A continuous road from Surkhet to Simikot exists, and has since July 2025, when a steel Bailey bridge over the Chuwa Khola at Kharpunath closed the last gap. It is unpaved and single-lane for the Humla section, cut from cliff for long stretches, crossed by waterfalls and closed by weather. Flights into Simikot remain the dependable way in.
Is there a road to Simikot?
Yes. This is the fact that most published material about Humla still gets wrong, including pages on this site until they were corrected. Simikot was widely described as the last district headquarters in Nepal without a road connection, and the reason was one river confluence rather than the whole route. In July 2025 the Nepal Army completed a 170-foot steel Bailey bridge at Kharpunath Rural Municipality-5 and the corridor became continuous. The bridge post covers what that changed and what it did not.
What follows describes riding that road north in monsoon 2026, by motorbike, from Surkhet to Simikot. Conditions on a track like this are a snapshot rather than a specification, and the season they were observed in was the worst one available.
Surkhet to Kalikot: the Karnali Highway
The journey starts at Surkhet, which is the road head in the useful sense: the last place with fuel pumps, banks, a proper bazaar and vehicles that will take you north. The Karnali Highway runs from here up into the hills.
This leg is the most travelled part of the whole route and it has its own page. The jeep ride to Jumla covers the shared-jeep reality, seat choice and what the Highway drive is actually like, and there is no point repeating it here. The short version is that it is paved in parts, unpaved in more parts, and slower than the map distance implies by a wide margin.
Through Kalikot the road follows the Karnali in a deepening gorge. This is the last district with anything approaching normal road infrastructure, and it is where the character of the journey changes. North of here the route into Humla leaves the Highway proper.
Into Humla: the valley floor to Sarkegad
The Humla section begins on the valley floor, low, hot and subtropical, with the Karnali wide and brown beside the track. Anyone expecting a Himalayan district from the start will be surprised: this is around 1,500 m, and in summer it is humid.
Sarkegad, at about 1,500 m, is the practical gateway. It has a campus, a health post, general shops, trail hotels and fuel sold from bottles and jerry cans. Most importantly it is the last place on the route with reliable phone coverage and anything resembling a supply chain. Everything you have not sorted here you carry to Simikot or do without, including fuel, which is covered in detail in the fuel and spares guide.
Surface on this stretch is unpaved and dust-heavy in dry weather, and soft and rutted in wet. The gradient is gentle by the standards of what comes next. The problems here are the side streams, which cross the track rather than passing under it, and washouts where the river has taken a bite out of the alignment.
Sarkegad to Srinagar: the track gets serious
Above Sarkegad the road climbs onto the gorge wall and stays there. Srinagar, in Adanchuli Rural Municipality at about 1,650 m, sits above the Karnali on terraced slopes growing barley, finger millet and buckwheat.
The track to it is narrow and cut into schist, which is the material fact of this stage. Schist breaks up, absorbs water and slumps, and after heavy rain sections of this road simply are not there. Village workshops here can weld a farm tool. They have nothing at all for a motorcycle or a modern four-wheel drive.
Riding it, the single-lane width is what you notice. There are passing places, and they are where somebody decided to make one rather than where you would want one. Meeting a loaded vehicle on the wrong section means one of you reverses, and it is worth knowing in advance how far back your own last passing place was.
Srinagar to Kharpunath: cliff, waterfalls and the confluence
This is the hardest and the most spectacular stage, and it is where the road stops being a road cut into a hillside and becomes a shelf cut into a cliff.
The track runs with the rock wall on one side and the drop to the river on the other, with very little between. Waterfalls come off the wall above and run straight across the surface, so the track is wet in places regardless of the weather that day. Where the water crosses, the surface is scoured to rock or built up with loose stone, and both are worse than the dry sections either side.
Rockfall is continuous rather than occasional. In monsoon 2026 there was fresh material on the track at multiple points, some of it recent enough that nothing had driven over it. The correct response is to look up before stopping, not to stop under an active slope, and not to linger anywhere with a fresh fan of rubble across the road.
Kharpunath sits at about 2,100 m at the confluence where the Chuwa Khola joins the Humla Karnali, between vertical cliff faces. This is the choke point that kept Simikot severed from the road network until the Bailey bridge went in.
Kharpunath to Simikot: the last climb
From about 2,100 m at the confluence to about 2,910 m at Simikot, the road climbs onto the ridge system the town sits on. The gradient here is the steepest sustained section on the route, and it is where a loaded vehicle and thin air start to argue with each other.
Fuel consumption on this stage is nothing like a flat-road figure. Low-gear crawling at altitude eats fuel, and anyone who budgeted from a highway number will arrive short. Budget substantially higher, and carry a reserve you have not counted.
Simikot arrives suddenly, as an airstrip on an open ridge with a town on both sides of it: the lower bazaar with the offices and cell towers, and the upper stone village above. The Humla district guide covers the district you have arrived in, and the acclimatisation profile explains why arriving here by road is easier on the body than arriving by air.
The stages at a glance
| Stage | Approximate elevation | Surface and character |
|---|---|---|
| Surkhet | Lowland road head | Pumps, banks, bazaar. The last normal infrastructure |
| Surkhet to Kalikot | Rising through the hills | Karnali Highway. Part paved, part not. Slow |
| Sarkegad | about 1,500 m | Valley floor, subtropical. Shops, signal, bottled fuel |
| Srinagar, Adanchuli | about 1,650 m | Narrow track cut into schist. Slumps after rain |
| Kharpunath | about 2,100 m | Cliff shelf, waterfalls across the track, the Bailey bridge |
| Simikot | about 2,910 m | Steepest sustained climb. Airstrip on an open ridge |
How long it takes and when it is open
Nobody should plan this route to a timetable. It is open when it is open, and the people who know are the drivers who came down it that morning. A section that slumps takes days or weeks to reopen depending on where it is and what else needs repairing first.
The seasonal picture is simple enough. The dry months either side of the monsoon are the working windows. Monsoon brings landslides and washouts, covered in the monsoon conditions post. Winter brings snow on the higher sections and cold that makes a breakdown a different kind of problem, and the seasons guide sets out the general windows.
The honest advice for most travellers is still to fly to Simikot from Nepalgunj and treat the road as something to know about rather than something to use. The overland route is worth doing if the journey itself is the point. It is a poor way to arrive somewhere on a date.
What the road has not replaced
Wheels reach Simikot. They do not reach most of Humla. North of the town, the route toward the border is a different proposition, described in the Simikot to Hilsa road guide, and beyond the road head everything still moves by mule and by porter. Mule caravans on the Karnali covers that system, which the bridge at Kharpunath has not made redundant.
What vehicle you need
High clearance and low gearing, in that order. The route is a working track rather than a road in the sense most drivers mean, and the requirement is set by the worst hundred metres rather than the average condition.
A four-wheel drive with genuine ground clearance, decent tyres and a driver who has done it before is the low-risk option, and it is what local traffic uses. A capable dual-sport motorcycle is the other option and is a different trip: lighter, more manoeuvrable when meeting oncoming traffic on a single-lane shelf, and far more exposed to weather, fatigue and the consequences of a small mistake.
What rules itself out is anything low, anything with a long wheelbase, and anything with road tyres. Waterfalls running across a rock shelf, loose stone on a steep gradient and stream crossings with unreadable bottoms are not conditions any of those survive.
Whatever you take, it goes in carrying its own spares and its own fuel margin. There is no workshop and no forecourt in the district, which is set out in the fuel and spares guide.
Where you sleep and eat on the way
Trail hotels, and the arrangement is consistent across the corridor. A dormitory or a shared room, dal bhat cooked once and served twice, a shared pit latrine and washing from a bucket or a tap in the yard. Nobody takes bookings and nobody needs to: you arrive, you ask, and there is a bed or there is not.
The food changes as you climb, which is the most reliable indicator of where you are. On the valley floor around Sarkegad it is rice with fresh vegetables from ground that grows them. Higher up, rice gives way to the barley, buckwheat and potato staples of the middle and upper villages, and fresh vegetables become an occasional event.
Plan stages around settlements rather than around distance, and stop earlier than feels necessary. Being caught out after dark on a single-lane cliff shelf is the specific thing to avoid, and there is no scenario in which pressing on for another hour is worth it.
Carry cash in small notes for all of it. There is no reliable card access anywhere north of the lowlands and change for a large note is genuinely scarce.
Before you travel. Humla is a restricted border district and conditions change without notice. Roads close, flights are cancelled, permit rules and fees are revised, and the Hilsa crossing opens and shuts to different categories of traveller. Confirm the current position with the District Administration Office in Simikot, the Department of Immigration, or a registered local operator before you commit to a route.
Frequently Asked Questions
Is there a road from Surkhet to Simikot?
Yes. The corridor became continuous in July 2025 when the Nepal Army completed a 170-foot steel Bailey bridge over the Chuwa Khola at Kharpunath Rural Municipality-5. The Humla section is unpaved, single-lane and seasonal.
How long does the drive take?
There is no dependable answer, and any figure would be misleading. The road closes with weather, sections slump and reopen on their own schedule, and vehicles run when drivers judge it passable. Plan in days with slack, not in hours.
Is the road paved?
Not in Humla. The Karnali Highway leg from Surkhet is partly paved. From the Humla valley floor northward the surface is dirt, loose stone and rock, single-lane, with waterfalls running across it in places and continuous rockfall on the cliff sections.
Should you drive to Humla or fly?
Fly, unless the journey is the reason you are going. Flights into Simikot from Nepalgunj remain the dependable way in. The road is real but new and fragile, and it is a poor choice for anyone who needs to arrive on a particular day.
Where is the last fuel before Simikot?
There is no filling station in Humla at all. The last pumps are down in the lowlands. From Sarkegad northward fuel is decanted from drums, bottles and jerry cans, often carrying sediment or cut with kerosene. Carry a filter funnel and a reserve.
Can a normal car do this road?
No. It is a route for high-clearance four-wheel drives and capable motorcycles. Single-lane cliff sections, water running across the surface, loose stone and steep sustained gradients rule out anything else.
What is the hardest section?
Srinagar to Kharpunath, where the track is a shelf cut into cliff with waterfalls crossing it and rockfall on the slope above. The steepest sustained climb is the last stage from Kharpunath up to Simikot.
Is the road open in monsoon?
Sometimes, and unpredictably. It was ridden in monsoon 2026, which is not a recommendation. Landslides, washouts and side streams in flood close sections without warning and reopen them on no schedule.
