videos
• Keep your phone warm (inside your jacket pocket) — cold kills battery life

Photography Etiquette

• Ask permission before photographing local people, especially monks
• Do not photograph military installations, army camps, or border areas — this is strictly prohibited and can lead to serious consequences
• Respect sacred sites — some monasteries restrict photography inside
• Leave no trace — don't disturb the environment for the sake of a photo

Flora & Fauna

The Old Silk Route passes through multiple ecological zones, from subtropical forests to alpine meadows, creating an incredibly diverse range of plant and animal life.

Flora

Special Mention: Rhododendrons

Sikkim is home to 36 species of rhododendrons, and the Old Silk Route passes through some of the best rhododendron forests. During March–April, the hillsides transform into a riot of red, pink, white, and purple blooms — a truly spectacular sight.
