How to Reach Sikkim

The Practical Route Guide from Every Indian City

Last Updated: July 2026

Summary: Fly into Bagdogra Airport (IXB) near Siliguri, then take a taxi 124 km up NH10 to Gangtok, about 4 to 5 hours. The nearest railhead is New Jalpaiguri (NJP), roughly the same drive. Sikkim has no working airport or railway of its own yet. Indian tourists need no permit to enter.

The last time the monsoon caught me on this road, we sat below Melli for three hours while a JCB pushed a slab of hillside off the tarmac, and I ate two plates of chilli-hot momos from a tin-roof stall because there was nothing else to do. So, this is not a copy-paste list of distances. It is what actually works, what to book ahead, and the mistakes that cost people a full day.

The one thing to understand before you plan a Sikkim trip.

Sikkim is a small Himalayan state wedged between Nepal, Bhutan, Tibet and West Bengal. It does not have a working commercial airport, and the railway line is still being built. Everything funnels through two points in North Bengal: Bagdogra Airport and New Jalpaiguri railway station , both near Siliguri and only about 15 km apart. Whichever city you start from, your real question is only “how do I get to Bagdogra or NJP”, and then “how do I cover the last stretch to Gangtok or wherever I am staying”.

Get that fixed and the rest is simple.

How to Reach Sikkim by Air

Bagdogra is the airport you actually want

Bagdogra Airport (IXB), just outside Siliguri, is the main airport for all of Sikkim and Darjeeling. It is well connected, with daily direct flights from Delhi, Mumbai, Kolkata, Bengaluru, Chennai, Hyderabad, Ahmedabad and more, flown by IndiGo, Air India Express, Akasa Air, SpiceJet and Air India. From Bagdogra, Gangtok is about 124 km and a 4-to-5-hour drive.

Book a shared or private taxi from the pre-paid counter outside the terminal, or arrange a pickup in advance. In peak season (April to June, and October) the taxi queue after a midday flight can be long, so an arranged cab saves you standing in the sun with your bags.

Budget for the cab, because this is where people get caught out. A seat in a shared jeep from Siliguri or Bagdogra to Gangtok runs roughly Rs 350 to 500 per person, and a full reserved taxi is about Rs 3,000 to 4,000 depending on car and season (both to confirm at the time, fares move with fuel and demand). The shared jeep is fine if you travel light. With bags and family, reserve the car.

What about Pakyong Airport?

Sikkim does have its own airport at Pakyong, about 30 km from Gangtok, opened in 2018 and is located on a ridge at around 4,500 feet. It looks perfect on paper. In practice, commercial flights have been suspended since June 2024 and, as of mid-2026, no scheduled airline is flying there. Low passenger numbers and weather cancellations (the runway needs clear visibility) kept it from becoming reliable. Airlines have announced restarts more than once without following through.

So do not plan your trip around flying into Pakyong. Check its status close to your travel date, but assume Bagdogra until proven otherwise. I have watched travellers book a Pakyong “flight” through a lookalike search result and end up scrambling.

The helicopter shortcut

If you want to skip the road entirely, the Sikkim Tourism Development Corporation runs a helicopter between Bagdogra and Gangtok . It takes roughly 30 minutes instead of 4 to 5 hours, and the one-way fare was cut to about Rs 3,100 per passenger in late 2025 (to confirm at booking, as fares change). Free baggage is limited to around 7 kg per person, with charges above that.

Two honest cautions. First, it is a small aircraft and it flies only in good weather, so cancellations happen, especially in the monsoon. Second, seats are limited and it does not run through the day, so treat it as a bonus, not a guaranteed plan. Keep a road option in reserve.

How to Reach Sikkim by Train

The nearest major railhead is New Jalpaiguri (NJP) , one of the busiest junctions in the northeast, with well over a hundred trains a day. From NJP to Gangtok is about 125 km and the same 4-to-5-hour drive as from Bagdogra. Siliguri Junction is a little closer at around 113 km but has far fewer long-distance trains, so most people use NJP.

Outside the station you will find pre-paid taxis and shared jeeps to Gangtok and Siliguri. Shared jeeps are cheap and frequent, private taxis are quicker and cleaner.

Is there a train to Sikkim itself?

Not yet, but it is coming. The Sivok to Rangpo railway line will be Sikkim’s first-ever rail link, running about 45 km from Sivok in West Bengal to Rangpo on the Sikkim border. As of 2025 to 2026 it had crossed 70 percent of physical work, and the official target for completion is December 2027. When it opens, you will be able to take a train much closer to Sikkim than NJP. For now, plan around New Jalpaiguri.

How to Reach Sikkim by Road

If you enjoy driving in the hills, the classic approach is NH10 from Siliguri to Gangtok , running alongside the Teesta River. The Teesta runs jade-green below the road for most of the way, past Teesta Bazaar and the Coronation Bridge at Sevoke, and after rain the air turns to wet pine and diesel. Somewhere past Rangpo your ears pop as the road climbs. On a good day it is a smooth 4 to 5 hours.

What you need to know : NH10 is landslide-prone, particularly in the monsoon (June to September). Fresh slides near Sevoke, Chitrey and Selfie Dara have shut the road for hours at a stretch in recent seasons. When that happens, traffic is diverted onto longer alternate routes such as the Gorubathan road or the Coronation Bridge, Mongpong and Gajoldoba corridor, which can add two to three hours. If you are travelling in the rains, keep a buffer day and do not book a same-day connecting flight home.

Self-driving from far-off cities is possible but rarely worth it. The value of your own car ends at Rangpo, because inside Sikkim the roads, permits and mountain driving are best left to local drivers who know the state. Most visitors fly or train to North Bengal and hire a Sikkim-registered taxi from there.

City by City: How to Reach Sikkim from Where You Live

For every city below, the destination is the same: reach Bagdogra or NJP, then drive up. What changes is how you get there.

From Delhi

The simplest option is a direct flight from Delhi to Bagdogra , about 2 hours to 2 hours 20 minutes, flown by several airlines daily. By train, direct services run from Delhi to New Jalpaiguri, but it is a long haul of well over a day, so most Delhi travellers fly. Fly to Bagdogra in the morning and you can be in Gangtok by evening.

From Mumbai

Mumbai has direct flights to Bagdogra, though frequency is lower than from Delhi, so book early. Many fares route through Kolkata or Delhi, which is fine if the total time and price suit you. Trains from Mumbai to NJP exist but run close to two days, so flying is the sensible call.

From Kolkata

Kolkata is the gateway city for the whole region and your easiest starting point. Frequent short flights (a little over an hour) go to Bagdogra all day. The overnight train from Kolkata to NJP is a genuinely good option too, roughly 8 to 10 hours over about 500 km, so you sleep on the train and start the drive up in the morning. Of all Indian cities, Kolkata gives you the most choices.

From Pune

Pune has limited direct air links to Bagdogra, so expect to connect through Mumbai, Delhi or Kolkata. Check for the occasional nonstop, but plan on a one-stop flight. Once you land at Bagdogra, the route is the same as everyone else’s.

From Hyderabad

IndiGo and others run direct Hyderabad to Bagdogra flights , which makes this an easy trip of roughly 3 hours. That single nonstop saves you a painful multi-day train. From Bagdogra, drive up to Gangtok the same day if you land by early afternoon.

From Bengaluru

Bengaluru has direct flights to Bagdogra (Air India Express and others), around 3 hours in the air. The train is not realistic here, the fastest Bengaluru to NJP service runs close to 40 hours, so fly. A morning departure gets you to Gangtok comfortably by nightfall.

From Chennai

Chennai to Bagdogra is served by direct flights of about 3 hours. Trains from Chennai to NJP exist but cover more than 2,000 km over two days, so unless you love long rail journeys, take the flight and enjoy an extra day in the hills instead.

From Kochi

Kochi is the farthest of these cities, and there is usually no direct flight to Bagdogra. Plan to connect through Bengaluru, Chennai, Delhi or Kolkata. Yes, it is a longer travel day, but a single well-timed connection still gets you to Bagdogra by evening, ready to drive up the next morning.

From Ahmedabad

Akasa Air and others offer direct Ahmedabad to Bagdogra flights, which is a pleasant surprise for a route people assume needs a stop. Where no nonstop suits your dates, connect via Delhi or Mumbai. From Bagdogra, the drive to Gangtok is unchanged.

Getting from Bagdogra or NJP into Sikkim

This last leg trips up more people than the flights do, so plan it properly.

Your choices are:

a private taxi (fastest and most comfortable, and it lets you stop where the Teesta runs jade-green below the road, near Teesta Bazaar and the Coronation Bridge at Sevoke, for photos and a tea),

a shared jeep from the Siliguri or NJP stands (cheapest, but it leaves when full and drops you at a common point), or

the helicopter to Gangtok if weather and seats allow. Sikkim Nationalised Transport also runs buses, which are inexpensive but slow.

Whatever you pick, aim to leave the plains by early afternoon. The hill roads are far less pleasant after dark, and a landslide delay in the monsoon is much easier to absorb with daylight in hand.

One rule I give everyone: on your way home, do not book an evening flight out of Bagdogra for the same day you leave Gangtok. If NH10 slips even once, you miss it. Come down a day early, or take a morning flight and keep the afternoon as a cushion.

Permits: what you actually need to enter Sikkim

Good news for Indian travellers. You do not need any permit to enter Sikkim or to visit Gangtok, Pelling, Ravangla, Namchi or the popular towns. You simply show a government photo ID at the Rangpo check post and carry on. Keep a few passport photos and original ID (Passport, Voter ID (EPIC), or Driving License) + copies handy anyway, because you will need them for the special-area permits.

Permits come into play only for the protected and border areas: Nathula Pass, Tsomgo (Changu) Lake, Baba Mandir, and all of North Sikkim (Lachung, Lachen, Yumthang, Gurudongmar). These need a Protected Area Permit, which your registered Sikkim tour operator arranges for you, usually a day ahead, using your ID and photos. You cannot get most of these on your own, which is exactly why booking through a local tour operator in Sikkim matters.

Foreign nationals need a Restricted Area Permit to be in Sikkim at all. It is free, valid for 30 days, and can be obtained at the Rangpo check post, Bagdogra airport, or the Sikkim House offices in Kolkata and Siliguri, among other points. Foreigners have some area restrictions (Nathula and Gurudongmar are off-limits to them, for instance), so foreign visitors especially should plan permits with a local agency. Permit rules do change, so confirm the current position before you travel.

Best time to arrive, and when the journey gets harder

The road matters as much as the destination when you decide when to go. March to May brings clear mountain views and blooming rhododendrons, and the drive up is usually trouble-free. October and November are my personal favourite, crisp air, clean skies and the most reliable roads of the year. The monsoon, June to September, is when NH10 turns temperamental, so it is beautiful and green but you must build in buffer days. December to February is cold and quiet, with the chance of snow closing the highest passes, though the main route to Gangtok stays open.

Why plan your Sikkim trip with Sikkimtourism.org

This is where a local team earns its keep. SikkimTourism.org is a Sikkim-based operator, and is run from Sikkim, by people who drive these roads in every season. When NH10 shuts near Sevoke, we know within the hour and reroute your car before you are stuck for half a day. We arrange your Bagdogra or NJP pickup, hold Sikkim-registered drivers who actually know the Teesta Road, and handle the Protected Area Permits for Nathula, Tsomgo and North Sikkim so you are not chasing paperwork on your holiday.

Our honeymoon and Sikkim family packages are quoted without flights or train fare, which keeps them transparent, and if you would like help booking your flights or rail tickets to reach Bagdogra or NJP, our team can assist with that too. Ground knowledge, local relationships and real familiarity with Sikkim’s routes, permits and weather are the whole point, and that is what we bring.

Frequently Asked Questions

Which is the nearest airport to Sikkim?

Bagdogra Airport (IXB) near Siliguri is the nearest functional airport, about 124 km and 4 to 5 hours by road from Gangtok. Sikkim’s own Pakyong Airport has had no scheduled commercial flights since June 2024, so plan for Bagdogra.

Which is the nearest railway station to Sikkim?

New Jalpaiguri (NJP) is the nearest major railhead, roughly 125 km and a 4-to-5-hour drive from Gangtok. Sikkim has no railway station yet, but the Sivok to Rangpo line is under construction and targeted for December 2027.

Do I need a permit to visit Sikkim?

Indian tourists need no permit to enter Sikkim or visit Gangtok and most towns, just a photo ID at Rangpo. You do need a Protected Area Permit for Nathula, Tsomgo Lake and North Sikkim, which a local operator arranges. Foreign nationals need a free Restricted Area Permit.

How do I reach Gangtok from Bagdogra Airport?

Take a private taxi or shared jeep for the 124 km, 4 to 5 hour drive up NH10, or fly the STDC helicopter for a roughly 30-minute hop when weather and seats allow. Book a taxi in advance during peak season to skip the airport queue.

How long is the drive from Siliguri or NJP to Gangtok?

About 4 to 5 hours in normal conditions along NH10 beside the Teesta River. Allow extra time in the monsoon, when landslides can divert traffic onto longer routes and add two to three hours.

Is there a helicopter service to Gangtok?

Yes. The Sikkim Tourism Development Corporation flies between Bagdogra and Gangtok in about 30 minutes, with a one-way fare around Rs 3,100 as of late 2025 (confirm at booking). It runs only in good weather and has limited seats, so keep a road backup.

When is the best time to travel to Sikkim?

March to May and October to November give the clearest skies and the most reliable roads. The monsoon (June to September) is green but landslide-prone on NH10, so build in a buffer day if you travel then.
