Nathula pass and Tsomgo Lake – An Overview
Nathula Pass
Nathula is a mountain pass in Sikkim bordering China’s Tibet Autonomous Region, and it’s been the site of real historical conflict — most notably a military standoff in 1967. Today it’s a heavily guarded but popular tourist spot, visited as a day trip from Gangtok. It’s the corridor connecting Sikkim to Tibet, so it’s a high-security zone: you can only drive to the base of the Nathu La border area, and from there you walk up a flight of stairs to the actual border line. Photography is strictly prohibited at the border itself — more on that below.
Tsomgo Lake
In East Sikkim sits Tsomgo Lake, also called Changu Lake by locals — a glacial lake at roughly 3,753 m (12,400 ft). It’s fed by melting snow from the surrounding peaks, considered sacred by local Buddhist and Hindu communities, and freezes over in winter. In summer, wildflowers bloom around its edges instead.
How to plan the Tsomgo Lake and Nathula Pass day trip from Gangtok?
Nathula Pass is roughly 56–60 km from Gangtok and takes about 1.5–2 hours to reach by road. Tsomgo Lake sits on the same route, closer to Gangtok, and local guides almost universally recommend visiting Nathula first, Tsomgo Lake on the way back. The reason: Nathula sits at a much higher altitude and its weather is unpredictable — it can turn from clear to snowing within an hour. Get the higher, weather-sensitive stop done early, then unwind at Tsomgo Lake on the descent.
The drive itself is one of the highlights — scenic mountains, remote East Sikkim villages, and (if you’re lucky with weather) uninterrupted Himalayan views the whole way. So, below are the details on how to plan Tsomgo Lake and Nathula Pass day trip from Gangtok.
Prepare for the trip to Nathula Pass and Tsomgo Lake
Permits
Nathula Pass sits on a live international border, so both Tsomgo Lake/Baba Mandir and Nathula Pass require permits. Your travel agent or cab operator arranges these for you — you don’t need to visit a government office yourself. Budget around ₹200 per person for the permit fee (this can vary, so confirm current pricing with your operator).
Important: Only Indian nationals are eligible for the Nathula Pass permit. If you’re travelling on a foreign passport — including OCI or PIO cardholders — you won’t be able to go beyond Tsomgo Lake. Worth checking before you build your itinerary around Nathula specifically.
Cab Options
You have two options for the day:
| Option | Approx. Cost | Best for |
|---|---|---|
| Shared cab | ~₹1,000 per person | Budget travelers, solo trips, don’t mind a crowd |
| Private cab | ~₹3,000–4,000 total | Privacy, flexible timing, couples/families |
If you want to go at your own pace and skip waiting on other passengers, a private cab is worth the extra spend. Just know that even in a private cab, you’ll be transferred into a shared cab for the final stretch to Nathula itself (see below) — that part’s non-negotiable for security reasons. Read my road trip essentials list while planning for Tsomgo Lake and Nathula Pass day trip.
The route from Gangtok to Nathula Pass
The drive winds through snow-capped mountains and genuinely postcard-worthy lakes. The roads are surprisingly well-maintained — a pleasant surprise if you’ve done rougher Himalayan drives, like the road trips through Himachal Pradesh.
How to reach Nathula Pass
How it works, step by step: If you start from Gangtok in a private cab, your guide drives you past Tsomgo Lake first. A short distance beyond the Tsomgo Lake viewpoint is a checkpoint — the “connection point” — where everyone, private cab or not, is transferred into a shared cab for the final leg to Nathula. This is purely a security protocol for the high-altitude border zone.
Quick Tsomgo Lake Viewpoint Pitstop
Quick Tsomgo Lake viewpoint pitstop: At this checkpoint, guides recommend renting warm clothes and snow boots if you haven’t brought your own — you’ll need them at Nathula. It was already cold here, so we grabbed coffee and Maggi noodles while we waited. I wore just a sweater and the guide smirked, telling me it wouldn’t be enough. He was right — rent the extra layers here if you’re unsure.
Don’t worry – you will be visiting Tsomgo Lake when coming back. There’s a reason for this – Nathula is at a much higher altitude and the weather here is unpredictable. It is recommended that you reach there as early as possible.
We started quite early – around 8 AM – from Gangtok to increase our chances to visit Nathula before the weather gets bad.
What to do in Nathula Pass
The shared cab drops you at the base location, from where you walk a short stretch on the main road before reaching a staircase leading up to the actual border. It’s usually snowy and can be slippery — I saw a few people slip who weren’t being careful.
We were extremely careful, walking up the stairs slowly and not cutting lines. Cutting lines really won’t help you, since you’ll not have any rope to hold and it’ll be easy to fall. At the risk of sounding arrogant, I would suggest please follow the queue, you’ll have enough time. But keep yourself & others’ safety in mind.
Photography
Nathula Pass sits directly across from a Chinese army post, so photography is not permitted at the border itself. Ignoring this can get you an earful from the Indian Army stationed there. You’re free to take photos once you’re back down from the actual border line.
Head back to Tsomgo Lake
Since you arrive at Nathula in a shared cab, you’ll wait for the rest of the group before heading back. We used the wait to take in the landscape — genuinely magical — until it started snowing.
Guides and army personnel started moving people back to their cabs quickly once the snow picked up, since heavy snowfall can block the road entirely. It snowed heavily the whole way down — my first ever snowfall, and I loved every second of it.
Back at the Tsomgo Lake connection point, we switched into our private cab again — a relief after the more cramped shared ride.
Tsomgo Lake on the way back
Tsomgo Lake is one of the most popular glacial lakes in Sikkim and remains frozen in the winter, in summer flowers bloom around the lake. There are numerous things to do in Tsomgo Lake from a small trek around the lake, Yak Safari or simply enjoying the scenery of the lake surrounded by the snow mountains.
When we reached here, it was still snowing, so the trek was out of the question. We enjoyed some time here, walked around and started our journey back to Gangtok.
If you only want to visit Tsomgo Lake and skip Nathula entirely (say, if you’re not eligible for the Nathula permit, or just short on time), it’s easily doable as a shorter trip — Tsomgo Lake alone is about 37–40 km from Gangtok.
There’s no real food scene at these altitudes since the areas are remote, but basic hot food tastes incredible in the cold. We waited for a proper meal until we got back to Gangtok.
Before heading back, we returned our rented warm clothes and boots — and came home with a memory card full of snow.
What to pack for Tsomgo Lake and Nathula Pass
At 3,753 m and 4,310 m respectively, both stops are cold even in summer. I packed only a sweater for my Sikkim trip, which was a mistake — I ended up renting a warmer jacket at the Tsomgo Lake base camp. Here’s what I’d actually recommend:
- Jeans or fleece-lined pants
- A warm sweater as a base layer
- A thick, insulated winter jacket
- Gloves – winter waterproof gloves are ideal
- Leg warmers like these and these.
- Warm socks
- Boots — flat soles only, no heels (rentable at base camp if needed)
- A Sling bag for women, avoid heavy bags as they can be difficult to carry when you have to focus on snow & not slip while going up to Nathula Pass.
