Decoding the Permit Puzzle
The first step in planning is understanding permit requirements, which differ based on nationality. For Indian citizens, the good news is you do not need an Inner Line Permit (ILP) or any special permission to travel through the main tourist circuits
of Kinnaur and Spiti. All you need to carry is a valid government-issued photo ID like an Aadhaar card or passport for routine registrations at police checkposts like Jangi and Sumdo. For foreign nationals, the rules are different. A Protected Area Permit (PAP), often colloquially called an ILP, is mandatory to travel beyond certain points. If entering from Shimla, this permit is required to go past Jangi in the Kinnaur district. It is also needed for restricted areas in Spiti Valley itself, including Kaza, Tabo, and Dhankar. The permit can be obtained from the District Magistrate (DM) or Sub-Divisional Magistrate (SDM) offices in Shimla, Reckong Peo, Kaza, or Keylong. Reckong Peo is the most popular and efficient place for travellers on the Shimla-Kaza route to get this permit. As of 2026, there is no online system for the PAP; it must be done in person.
Choosing Your Route: Shimla vs. Manali
There are two primary routes into Spiti Valley: from Shimla via Kinnaur, or from Manali via the Atal Tunnel and Kunzum Pass. The route you choose has a major impact on acclimatization and the overall experience. The Shimla to Kaza route is longer (around 450 km) and takes 2-3 days, but it is highly recommended for first-time visitors. The ascent is gradual, which allows your body to acclimatize to the high altitude, significantly reducing the risk of Acute Mountain Sickness (AMS). This route is generally open year-round, weather permitting, though winter conditions can be severe. The Manali to Kaza route is shorter (around 200 km) and can be covered in a long 8-10 hour drive. However, this route involves a rapid and dramatic ascent to high altitudes, crossing the 4,590-metre Kunzum Pass. This sharp increase in elevation poses a much higher risk of AMS and is not recommended for those unaccustomed to high altitudes. This route is also seasonal, typically open only from June to October, as heavy snow closes Kunzum Pass for the rest of the year.
Navigating Road Status and Closures
The status of roads, especially high mountain passes, is the single most important factor determining your itinerary. The Shimla-Kaza highway (NH-5) is touted as an all-weather road, but it is susceptible to landslides during monsoons (July-August) and closures due to heavy snow in winter (December-March). The Manali-Kaza highway is entirely dependent on the opening of Kunzum Pass and, historically, Rohtang Pass. The Border Roads Organisation (BRO) works to clear the snow, typically opening the pass by late May or early June. As of late July 2026, the Manali-Kaza road is open. Even when open, the stretch from Gramphu to Losar is notoriously rough, with multiple water crossings that swell in the afternoon, making it a challenge for inexperienced drivers and smaller vehicles. Always check the latest road status a few days before you travel, as conditions can change overnight.
High-Altitude Survival Kit
Surviving and thriving in Spiti comes down to preparation. First and foremost is acclimatization. Whichever route you take, plan for a slow ascent, stay hydrated, and avoid over-exertion in the first 48 hours at a new altitude. Headaches and dizziness are early signs of AMS; if symptoms worsen, the only cure is to descend to a lower altitude immediately. Your packing list is crucial. Layering is key: pack thermals, fleece jackets, and a windproof/waterproof outer shell. Even in summer, nights are cold, and high passes are windy. A good medical kit should include basics for pain and stomach issues, along with any personal medications and possibly Diamox for altitude, after consulting a doctor. Finally, manage your expectations regarding connectivity and cash. Kaza has a few ATMs, but they are often out of cash or non-functional. Carry enough cash from Shimla or Manali to cover your entire trip. Mobile networks are sparse. BSNL and Jio have the best coverage in major towns like Kaza and Tabo, but most other networks are non-existent. Expect vast stretches, especially between Manali and Kaza, with zero connectivity. Download offline maps and inform your family about your travel plans before you go dark.
