I reached the Kaza bus stand at 4:30 AM. Dark. Cold. My breath fogged the air. Two HRTC buses sat idling in the yard. The Manali bus left at 5:00 AM sharp. I was on it. Twelve hours later, I stepped into Kaza.
That was the fastest way to reach Spiti Valley from Delhi I have found after three trips. The Delhi to Spiti Valley distance by bus is long. About 740 kilometers. But with the right route and timing, you can do it in two days.
No private taxi. No expensive tour package. Just a government bus and some patience. Let me show you exactly how.
How to Reach Spiti Valley from Delhi by Bus in 2026?
Before my first trip, Google showed 16 hours. Delhi to Kaza. Direct. I almost believed it.

Then a friend who lives in Himachal laughed at me. "You cannot drive that in 16 hours," he said. "The roads do not allow it."
He was right. The Delhi to Spiti Valley distance by road is not the problem. Mountain roads are. Hairpin bends. Narrow stretches. Sudden halts for sheep crossings. A 200 km stretch in the mountains takes 7-8 hours easily.
Do not trust the maps. Trust the bus schedules.
The Fastest Route: Manali via Atal Tunnel (When Open)
Here is the truth. The fastest way to reach Spiti Valley from Delhi is through Manali. But only for five months a year.
Route Breakdown
Delhi to Manali: Overnight Volvo from ISBT Kashmiri Gate. 12-14 hours. Leave Delhi at 6 PM or 7 PM. Reach Manali by 7-8 AM next day.
Manali to Kaza: HRTC bus leaves at 5:00 AM from Manali main bus stand. Reaches Kaza by 4:5 PM the same day. 11-12 hours.
Total travel time: Approximately 26-28 hours including the overnight in Manali.
Wait, two days? That is the fastest?
Yes. Because the alternative route takes three days minimum.
The Manali Route Map (Day by Day)
Day 1 - Delhi to Manali
Board any Volvo from ISBT Kashmiri Gate. Laxmi Holidays and HRTC both run this route. Fare in 2026: ₹900-1,200 for a semi-sleeper . The bus stops at roadside dhabas around midnight for dinner. Butter chicken and dal makhani taste better at 1 AM. Do not ask why.
You wake up in Mandi district. Green hills. Pine trees. The air smells different. By 7:30 AM, you are in Manali.
Day 2 - Manali to Kaza
Do not sleep in. The HRTC bus to Kaza leaves at 5:00 AM sharp. Late by five minutes? The bus leaves without you. No exceptions.
Get to the bus stand by 4:30 AM. Carry cash. The ticket counter opens at 4:15 AM. Fare for 2026: ₹450-500. No online booking for this route. Over the counter only.
The bus passes through Atal Tunnel (9 km long). Then climbs to Kunzum Pass at 14,931 feet. The views will break your brain. Brown mountains. Blue sky. Nothing else.
You reach Kaza by late afternoon. Check into Zostel or a homestay. Rest. Do not walk too much. Altitude is real here.
Day 3 (if needed) - Kaza to your Spiti destination
From Kaza, you take local buses or share taxis to Kibber, Langza, Hikkim, or Komic. These leave from the same bus stand. Fares: ₹50-150 depending on distance.
The Year-Round Alternative: Shimla Route (Slower but Safer)
If you travel between November and mid-June, the Manali route stays closed. Snow blocks Kunzum Pass. BRO starts clearing snow around late March, but full opening happens only by June.

In winter 2026, heavy snowfall blocked 292 roads in Lahaul and Spiti district alone. NH-505 (Kaza-Gramphu) remained closed until clearance operations began in late March.
So here is your winter route.
Delhi to Shimla: Overnight Volvo from ISBT Kashmiri Gate. 8-10 hours. Fare: ₹950-1,200.
Shimla to Reckong Peo: HRTC bus leaves at 6:30 AM from Shimla. Reaches Reckong Peo by evening. 9-10 hours.
Reckong Peo to Kaza: Next morning bus. 7-8 hours.
Total: Three days. Slower. But the road stays open almost year-round.
Delhi to Spiti Valley Distance by Bus (Exact Numbers)
Let me give you straight numbers. No guesswork.
| Route | Total Distance | Bus Travel Time | Days Needed |
|---|---|---|---|
| Delhi → Manali → Kaza | ~730 km | 24-26 hours | 2 days |
| Delhi → Shimla → Reckong Peo → Kaza | ~740 km | 32-36 hours | 3 days |
The Delhi to Spiti Valley distance by road is similar on both routes. The time difference comes from road conditions. Manali route climbs faster. Shimla route meanders through Kinnaur valley. More kilometers? Actually less. But slower driving because of narrower roads.

- Kaza (two nights): ₹800 per night for private room at homestay
Total trip cost (excluding activities): Approximately ₹6,500
If you do the Shimla route, add one more night of stay. Budget around ₹8,000-9,000 total.
Season Matters More Than Route
Here is the single most important thing I learned.
Manali route open: June to mid-October. Kunzum Pass gets snow from November onward. BRO starts clearing in late March, but the road becomes motorable only by June. Do not attempt before that unless you like walking in snow.
Shimla route open: Almost year-round, except during active heavy snowfall when roads temporarily close. January 2026 saw 565 roads blocked across Himachal, including key routes in Kinnaur. Always check weather before leaving.
Best months for Manali route: July, August, September. Roads are driest. Kunzum Pass is accessible. Chandratal Lake is visible (if you take a detour).
Avoid Manali route in: October end (early snow possible), any month before June.
What No One Tells You About the Manali-Kaza Bus
The bus is not comfortable. Let me be honest.
Old HRTC buses. Hard seats. The window may not close fully. Dust enters. At Kunzum Pass, the temperature drops to near freezing even in July. Bring a jacket.
The road is unpaved for long stretches between Batal and Kunzum. You will bounce. Your back will hurt. Accept this before you go.
The bus stops at exactly three dhabas. Chhatru. Batal. And somewhere near Losar. Each stop lasts 15-20 minutes. Do not wander far. The bus driver does not count heads. He leaves on time.
Sit on the left side of the bus from Manali to Kaza. That side faces the mountain views. The right side faces the valley drop. Both are fine. Left is better.
What to Pack for the Bus Journey
Non-negotiable items:
Power bank. The bus has no charging points. Your phone will die. Then you cannot take photos of Kunzum Pass. That hurts.
Snacks. Biscuits. Nuts. Chocolate. The dhaba food is fine but expensive for what you get. A Maggi costs ₹50-60. A small water bottle costs ₹30. Bring your own.
Warm layer. Even in July. Kunzum Pass sits at 14,931 feet. The wind cuts through regular jackets. Bring a fleece or a thin puffer.
Water bottle. Refill at dhabas. Stay hydrated. Altitude sickness hits harder when you are dehydrated.
Motion sickness tablets. The road from Gramphu to Kunzum has 23 hairpin bends. I counted. Take a tablet before the Atal Tunnel.
Altitude Sickness Warning (Serious)
The Manali route climbs too fast. You leave Manali at 6,726 feet. Six hours later, you cross Kunzum Pass at 14,931 feet . That is an 8,000 feet gain in half a day.
Your body needs time to adjust.
First time I did this route, I felt dizzy by the time we reached Losar. Headache started at Kaza. Took me two days to feel normal.
Prevention tips that actually work:
Drink water constantly. At least 3-4 liters on the bus journey day.
Do not sleep at Kunzum Pass. Stay awake. Regulate your breathing.
Carry Diamox (acetazolamide). Start taking it one day before Manali. Consult a doctor before.
If you feel severe headache, vomiting, or confusion, go down immediately. Do not "push through." Altitude sickness kills.
The Shimla route climbs gradually over three days. That is why beginners and families should take that route . Your body gets time.
ISBT Kashmiri Gate: Your Starting Point
The Delhi bus stand is chaotic. Give yourself one extra hour.
HRTC Volvo to Manali or Shimla leaves from platform numbers 20 to 24. Confirm on the digital board.
The waiting room is basic. No comfortable seating. Bring something to sit on if you arrive early.
Food inside the bus stand is overpriced and bad. Eat before you reach. There is a Haldiram's 5 minutes walking from Gate No. 1.
Buses leave on time. Do not be late.
Kaza to Manali Return Bus (Same Rules Apply)
The return bus from Kaza to Manali also leaves at 5:00 AM. Same counter. Same cash-only rule. Same hard seats.
Reach Kaza bus stand by 4:30 AM . In Kaza, mornings are dark and cold. Even in August. Wear everything you have.
The bus reaches Manali by 3:30-4:00 PM . From Manali, you can take an evening Volvo back to Delhi. That bus leaves around 6:00 PM to 8:00 PM. Book this online before you leave Delhi. Last minute tickets are hard to get.
Common Mistakes That Ruin the Trip
I made all of these. You do not have to.
Mistake 1: Assuming you can book Manali-Kaza bus online. You cannot. says it clearly. Over the counter only. I once reached Manali on a Sunday. Bus stand counter was closed. Spent an extra day waiting.
Mistake 2: Not carrying cash. The Manali-Kaza bus does not take cards or UPI. Neither do the dhabas on the route. Network is patchy. Cash works everywhere.
Mistake 3: Trusting weather apps. Mountain weather changes every hour. The Manali-Kaza bus runs regardless of light rain. Heavy rain or fresh snow? The bus may get canceled. Check with HRTC office in Manali before the travel day.
Mistake 4: Skipping acclimatization in Kaza. Your first day in Kaza, walk slowly. Do not attempt Kibber or Komic on day one. Altitude will punish you. Rest. Drink water. Skip the trek.
Mistake 5: Forgetting to book return Volvo from Manali. I made this mistake. Reached Manali after the Kaza bus. No seats left for Delhi that night. Spent an extra ₹2,000 on a private cab to Chandigarh. Learned my lesson.
Who Should Take Which Route
Take the Manali route if:
- You are traveling between mid-June and mid-October
- You have been to high altitude before (Leh, Ladakh, or similar)
- You want the fastest way to reach Spiti Valley from Delhi
- You do not mind bumpy roads and basic buses
Take the Shimla route if:
- You are traveling between November and May
- This is your first high-altitude trip
- You want to see Kinnaur valley (beautiful apple orchards and temples)
- You have 3-4 extra days to spare
- You are traveling with family or older people
Final Verdict
The fastest way to reach Spiti Valley from Delhi by bus is clear. Overnight Volvo from Delhi to Manali. Next morning 5:00 AM HRTC bus to Kaza. Two days. Approximately ₹6,000-7,000 total for buses, food, and basic stay.
The Delhi to Spiti Valley distance by bus is long. But the journey is the point. You pass through Atal Tunnel. You cross Kunzum Pass. You see the Spiti river turn from green to brown. You arrive in Kaza exhausted but happy.
Do not overplan. Do not overpack. Just book the Volvo, reach the Manali bus stand at 4:30 AM, and trust the HRTC driver. He has done this route a thousand times.
See you in Spiti.
