Introduction
Spiti Valley is the kind of place where the journey is just as exciting as the destination. The roads get narrower, the mountains get bigger and, before you know it, you're driving through some of the highest landscapes in Himachal Pradesh.
For travellers planning a Spiti Valley road trip, understanding its high mountain passes is important because these routes can decide when you can travel and which side of the valley you can enter from. If you're planning your trip with Voyagers Beat, knowing the route and seasonal conditions beforehand can make the journey much smoother.
In this guide, we'll take you through the major high passes in Spiti Valley, their altitude, routes, best travel season, difficulty and a few practical things you should know before heading into the mountains.
Why Are High Passes Important in Spiti Valley?
If you've ever looked at a map of Spiti, you'll notice just how isolated the valley is. Mountains surround it from almost every direction, and reaching the region often means crossing high-altitude mountain routes.
That's what makes these passes so important.
They aren't simply places where you stop, click a few pictures and continue your journey. They are actual gateways connecting Spiti with places such as Lahaul, Kullu and Ladakh. The opening and closing of these routes can also have a big impact on travel plans.
For example, Kunzum La acts as an important gateway from the western side of Spiti. The official Lahaul & Spiti district administration describes Kunzum La as the pass connecting the upper Chandra Valley with Spiti and notes that a motorable road now runs through it. You can check the official pass information here.
So, before planning your Spiti Valley travel itinerary, it's worth understanding which passes you'll actually be travelling through.

The pass sits on the Manali-Kaza route and marks a dramatic change in scenery as you move from the Lahaul side towards the dry, rugged landscape of Spiti. The road itself is an adventure, with steep sections, mountain bends and constantly changing views.

Pin Parvati Pass
Altitude: Around 5,300-5,400 metres
Location: Between Parvati Valley and Pin Valley
Route: High-altitude trekking route
Best Time: Generally mid-July to early September
Difficulty: ChallengingPin Parvati Pass is where the experience changes completely.
Unlike Kunzum, this isn't a road-trip stop. Pin Parvati Pass is a demanding high-altitude trek that connects the greener Parvati Valley with the dry, rugged landscapes of Pin Valley.
The route involves steep sections, river crossings and glacier terrain. It's not the kind of trek you'd want to attempt without proper preparation, especially if you haven't spent much time at high altitude before.
Once you reach Pin Valley, you can explore attractions such as Kungri Monastery and the surrounding landscapes of the valley.
If you're planning this route, don't treat it like a regular weekend trek. Proper equipment, acclimatisation, weather checks and experienced trekking support can make a huge difference.
Parang La
Altitude: Approximately 5,580 metres
Location: Between Spiti and the Ladakh region
Route: High-altitude trekking route towards the Tso Moriri region
Best Time: Generally mid-July to early September
Difficulty: ChallengingFor travellers who want something more remote, Parang La offers a completely different kind of Himalayan experience.
This is a high-altitude trekking route connecting the Spiti region with the Ladakh side. There are long stretches where you'll see very little human settlement, which is exactly what attracts experienced trekkers to this route.
Cold temperatures, high altitude, long trekking days and difficult terrain make Parang La better to experienced trekkers rather than first-time hikers.
The route towards Tso Moriri adds another memorable element to the journey, especially for travellers who want to experience both Spiti and Ladakh in one adventure.

Best Time to Cross the High Passes in Spiti Valley
When planning a trip around the high passes in Spiti Valley, the season matters a lot.
The mountains don't follow a fixed tourist calendar, and road conditions can change depending on snowfall, rainfall and local weather.
June to October
This is generally the main travel period for the motorable Spiti routes. Kunzum Pass and the Manali-Kaza side become accessible during the open season, but exact opening dates can vary from year to year.
If you're planning a summer road trip, always check the latest road conditions before starting your journey.
Mid-July to Early September
For high-altitude trekking routes such as Pin Parvati Pass and Parang La, the trekking window is generally narrower.
Snow, river levels and weather conditions can make these routes difficult outside the preferred trekking season. Even during summer, conditions at these elevations can change quickly.
October Onwards
As temperatures drop and winter approaches, high-altitude routes can begin closing due to snowfall.
