Spiti Valley by Bus: Adventure Guide 2026- Route, Cost& Tips

A bus to Spiti Valley is not one vehicle for the whole journey, and that single fact decides everything else about the trip. Delhi to Kaza is 730 km on the Shimla and Kinnaur road, eighteen to twenty hours of driving that our route data recommends as a two-day trip, and only the first day of it is highway. Beyond Shimla or Manali the road narrows, loses its tarmac in stretches, crosses streams and climbs above 4,000 m, and our Delhi to Spiti bus page is plain about what that means: only buses up to 20 to 22 seats can attempt the route, even those face restrictions, and most groups switch to Tempo Travellers or SUVs beyond Shimla or Manali. This guide is about the bus itself - which sizes go where, what a bus day is actually like, where you sleep, how the altitude stacks up, and when each road is usually open.

The Bus Day, as a Timetable, Before the Itinerary

Before the sightseeing and the acclimatisation plan below, the mode question first: what a chartered bus actually does, hour by hour, on the Shimla and Kinnaur road, and what it costs. This is our own coach's schedule, not a public bus timetable — a hired bus keeps to no fixed departure time and stops where the group wants, but this is the shape our route data and drivers work to on a standard two-day run.

Day	Leaves	Passes / reaches	Distance covered	Vehicle for the stretch
Day 1	Delhi, around 4:00 AM	Breakfast at Chandigarh → Shimla bypass before noon → lunch at Narkanda → drops to the Sutlej at Rampur → up through Jeori, Jhakri, the Wangtu gorge → Reckong Peo by early evening	560 km, 13 to 14 hrs	Any size up to a full-size coach as far as Shimla/Narkanda; 20 to 22 seats from there
Night 1	—	Kalpa (about 2,960 m) or Nako (about 3,600 m) for groups sleeping higher	—	—
Day 2	Kalpa, morning	Nako → Sumdo check post → an hour at Tabo → Kaza, mid-afternoon	170 km, about 6 hrs	20 to 22 seats at most; most groups are in a Tempo Traveller or SUV by this stage

That is 730 km over two driving days. Our chartered coaches for this route are quoted from ₹45/km, which on the full distance is about ₹32,850 one-way before tolls, the Atal Tunnel toll where the Manali road is used, parking and the driver's night halt, all paid at actual; a return coach doubles the distance. Where the group is small enough that a bus is not the right vehicle at all, the cab fares — Ertiga, Innova Crysta, 12-seater Tempo Traveller — are in the "Who Should Take a Cab Instead" section below.

Which Buses Actually Run the Two Roads In

There are two roads into Spiti and both start as ordinary highway. The Shimla and Kinnaur road runs on NH-5 through Chandigarh, Shimla, Narkanda, Rampur, Reckong Peo, Nako and Tabo to Kaza. The Manali road runs on NH-44 and NH-21 to Manali, then through the Atal Tunnel, up the Chandra valley and over Kunzum La at 4,551 m before dropping to Losar and Kaza. On the highway sections of either, any coach in our fleet is comfortable. Past them, the size limit does the choosing for you.

Stage of the journey	What the road is	What can run it
Delhi to Chandigarh and on to Shimla or Manali	Standard highway; NH-44 four-lane to Chandigarh, then a maintained hill road	Any size, 22 seater up to 56 seater
Shimla to Narkanda, Rampur and Reckong Peo	Hill road cut into the Sutlej gorge; narrow in places, landslide zones	Up to 20 to 22 seats, with an experienced mountain driver
Reckong Peo to Nako, Tabo and Kaza	Unpaved patches, loose rock, high cold desert above 3,000 m	20 to 22 seats at most; most groups change to a Tempo Traveller or SUV
Manali to Gramphu, Batal and over Kunzum La	Unpaved from Gramphu with glacier-fed stream crossings at Chhatru and Batal	Not a bus road; Tempo Traveller or SUV with clearance

So the realistic shape of a group trip is a bus to the hills and something smaller beyond them. Our bus page lists the halts in exactly that order - Chandigarh, then Shimla or Manali, then Narkanda or Keylong depending on the road, then Kalpa or Sarchu, then Kaza - and the Chandigarh to Spiti bus route works the same way over 420 km and twelve to thirteen hours for groups flying or taking the train in. If you want the whole thing done in one vehicle, that vehicle is a 12-seater Tempo Traveller or an SUV, not a coach.

What a Bus Day to Spiti Is Actually Like

Long, and front-loaded. Our Kaza road guide builds day one around a four o'clock start from Delhi: breakfast at Chandigarh, past Shimla before noon on the bypass at about 2,200 m, lunch at Narkanda at about 2,700 m, then a drop of nearly two thousand metres to the Sutlej at Rampur, and up the river through Jeori, Jhakri and the Wangtu gorge to Reckong Peo by early evening. That is 560 km and thirteen to fourteen hours with halts, most of it on a hill road. Day two is short by comparison - 170 km and about six hours from Kalpa to Kaza.

• The pace is set by the road, not the timetable. Above Rampur the surface, the traffic and the weather decide the day. A slide or a cleared-and-reopened stretch can add hours, and our bus page says plainly that conditions change rapidly with the weather.
• Halts are where the villages are. Narkanda for lunch, Rampur as the last proper town before Kinnaur and the last place to buy anything forgotten, Reckong Peo to fill the tank.
• Connectivity thins out. Our travel notes for the route list limited mobile connectivity among the things to plan for, along with carrying warm clothes and medicines and booking homestays in advance.
• The second day is the reward. Nako, the Spiti meeting the Sutlej at Khab, the check post at Sumdo, an hour at Tabo, then Kaza in the mid-afternoon.

Where You Sleep

Nobody drives this in one push, and the halts are not interchangeable. On the Shimla side the standard night is Kalpa, the old village seven kilometres above Reckong Peo at about 2,960 m, facing the Kinner Kailash range across the valley. Nako, at about 3,600 m, is the alternative for groups who would rather sleep higher and shorten day two. For a party that finds thirteen hours on day one too much - and for families it usually is - our guide sets out a three-day version: Shimla or Narkanda on night one, Kalpa on night two, Kaza on the afternoon of day three, which also opens up Sarahan with its Bhimakali temple and the Baspa valley at Sangla and Chitkul as detours from the Rampur to Peo stretch.

In Spiti itself the accommodation is homestays and small guesthouses, which is why our route notes tell groups to book them in advance rather than arrive and look. A coach party of forty needs far more beds than Kaza, Tabo or Kalpa can produce at short notice in season, and that alone is a reason group trips here tend to run at Tempo Traveller size.

Altitude, in the Order It Happens

Kaza sits at about 3,800 m, higher than Leh, and the villages people visit from it - Langza, Komic, Hikkim and Kibber - are higher still. Altitude sickness is about the rate of ascent more than the height itself, so the sequence matters more than any single number.

• Day one, to about 2,700 m and back down. Narkanda is the high point of the first day before the road drops to the Sutlej at about 1,000 m. That dip is useful, not wasted.
• Night one, at 2,960 m or 3,600 m. Kalpa or Nako. Sleeping at a middling altitude after a long day is the whole argument for the Shimla side.
• Day two, to about 3,800 m. Nako, Sumdo, Tabo, Kaza. The gain has been spread across two days and roughly thirty-six hours, which is about what standard advice on acclimatisation asks for.
• First day in Spiti, do little. Key Monastery and the town, not Langza and Komic. Drink more water than you think you need from Rampur onwards, eat light, and do not push through a headache.
• If someone is unwell, go down. On the Shimla side going down is easy - Tabo is about 500 m below Kaza and Nako is on the road behind you. On the Manali side the only way down from Losar is back over a 4,551 m pass, which is the other argument against arriving that way.

The Manali road does the same climb in a single day: Manali at about 2,050 m to Kunzum La at 4,551 m, with the highest point of the whole trip in the middle of the drive. Our Delhi to Kaza route data says it in one line - going straight through is the main cause of altitude sickness on this route.

When Each Road Is Usually Open

The Shimla and Kinnaur road is the year-round one in principle and the one our bus page names as open all year, though heavy winter snow regularly cuts access and the practical season our route data gives is May to October. The Manali and Kunzum road is seasonal: Kunzum La is usually clear from roughly June to mid-October, the pass is snowed in through the winter, and the road is cleared each year once the snow allows - so early June is never guaranteed and the closing date depends on the first heavy fall. The Atal Tunnel has changed the first part of a Manali day, because Rohtang Pass no longer has to be crossed to reach Lahaul, but it has not changed Kunzum, which is where the season is decided. If a September or early-October return over Kunzum is part of the plan, confirm the pass before leaving. Our best time to visit Spiti Valley page goes through the months.

At Sumdo, where Kinnaur ends and Spiti begins, there is a check post. Indian nationals show identification; foreign nationals need an Inner Line Permit, issued by the district administration. We do not quote a fee for it here, because none is fixed on our pages - ask the issuing office or your operator when you apply.

Who Should Take a Cab Instead

Two to six people, a family, or anyone who wants one vehicle and one driver from Delhi to Kaza and back. A cab does not stop at Shimla or Manali and hand you to something smaller; it does the whole road, chooses the halts around the altitude, and waits at Kaza for the days in the valley. On the published rate card the 730 km two-day drive bills its distance - an Ertiga or SUV at ₹15/km is ₹10,950, an Innova Crysta at ₹18/km is ₹13,140 and a 12-seater Tempo Traveller at ₹23/km is ₹16,790. A sedan at ₹11/km comes to ₹8,030 but is not recommended beyond Reckong Peo, where the surface turns to loose rock. Tolls, the Atal Tunnel toll, parking and the driver's night halts are paid at actual.

The full comparison - which road to take, in which direction, and what each option costs over a six to eight day loop - belongs to a separate piece and we have not repeated it here. Read Delhi to Spiti Valley: bus or cab, and how the two roads in actually work for that decision, and the Kaza road guide for the stop-by-stop timeline both roads follow. For groups of eight to twelve who want to stay together the whole way, the 12-seater Tempo Traveller is the vehicle that goes where the coach stops.

Packing for a Bus Day at Altitude

• Warm layers, and more of them than the month suggests - Spiti is a high cold desert and the temperature falls hard after sunset
• Sunscreen and sunglasses; the light at 3,800 m is fierce even when the air is cold
• Medicines, including anything you normally take, and something for a headache
• A power bank, because charging is limited and a bus day is long
• Cash, since machines are scarce beyond Reckong Peo
• Identification for everyone in the party, for the check post at Sumdo

Frequently Asked Questions

Can a 45-seater Volvo go to Spiti Valley?

No. Our bus page is clear that only buses up to 20 to 22 seats can attempt the Spiti roads, and even those face restrictions. A large coach works as far as Shimla or Manali; beyond that most groups move to a Tempo Traveller or an SUV.

How many days does a bus trip to Spiti take?

Delhi to Kaza is 730 km and eighteen to twenty hours of driving, which our route data recommends as a two-day trip with a night at Kalpa or Nako. A three-day version with a night at Shimla or Narkanda first is gentler on the altitude and is what most families choose.

Which road into Spiti is open in winter?

The Shimla and Kinnaur road is the one that stays open longest and is open in principle through the year, though heavy snow regularly cuts access. The Manali road over Kunzum La is usually clear only from about June to mid-October.

Do I need a permit for Spiti Valley?

At the Sumdo check post Indian nationals show identification. Foreign nationals need an Inner Line Permit, issued by the district administration - check the current requirement and any charge with the issuing office when you apply.

Can buses reach Key Monastery?

Kaza is the practical end of the road for anything bus-sized. Key, Kibber, Langza, Komic and Hikkim are day runs from Kaza in a smaller vehicle, and the first day at 3,800 m is better spent on Key and the town than on the higher villages.
