Rangpo is Sikkim's main entry town, at roughly 300–350 m where the Rangpo Chu meets the Teesta on the West Bengal border. NH10 crosses here, foreign travellers have their permits checked, and the Sivok–Rangpo railway is being built to end here. Parts of the town were badly hit by the October 2023 Teesta flood. Check current status before you travel.
The local story
A river border, a highway and a railway
At Rangpo a small river, the Rangpo Chu, comes down from the hills of East Sikkim and joins the Teesta, and that meeting point marks the boundary between West Bengal and Sikkim. For most of the twentieth century the road up the Teesta valley from Siliguri was the main way into the kingdom, and later the state, of Sikkim. The bridge at Rangpo became its front door: a checkpost, a police post, and around them a town of shops, workshops, transport offices and lodges serving the trucks and jeeps that keep Gangtok supplied.
Two events have shaped Rangpo's recent years. The first is the railway. The Sivok–Rangpo line, about 45 km long and running mostly through tunnels along the Teesta gorge, is meant to bring trains into Sikkim for the first time, with Rangpo as its terminus. Work has gone on for years and target dates have slipped more than once. The second is the flood. On the night of 3–4 October 2023 a glacial lake outburst from South Lhonak Lake in North Sikkim sent a surge down the Teesta that breached the Chungthang dam and swept through the valley. In Rangpo, low-lying areas near the river were flooded and buried in silt, and NH10 was cut in several places.
At Rangpo the Rangpo Chu joins the Teesta, and the small river marks the West Bengal–Sikkim boundary on NH10, Sikkim's main road link with Siliguri.
The Sivok–Rangpo railway, about 45 km long and mostly in tunnels, is planned to be Sikkim's first rail link, with Rangpo as its terminus; completion dates have slipped repeatedly.
On the night of 3–4 October 2023, a glacial lake outburst from South Lhonak Lake sent a flood down the Teesta that damaged low-lying Rangpo and cut NH10 in several places.
About Rangpo
Almost everyone who travels to Gangtok by road passes through Rangpo, and almost nobody stops for long. It is a hot, low river town at roughly 300–350 m, busy with trucks, shared jeeps and checkpost queues, and its job is to let people and goods into Sikkim. For travellers it matters for three practical reasons: the checkpost, where foreign nationals have their Restricted Area Permit checked or issued; the shared jeep links to Gangtok, Pakyong, Rongli and Siliguri; and the state of NH10 on either side.
That road has been fragile since the October 2023 Teesta flood. Stretches of NH10 between Sevoke, Melli and Rangpo have been washed away or blocked by landslides many times since, and closures can last days or weeks. When NH10 is shut, traffic between Siliguri and Sikkim detours through Kalimpong, Pedong and Rhenock, or via Lava and Algarah. The Sivok–Rangpo railway, when it opens, should ease this; it was still under construction at the time of writing. Check current status before you travel.
What to see and do
The Sikkim checkpost
Rangpo is the main road entry to Sikkim. Foreign nationals must show or obtain a Restricted Area Permit here, and vehicles and passengers may be checked. Indian travellers do not need a permit to enter Sikkim, but should carry photo ID. Check current status before you travel.
The Teesta and Rangpo Chu confluence
Where the Rangpo Chu meets the Teesta, the border between West Bengal and Sikkim runs down the smaller river. Since the October 2023 flood the riverbanks have changed shape, with wide silt flats and damaged buildings still visible in places.
The Sivok–Rangpo railway
Sikkim's first railway, about 45 km from Sivok, is being built to end at Rangpo, with most of the line in tunnels along the Teesta. Construction has run for years and opening dates keep moving. Check current status before you travel.
A practical lunch stop
Highway eateries in Rangpo feed truckers, jeep drivers and travellers all day: rice thalis, momos, chowmein and tea. Prices are local, and it is a sensible place to eat if a checkpost queue or road block holds you up.
Junction for Pakyong, Rongli and Aritar
From Rangpo a road climbs up the Rangpo Chu valley to Rorathang, then on to Rongli for the Silk Route, Aritar and Rhenock, or up to Pakyong. Travellers coming from Siliguri can head for the Silk Route without going to Gangtok first.
How to get there
Shared jeep or bus from Siliguri
Shared jeeps and SNT buses bound for Gangtok pass through Rangpo, about 75 km and 2.5–3.5 hours from Siliguri when NH10 is open. A seat to Rangpo costs about ₹200–300. NH10 has had repeated, long closures since October 2023. Check current status before you travel.
Shared jeep from Gangtok
Shared jeeps run from Gangtok to Rangpo and on to Siliguri through the day, roughly 40 km and 1.5–2 hours to Rangpo, at about ₹100–200 a seat. Traffic at Ranipool and Singtam can slow the trip.
Reserved car
A reserved car from Siliguri, NJP or Bagdogra to Rangpo costs roughly ₹2,500–3,500, and from Rangpo to Gangtok about ₹1,800–2,500. When NH10 is closed, cars detour via Kalimpong, Pedong and Rhenock, which takes much longer.
Rail, in future
The Sivok–Rangpo railway is being built to bring trains to Rangpo. It was still under construction at the time of writing, with no passenger service. Until it opens, NJP is the nearest railhead, about 85–90 km away. Check current status before you travel.
Where to stay
Very few travellers sleep in Rangpo; Gangtok is under two hours away and the hill towns are cooler and quieter. If a road closure or late arrival leaves you stranded, the town has simple hotels and lodges along NH10 and in the bazaar at roughly ₹1,000–2,000 a room, aimed at business travellers and drivers. Look at the room before paying, ask about water and power backup, and avoid buildings close to the riverbank in the monsoon. Majitar, a few kilometres up the road, also has a handful of lodges near the engineering college.
Local tips
Check the state of NH10 on the morning you travel, through your driver or local news, as closures between Sevoke and Rangpo can last days.
Foreign travellers should carry their passport, Indian visa, printed permit if applied online, and passport photos for the Rangpo checkpost.
Draw cash in Rangpo if you are heading to Rongli or the Silk Route, as ATMs beyond are unreliable.
Avoid walking on silt flats or damaged banks near the river; the Teesta can rise fast after rain upstream.
Do not trespass on railway construction sites to look at tunnels or bridges; watch from public roads only.
Rangpo is a border town on NH10 where West Bengal meets Sikkim, at the confluence of the Rangpo Chu and the Teesta. It lies about 75 km from Siliguri and about 40 km from Gangtok, at roughly 300–350 m. Almost all road traffic into Sikkim from Siliguri passes through it.
Do I need a permit at Rangpo?
Indian nationals need no permit to enter Sikkim, only photo ID for any checks. Foreign nationals need a free Restricted Area Permit, which has been available online and at the Rangpo checkpost with a passport, visa and photos. Rules change, so check current status before you travel.
Is NH10 open between Siliguri and Rangpo?
NH10 has had repeated closures since the October 2023 Teesta flood, especially between Sevoke, Melli and Rangpo, and closures can last days or weeks in the monsoon. When it is shut, traffic detours via Kalimpong and Rhenock or via Lava. Check current status before you travel.
When will the Sivok–Rangpo railway open?
There was no confirmed opening date at the time of writing. The line has been under construction for years, and targets have slipped more than once. Check current status before you travel. Until it opens, NJP near Siliguri is the nearest railway station.
How far is Gangtok from Rangpo?
Gangtok is about 40 km from Rangpo, usually 1.5–2 hours by road via Singtam and Ranipool. Shared jeeps cost about ₹100–200 a seat and a reserved car about ₹1,800–2,500. Traffic near Ranipool can add time.
How did the 2023 flood affect Rangpo?
The glacial lake outburst flood of 3–4 October 2023 flooded low-lying parts of Rangpo along the Teesta, left heavy silt and damaged NH10. Much has been cleared or rebuilt, but damage is still visible and the highway remains prone to closure. Check current status before you travel.
Is Rangpo worth staying in?
Not usually. Rangpo is a practical border town, hot and busy, and most travellers pass through in under an hour. Stay only if a road closure or late arrival makes it necessary; simple hotels cost about ₹1,000–2,000 a room.
Can we go from Rangpo to the Silk Route directly?
Yes. From Rangpo a road runs up the Rangpo Chu valley to Rorathang and Rongli, where Indian travellers get the Silk Route permit. This avoids going to Gangtok first and suits travellers coming from Siliguri. Arrange the permit in advance through your driver or homestay.
What is the best time to travel through Rangpo?
October to March is best, with dry roads and fewer closures. April and May are hot in the valley but usually fine. From June to September the monsoon brings frequent landslides on NH10 near Rangpo, so build in spare days and check current status before you travel.
