Koksar Village
The first Lahauli village on the old Rohtang route, now a tea and check post halt 7 km east of the Atal Tunnel exit, sitting at around 3,140 metres on the Chandra river
What makes it special
Koksar is a small Lahauli village on the right bank of the Chandra river at around 3,140 metres, roughly 7 km east of the Atal Tunnel north portal. Historically it was the first settlement travellers reached after crossing Rohtang Pass, and it sat on the old trade route that connected the Indian plains to West Asia through Lahaul and Ladakh. Since the Atal Tunnel opened in 2020, the valley's main traffic has shifted towards Sissu, and most of what Koksar was before has quieted down. What remains is useful, just not in a showy way.
The practical reality for today's traveller. Koksar is a tea and dhaba halt, a police check post where the Lahaul and Spiti administration logs vehicles heading towards Chandratal and Spiti via the Gramphu junction, and a small cluster of homestays for people who want to avoid the Sissu crowd for a night. On most summer days the stop takes 20 to 40 minutes, enough time for chai, a short walk along the river, registration at the check post if you are going deeper, and a look at the Chandra running wide and blue below the highway. The Gramphu junction, which is where the old road to Rohtang and the diversion to Kaza and Chandratal branches off, is about 5 km further east.
Koksar's more interesting claim is the weather. It is generally described as the coldest inhabited place in Lahaul, the stretch of valley where winter settles in hardest and lasts the longest. The Chandra freezes here in deep winter, and older residents still talk about using the ice as a crossing in the days before bridges. The surrounding slopes are avalanche prone and blocks of old avalanche debris can be seen near the river bed through much of spring. The state PWD rest house across the river on the left bank is an old landmark from the pre tunnel era, when this was the natural halt for anyone crossing Rohtang.
Short verdict. If you are driving through, stop for tea and a river walk. If you are heading to Chandratal or Spiti via Gramphu, make the check post registration your first priority so you do not lose time later. Stay a night only if Sissu is full, you specifically want a quieter village, or you are chasing a winter snow experience and the road is safe on the day. For everyone else, 30 minutes is the right length of relationship with this place.
Is Koksar worth stopping at?
Yes as a short tea stop and a logistical halt, not as a destination on its own. The dhabas are no-nonsense, the river walk is a pleasant leg stretch, and if you are continuing towards Chandratal, Kunzum Pass, or Spiti, the police check post here is where you register. For most travellers, 20 to 40 minutes is the right length of stop. If you want a Lahaul village to spend real time in, Sissu, Keylong, or Jispa work better.
Do I need to register at the Koksar check post?
Usually yes if you are continuing east towards Gramphu, Chandratal, Kunzum Pass, or Spiti. A seasonal Lahaul and Spiti police check post operates here and generally asks vehicles to register, especially through May to October. Keep ID, vehicle papers, and a pen ready and build in 10 to 20 minutes. Foreign travellers are asked to register passport details. Exact rules shift year to year, confirm locally on the day.
Can you stay a night in Koksar?
Yes, a few small homestays and the state PWD rest house operate in the warmer months, roughly April to October. This is a thinner option than Sissu or Keylong. Stay here if Sissu is full, you want a quieter village, or you are chasing the coldest inhabited place in Lahaul experience. Confirm availability in writing before you drive up, especially in winter when most stays shut or run on reduced services.

How to reach Koksar Village
6 approach routes with seasonal access
From Manali (via Atal Tunnel)
Year round via the Atal Tunnel. Road beyond the tunnel can be icy or snow blocked in deep winter.The year round standard approach. From Manali, take NH3 south to the Atal Tunnel south portal at Dhundi, which is about 25 km out. The tunnel is roughly 9 km and takes 15 to 20 minutes at the posted speed. Exit the north portal, head east towards Koksar, and reach it in about 7 km along the highway. Total drive from Manali is around 42 km and 1.5 to 2 hours with normal traffic. In peak summer and on weekends, the tunnel can queue for 30 to 60 minutes at the south portal. Leave Manali by 7 or 8 AM.
Fuel stop: Fill up in Manali. Next pump is at Tandi, about 40 km west via Sissu.
From Manali (via Rohtang Pass, old road)
Roughly late May to October, weather dependent, and subject to permit rules. Often closed in monsoon.The old seasonal route over Rohtang Pass itself, only open in summer, roughly late May to October. Requires a Rohtang Pass permit if coming from the Manali side, booked in advance through the official portal. Drive time is much longer and more tiring than the tunnel route. Only worth it if you specifically want the old road, you have a permit, and the pass is open on the day. Most travellers use the tunnel.
Fuel stop: Fill up in Manali, next is at Tandi via Sissu side.
From Sissu
Year roundA short drive east along the Chandra river from Sissu to Koksar. If you are overnighting at Sissu and want a shorter Lahaul day, this is the drive. Follow the highway past the tunnel exit junction and continue east along the river. Road is mostly in decent shape but can be patchy after monsoon.
Fuel stop: No pumps on this stretch. Fill up at Tandi or in Manali.
From Keylong
Year roundThe reverse direction if you are coming back from Spiti, Chandratal, or Baralacha La. From Keylong, drive west to Tandi, continue through Gondhla and Sissu, and pass the tunnel exit junction to reach Koksar. A comfortable drive, mostly tar, with the Chandra river alongside for most of it.
Fuel stop: Tandi petrol pump between Keylong and Sissu, about 30 km from Koksar
From Chandratal
Roughly June to October, weather dependentThe hard drive from the Spiti side. From Chandratal, backtrack through Batal and Kunzum Pass to Gramphu, then down the short 5 km stretch to Koksar. The road between Batal and Gramphu is among the roughest in Himachal, narrow, with multiple stream crossings, and open only roughly June to October. Build in 5 to 6 hours at minimum, sometimes longer. Not recommended for first time mountain drivers or any vehicle with low ground clearance.
Fuel stop: No pumps on this stretch. Fill up in Kaza before heading back.
From By bus from Manali
Year round via tunnel, summer only via old roadHRTC buses running from Manali towards Keylong or Leh use the tunnel route and pass through Koksar via the Sissu side. Frequency varies by season, generally a few services a day in summer, fewer in winter. Old Rohtang route buses run only in the summer window when the pass is open, and those were the traditional way to reach Koksar before the tunnel. Confirm timings at the Manali bus stand on the day of travel. The bus drops you on the highway at Koksar, dhabas and homestays are short walks from the road.
Fuel stop: Not applicable
Best time to visit
Season-by-season breakdown to help you plan
Clearest window for a comfortable stop, and the road to Spiti generally opens in this period
The best window for a Koksar halt. Snow has cleared from the village and most of the approach, dhabas open up through May, and the Chandra runs clear and strong with fresh snowmelt. Days are warm enough for a t-shirt at the dhaba, nights still need a jacket. Late May to mid June is when the Gramphu to Batal road opens for Chandratal and Spiti, so if you are doing a circuit, this is the window. Book ahead if you plan to overnight, there are not many rooms in Koksar to start with.
Green and wet, the valley looks good but roads can play up
Green valley, full Chandra, peak traffic on the tunnel, and the real monsoon risk. Koksar sits in a partial rain shadow so direct rain is less than in Manali, but the approach to the Atal Tunnel on the Kullu side can see landslides and debris flows, and the Gramphu to Batal road becomes unreliable. Keep a buffer day in your plan. Afternoon cloud cover is common, cutting into views. If you are continuing to Chandratal, travel in the morning, not after lunch.
Sharpest light, thinnest crowds, and the last window for the Spiti circuit
If you can time it, late September to mid October is the sharpest Koksar experience. Air clears, the high peaks stand out, the crowds drop off, and the morning light on the Chandra valley is the best of the year for photographs. Nights get cold quickly by October, carry a proper warm layer. This is also the last reliable window for the Chandratal and Kunzum Pass road, which generally starts to close in October with the first snow.
The coldest pocket of Lahaul, worth a visit only for experienced travellers with flexible plans
The reason some travellers specifically come, and the reason most others do not. Koksar is generally the coldest inhabited place in Lahaul, with night temperatures commonly below minus 10 and sometimes into the minus 20s on the coldest nights per local accounts. The Chandra freezes in large stretches, the slopes are avalanche prone, and heavy snowfall can block the road for days. Most dhabas shut or run limited hours, and most homestays either close or run on reduced services. The Atal Tunnel keeps access open, but the short stretch from the tunnel exit to Koksar via Sissu can be icy. Carry chains, proper layers, and a flexible plan. Not a casual season.
Things to see & do
7 experiences at Koksar Village
Tea and a simple meal at a highway dhaba
20 to 40 minutesThe most common reason to pull over in Koksar. A handful of small dhabas and tea stalls run along the highway through the village, generally open from around April through October, with a couple staying open into winter on and off. Order a chai and something basic like Maggi, dal rice, or an omelette. The food is straightforward, cheap, and fine. Use the break to stretch, breathe, and check on the Chandra river below. This is also where you will casually pick up real time road information from truck drivers and taxis, which is often more useful than any app.
Register at the police check post if you are going deeper
10 to 20 minutesIf you are continuing from Koksar towards the Gramphu junction and onwards to Chandratal, Kunzum Pass, or Kaza, a seasonal Lahaul and Spiti police check post operates here and generally asks vehicles to register. Keep your ID, vehicle papers, and a pen ready, and build in 10 to 20 minutes for the entry. Timings and requirements vary by year and by season, so treat this as a moving target and ask your driver or homestay before you leave. Foreign travellers are asked to register passport details.
A short walk down to the Chandra river
15 to 30 minutesA short walk down from the highway gets you to the edge of the Chandra, running wide and milky blue over gravel banks. Find a flat rock, sit for ten minutes, watch the water. In deep winter the surface freezes over large stretches and you can see the ice where the flow slowed. Do not wade in. The current is stronger than it looks and the water is glacial.
Visit the village monastery and chorten
15 to 20 minutesThere is a small monastery and a roadside chorten at Koksar that most travellers drive straight past. The scale is modest, nothing like Kardang or Key, but walking up takes five minutes and gives you a quiet pause that the tea stalls do not. If a lama is around, a small offering is the usual convention. Keep voices down, remove shoes at the door, do not photograph interiors without permission.
Snow and frozen river experience in winter
1 to 2 hoursIf you are in Koksar between December and February, and the road is safe on the day, the frozen Chandra river, the avalanche debris along the slopes, and the snowbound village are the reason to be here. Most dhabas shut or run limited hours, so plan for a short halt rather than a full day. Carry chains for your tyres, proper thermals, and a backup plan to turn around if conditions change. Winter Lahaul beyond Sissu is not a casual day trip.
Drive to Gramphu junction for the road split
30 to 45 minutes round tripAbout 5 km east of Koksar the road forks. Left continues on the old Rohtang pass route that takes you over the top towards Manali. Right climbs into the high Spiti basin via Chhatru, Batal, and Kunzum Pass. The Gramphu junction is a genuinely dramatic geography lesson in one spot, the Chandra valley opens up, Bara Shigri glacier is visible in the distance on clear days, and the road surface changes from tarred to rough within a few hundred metres. Worth the short drive to stand there and look, even if you are not continuing onward.
Photograph the Chandra valley and the village
30 to 60 minutesEarly to mid morning light on the Chandra river, with Koksar's slate roofs and the Lahauli peaks behind, is the cleanest photographic window. In winter, midday is the only usable window because the sun clears the ridge late. Do not photograph villagers or inside homes without asking. The PWD rest house across the river and the old bridge are small but genuine pieces of pre tunnel Lahaul that photograph well.

~5 km · 10 min drive eastThe road junction 5 km east of Koksar where the old Rohtang road splits from the Spiti diversion towards Chhatru, Batal, and Kunzum Pass. Worth a short drive just to stand at the split and see the Chandra valley open up. The road beyond Gramphu towards Chandratal is among the roughest in Himachal, check status before continuing.
~14 km · 25 min drive towards the tunnel exitThe first village past the Atal Tunnel on the other side of the exit junction, with a roadside waterfall, a small lake, a helipad sunset viewpoint, and a growing collection of homestays. The natural pair with Koksar on a Lahaul day from Manali.
~14 km · 25 min driveA small man made lake at the edge of Sissu village near the helipad, 20 minutes west of Koksar. Works as a quick morning or afternoon pairing if you are overnighting at Koksar or passing through on a Lahaul day trip.
~25 km · 45 min drive westA seven storey Kathkuni tower from around 1700 AD, the only fort of its kind in Lahaul and Spiti, sitting above the Chandra river about an hour west of Koksar on the way to Keylong. Mostly an exterior visit since the fort is locked up, but worth 20 to 30 minutes.
~35 km · 1 hour drive westThe confluence of the Chandra and Bhaga rivers where they meet to form the Chenab, roughly 11 km west of Gondhla Fort and another natural pairing on the drive towards Keylong. A 15 minute halt for the viewpoint and a short walk.
~44 km · 1.5 hours drive westThe district headquarters of Lahaul and Spiti, with the only proper market in the valley, an ATM, fuel, a hospital, and the Kardang Monastery above the town. The natural base if you are doing a longer Lahaul itinerary that includes Koksar.
~63 km · 2 hours driveA quiet Lahauli village on the Bhaga river at around 3,200 metres with riverside camping. The standard overnight halt for travellers heading deeper towards Baralacha La and Ladakh.
~110 km via Gramphu and Batal · 5 to 6 hours driveThe natural crescent moon glacial lake at around 4,300 metres, the usual reason to turn east from Koksar into the Gramphu to Batal road. Not a day trip, plan an overnight at a camp or as part of a Spiti circuit.
~125 km via Gramphu and Batal · 6 to 7 hours driveThe high pass at around 4,551 metres that connects Lahaul to Spiti, generally open June to October. Reached from Koksar via Gramphu and Batal. Part of any Manali to Spiti circuit that uses the Lahaul route.
