Getting to Kupup/Elephant Lake Isn’t Easy—But That’s the Fun
Perched at 12,800 feet near the India-China border, Kupup/Elephant Lake (also called Elephant Lake) isn’t your casual day-trip destination. The journey involves military checkpoints, dizzying mountain roads, and possibly yaks blocking your path. Here’s how to tackle it like a pro.

Step 1: Get to Gangtok (Your Launchpad)
All Kupup journeys start in Sikkim’s capital.
- By Air: Bagdogra Airport (125km away) is the closest. Pre-book a taxi (₹2,500-3,000) for the 4-hour drive to Gangtok.
- By Train: New Jalpaiguri (NJP) station has overnight trains from Kolkata/Delhi. Shared jeeps to Gangtok cost ₹300/person.
- By Road: Private cars from Darjeeling (100km) take 5 hours—NH10 has brutal but scenic twists.

Pro Tip: Arrive in Gangtok a day early—permits take time.
Step 2: Secure Your Permits
Kupup sits in a restricted border zone. Here’s the paperwork drill:
- Indians: Need Protected Area Permit (PAP) from Gangtok’s DC office or registered tour operators.
- Foreigners: Not allowed (except Bhutanese with special clearance).
- Secret Hack: Book a Nathu La day tour—many agents add Kupup as an “unofficial” extension.
Warning: Apply before 10 AM—permits run out fast in peak season (May-Nov).
Step 3: The Make-or-Break Drive
Only authorized jeeps (no private cars) can go beyond Tsomgo Lake. Here’s what to expect:
- Gangtok to Kupup: 75km (4-5 hours) via Nathu La route
- Terrain: Potholed roads, sudden landslides, and zero guardrails
- Key Stops:
- Tsomgo Lake (15,400ft): Stretch your legs, sip butter tea
- Baba Harbhajan Singh Mandir: Soldiers swear the “ghost” protects travelers
- Zuluk Loops: 32 hairpin bends where brakes scream for mercy
Altitude Trick: Chew gum to pop ears during climbs.
Step 4: Survive the Last Stretch
Past Nathu La, the real test begins:
- Army Checkpoint #1: Show permits, surrender cameras with zoom lenses
- The “Dead Zone”: 18km of moonscape roads with China visible left, India right
- Final Hurdle: A 1km hike from parking to the lake (thin air burns lungs)
Pro Move: Rent oxygen cans (₹500) at the last checkpoint—trust us, you’ll need them.
When to Go (And When to Bail)
- Best Months: May-Jun & Sep-Oct (clear skies, passable roads)
- Months to Avoid:
- Jul-Aug: Landslides turn routes to sludge
- Dec-Apr: Snow buries everything (army closes access)
Local Secret: October mornings sometimes reveal PLA soldiers building snowmen on their side.
What Most Guides Won’t Tell You
- Toilets? A lone army latrine exists—bring toilet paper and courage.
- Food: Only the military canteen serves edible noodles (don’t ask about the meat).
- Phone Signal: Dead zone. Tell family you’ll “resurface” in Gangtok.
Why Bother? The Kupup Magic
Standing beside that eerie, elephant-shaped lake at 12,800ft, with Chinese bunkers staring back—it’s the closest you’ll get to a real-life spy thriller. The bragging rights alone are worth every bump on the road.
Final Tip: Wear waterproof boots. The lake’s edges look solid until you sink knee-deep in glacial mud.
