Sikkim: The Complete Travel Guide (2026): Routes, Vehicles, Permits, Itineraries & Food
Sikkim is a kind of place that will test your patience before it tests your camera roll. A place that doesn’t have any railway connectivity and an airport that is so fogged up almost half the year. And for some reason, between booking your flight and actually reaching Gangtok, you will discover that India’s second-smallest state runs on a permit system left over from a 1962 dispute with China.
Please do not misunderstand them as warnings. All this is rather a cheat sheet. Once you know about these rules, such as which route actually works, which car is even allowed on which road, and what a “protected area” really means for your itinerary, Sikkim will turn from complicated into one of the easiest mountain trips in India to pull off well. This blog covers everything: how to get in, the Sikkim tourist places worth the detour, and where to eat, even if you are someone who follows a strict Jain diet.
Getting to Sikkim: The Three Ways In (and the One Everyone Gets Wrong)
Sikkim is such a destination that has no broad-gauge railway and only one working airport, so almost every route funnels through Siliguri in neighbouring West Bengal before the final climb on the map, and it burns them.
By Air: Sikkim's Nearest Airport Options
Pakyong Airport sounds like the shortcut everyone wants. Built on a ridge just outside Gangtok, it’s Sikkim's own airport. What the map doesn’t tell you is that it’s VFR (Visual Flight Rules) only, it has a very short mountain runway, and it cancels on a foggy morning more often than a flight tracker app can keep up with. Build a tight schedule around it, and you are gambling your first day of vacation on the weather. For most travellers, Bagdogra — not Pakyong — remains the nearest airport to Gangtok, Sikkim, that you can actually plan a fixed itinerary around.
Also, a note for you all: As the Bagdogra Airport is an Air Force station, there is no photography of the runway or tarmac allowed. So save your camera for the drive up, which does the scenery a better justice anyway.
By Train
If flying makes you think you'll miss the journey, the train version will give you the real rite of passage. New Jalpaiguri (NJP), near Siliguri, is the nearest railhead, about 120-125 km from Gangtok, and one of the most well-connected stations in eastern India.
NJP runs roughly 26 weekly services to/from Kolkata, 15 to Delhi, 9 to Chennai, 5 to Mumbai, and 4 to Bengaluru. Do not assume daily departure on every route, particularly if you are from the south.
By Road
National Highway 10 is the only road corridor into Sikkim, which links Siliguri to Gangtok. From Bagdogra or NJP, you have got a private taxi, a shared jeep, or an SNT bus, or, weather permitting, the Sikkim Tourism helicopter, which turns a 4-hour drive into a 20-minute hop when it is flying.
Which Route Actually Fits You
The Jeep Hierarchy of Sikkim: What You're Actually Allowed to Drive
This is one of the most crucial parts most guides skip entirely, and it is the one that actually catches you off guard: not every vehicle is allowed on every road. You show up expecting to hire a hatchback for North Sikkim, and you will be politely, firmly told no, the terrain rules it out, and the state’s own registration system enforces it.
There is also a plate to watch for: Sikkim’s tourist vehicles run on “Z-series” plates and white luxury permits, and they are the only ones allowed to move freely within the state. The cabs that you get from Bagdogra, West Bengal, or NJP stop at Gangtok’s SNT terminal. Therefore, everyone switches to or prefers a locally registered Sikkim vehicle from there, no exceptions.
