Planning a Spiti Valley road trip or bike trip usually begins with one important question:

Should you enter Spiti from Shimla or Manali?

Both routes eventually lead to Kaza, but the experience is completely different.

The Shimla–Kinnaur route is longer, offers more gradual altitude gain and passes through places such as Narkanda, Kalpa, Nako and Tabo.

The Manali route is shorter but far more abrupt, taking travellers quickly into high-altitude terrain and across Kunzum Pass at around 4,550 metres.

For most first-time travellers—and particularly for a Spiti Valley bike trip—our preferred route is to enter through Shimla and exit through Manali.

Here’s why.


The Two Main Routes to Spiti Valley

Spiti can be approached from two directions.

Route 1: Shimla to Spiti

Shimla → Narkanda → Rampur → Kinnaur → Kalpa → Nako → Tabo → Kaza

The official Lahaul & Spiti district website lists the Shimla–Kaza route at approximately 412 km and describes it as an almost all-weather road up to Kaza.

Route 2: Manali to Spiti

Manali → Atal Tunnel/Lahaul → Gramphu → Batal → Kunzum Pass → Losar → Kaza

This route depends heavily on the seasonal opening of Kunzum Pass and the road towards Batal and Losar.


Shimla Route: The Better Way to Enter Spiti

If you’re visiting Spiti for the first time, the Shimla route has several advantages.

1. More Gradual Altitude Gain

This is probably the biggest reason we prefer entering through Shimla.

Instead of climbing immediately into extreme altitude, the journey builds gradually through:

Shimla → Narkanda → Kinnaur → Nako → Tabo → Kaza

For example, Nako sits at approximately 3,662 metres, while destinations farther into Spiti gradually take you higher.

This doesn’t eliminate the possibility of altitude sickness, but the slower progression gives your body more time to adjust compared with rapidly crossing a very high mountain pass.

For first-time Himalayan travellers, that makes a significant difference.


2. More Places to Experience Along the Way

The Shimla route isn’t simply a road to Spiti.

It is a journey through Kinnaur and the upper Sutlej Valley.

Depending on your itinerary, you can experience:

  • Narkanda
  • Sangla
  • Chitkul
  • Kalpa
  • Kinnaur
  • Nako Lake
  • Gue
  • Tabo Monastery
  • Dhankar

By the time you reach Kaza, you’ve already experienced several completely different Himalayan landscapes.


3. Available for More of the Year

The Shimla side has a major advantage when it comes to accessibility.

The district administration describes the Shimla–Kaza road as almost all-weather, while the Kunzum route can remain closed through winter because of heavy snowfall.

This is why winter Spiti trips normally enter and return through the Shimla–Kinnaur side.


4. Excellent for Motorcycle Riders

For riders, the transition is fantastic.

You begin with relatively greener mountain scenery around Shimla and gradually move towards the dramatic cliffs of Kinnaur before entering Spiti’s barren cold-desert landscape.

The changing terrain makes the ride feel like a journey rather than simply a transfer to Kaza.


Disadvantages of the Shimla Route

The main disadvantage is time.

It is the longer approach to Kaza and ideally shouldn’t be rushed.

If you’re starting from Chandigarh, a comfortable journey usually requires multiple overnight stops before reaching Kaza.

But for a Spiti trip, we don’t really see this as wasted time.

Kinnaur, Nako and Tabo are part of the experience.


Manali Route: Shorter but More Adventurous

The Manali side gives you a completely different introduction to Spiti.

Instead of slowly gaining altitude, the route quickly takes you into some of the journey’s highest terrain.

The major landmark is Kunzum Pass, approximately 4,550 metres high, which connects Lahaul with Spiti.


1. The Route Is Much More Dramatic

The journey around Gramphu, Batal and Kunzum provides the kind of rugged Himalayan terrain many riders imagine when planning Spiti.

Expect:

  • Rocky roads
  • High mountains
  • Water crossings depending on conditions
  • Rough sections
  • Isolated landscapes
  • Rapid weather changes

For adventure riders, it’s unforgettable.


2. Easy to Combine With Chandratal

One of the biggest advantages of this side is Chandratal Lake.

Chandratal lies around 21 km from Kunzum Pass, making it a natural stop while travelling between Spiti and the Manali/Lahaul side.

A typical summer route can therefore become:

Kaza → Losar → Kunzum Pass → Chandratal → Manali

This is one reason we love using the Manali side as the final section of a Spiti bike trip.

You finish with some of the most adventurous riding of the entire journey.


The Biggest Problem With Entering From Manali: Altitude

This is the main reason we generally don’t recommend the Manali route as the first approach for travellers who haven’t acclimatised.

You can go from roughly 2,000 metres around Manali to over 4,500 metres at Kunzum Pass within a relatively short period.

That’s a substantial altitude change.

You then continue through Losar towards Kaza, which itself lies well above 3,000 metres.

Even though every traveller responds differently to altitude, gradual ascent is preferable when your itinerary allows it.

That is why the Shimla-in, Manali-out direction usually makes more sense.


Manali Route Is Seasonal

Unlike the Shimla approach, the route through Kunzum isn’t available year-round.

Official district information states that the road connecting Lahaul and Spiti through Kunzum can remain closed from approximately October/November until June/July, depending on snowfall and snow clearance.

Himachal Tourism also lists regular Manali–Kaza bus connectivity mainly during the summer season.

Never assume the road is open simply because you’re travelling in June.

Always check the latest conditions.

Best Route for a Spiti Bike Trip

For a complete summer motorcycle journey, our preferred direction is:

Chandigarh → Shimla → Narkanda → Kinnaur → Nako → Tabo → Kaza → Chandratal → Manali → Chandigarh

Why?

Because it gives you:

Gradual altitude gain → Kinnaur → ancient Spiti → Kaza sightseeing → Kunzum → Chandratal → adventurous Manali exit.

The journey becomes progressively more dramatic rather than putting the most demanding high-altitude section at the beginning.


What If Kunzum Pass Is Closed?

Then don’t force the circuit.

Simply return through the Shimla side:

Kaza → Tabo → Nako → Kinnaur → Shimla

This is common during:

  • Winter
  • Early-season trips
  • Late-season trips
  • Unexpected snowfall
  • Temporary road closures

Mountain itineraries should always have some flexibility.


Important Note for Foreign Travellers

Indian citizens do not normally require a permit simply to enter Spiti.

However, foreign nationals travelling through the Shimla–Kinnaur side may require an Inner Line Permit for the protected border-region route. Himachal Tourism specifically notes this requirement for foreign tourists entering through Kinnaur.

Permit requirements should be confirmed before travelling because regulations can change.


So, Which Spiti Route Is Better?

Choose Shimla if:

  • This is your first Spiti trip
  • You want better acclimatisation
  • You’re riding a motorcycle
  • You want to explore Kinnaur
  • You’re travelling outside peak summer
  • You prefer a gradual journey into Spiti

Choose Manali if:

  • You’re already acclimatised
  • Kunzum Pass is open
  • You have limited time
  • You want a more rugged route
  • You’re combining the journey with Chandratal

Our Recommendation

Enter Spiti through Shimla and exit through Manali.

For most summer travellers, this gives the best combination of acclimatisation, scenery, culture and adventure.


Ride the Complete Spiti Circuit

There isn’t really a competition between Shimla and Manali.

The best Spiti adventure lets you experience both.

Start gradually through Shimla and Kinnaur. Ride deeper into the ancient villages of Spiti. Explore Kaza. Cross Kunzum. Spend time near Chandratal. Then finish through the rugged road towards Manali.

At Spiti Riders, our routes are planned around the season, current road conditions and the pace needed to actually enjoy the Himalayas.
