Spiti Valley Full Circuit Road Trip Guide: Route, Permits & Map

Introduction to the Full Spiti Circuit Expedition

The Full Spiti Circuit is one of the world's most dramatic overland road journeys, forming an epic loop of over 1,200 kilometres through the northern Himalayas of Himachal Pradesh. Encircling the jagged trans-Himalayan mountain barrier, the route takes you from the forested apple valleys and colonial hill towns of Shimla, through the vertiginous cliff-carved gorges of Kinnaur along the historic Hindustan-Tibet Highway (NH5), across the desolate, moon-like high desert of Spiti, over the glaciated ramparts of Kunzum Pass (4,590 metres), and out through the alpine forests of Manali. If you are beginning your planning from a foundational perspective, our comprehensive Spiti Valley travel guide offers an essential introduction to the region's geography and culture.

A successful self-drive expedition across Spiti demands more than just passion for the open road; it requires strategic route selection, understanding high-altitude physiology, navigating extreme terrain, and managing essential logistics like fuel, permits, and communications. For pre-departure preparations, review our Spiti Valley road trip checklist to ensure your vehicle and emergency gear are thoroughly prepared.

Why You MUST Drive Anti-Clockwise: The Golden Rule of Acclimatization

The most crucial tactical decision on the full Spiti circuit is your direction of travel. Seasoned Himalayan expedition leaders and physicians universally recommend driving anti-clockwise: entering via Shimla / Kinnaur and exiting via Kaza / Manali.

The Physiological Science Behind the Direction:

• The Shimla Approach (Anti-Clockwise): When you start from Shimla (2,200m), your elevation increases gently over 4 to 5 days: Narkanda (2,708m) → Sangla/Kalpa (2,960m) → Nako/Tabo (3,280m) → Kaza (3,800m). This gentle, stepwise ascent allows your respiratory and circulatory systems to adapt naturally to lower atmospheric oxygen levels, dramatically reducing the risk of Acute Mountain Sickness (AMS).
• The Manali Approach (Clockwise - The High Risk Route): If you enter directly via Manali (2,050m), passing through the Atal Tunnel places you at Kunzum Pass (4,590m) within just 4 to 5 hours of driving, sleeping at Kaza (3,800m) on Night 1. This massive 1,800-metre altitude leap in a single afternoon frequently triggers severe altitude sickness, debilitating headaches, nausea, and potentially life-threatening pulmonary or cerebral edema.

Comprehensive Full Circuit Itinerary (9-10 Days)

This master schedule strikes the perfect balance between driving safety, daylight management, and immersive exploration of Spiti's cultural treasures.

Day 1: Shimla to Narkanda / Sarahan (130 km - 165 km | 4 - 6 hours)

Leave Shimla behind, driving along NH5 past dense pine woods to Narkanda. If time permits, continue to Sarahan (2,165m) to visit the extraordinary 800-year-old wooden Bhimakali Temple, an architectural masterpiece dedicated to Goddess Durga.

Day 2: Sarahan to Sangla & Chitkul (120 km | 5 hours)

Descend to the Sutlej river gorge and enter Kinnaur district through the iconic cliff-carved rock tunnel at Tranda Dhank. Branch off at Karcham into the enchanting Baspa Valley to stay in Chitkul (3,450m), the last inhabited Indian village near the Indo-Tibet border.

Day 3: Chitkul to Kalpa / Reckong Peo (65 km | 3 hours)

Drive up to Kalpa (2,960m), perched on a ridge facing the sacred 6,050-metre Kinner Kailash peak. Explore local apple orchards, the ancient Hu-Bu-Lan-Kar monastery, and the Roghi cliff drop ("Suicide Point").

Day 4: Kalpa to Tabo via Khab & Nako (150 km | 6 - 7 hours)

Cross the confluence of the Spiti and Sutlej rivers at Khab, negotiate the winding Ka Loops to Nako Lake (3,662m), take the detour to the 500-year-old mummified Buddhist monk at Gue village, and arrive at the historic mud monastery of Tabo (3,280m). To understand the deep heritage of Spiti's high villages, explore our Spiti circuit villages guide.

Day 5: Tabo to Kaza via Dhankar Monastery (65 km | 3 - 4 hours)

Visit the cliffside ruins of Dhankar Gompa (3,890m) overlooking the Spiti-Pin river confluence. Arrive in Kaza (3,800m), check into your hotel, and obtain any required permits. For a monastic deep-dive, see our Kaza monasteries guide.

Day 6: High-Altitude Villages & Monasteries (80 km circuit)

Day drive covering Langza (fossil village & giant Buddha), Komic (4,587m, world's highest motorable village), Hikkim (world's highest post office), Key Monastery (4,166m), and the dizzying Chicham suspension bridge.

Day 7: Kaza to Chandratal Lake via Kunzum La (95 km | 5 - 6 hours)

Ascend the majestic Kunzum Pass (4,590m), offering views of the Bara Shigri Glacier—the second longest glacier in the Himalayas. Branch onto the 14km dirt track to Chandratal Lake (4,300m) and camp under a sky filled with millions of stars. For ideal seasonal timing, read our guide on the best time to visit Chandratal.

Day 8: Chandratal to Manali via Batal & Atal Tunnel (125 km | 6 - 7 hours)

Tackle the legendary off-road boulder trail along the Chandra River through Chhota Dhara and Gramphu. Pass through the 9.02km Atal Tunnel into Manali to conclude the grand high-altitude loop.

Essential Logistics: Permits, Fuel, ATMs, and Connectivity

1. Inner Line Permits (ILP)

• Indian Citizens: No Inner Line Permit is required for the full Spiti circuit. Simply carry valid government photo IDs (Aadhaar or Passport).
• Foreign Nationals: An Inner Line Permit is mandatory for foreign passport holders traversing the border section between Akpa/Jangi and Sumdo. Permits can be obtained from the District Magistrate / SDM offices in Shimla, Reckong Peo, or Kaza.

2. Fuel Availability & Management

• Reliable Petrol Pumps: Shimla, Theog, Narkanda, Rampur, Tapri, Powari (near Reckong Peo), and Kaza (the world's highest commercial fuel station at 3,740m).
• Critical Fuel Gap: There are no petrol pumps between Kaza and Manali (approx. 200km of heavy off-road driving in 1st/2nd gear). Fill your tank to capacity in Kaza.

3. ATMs and Mobile Networks

• Cash is King: While UPI works in Shimla, Reckong Peo, and Kaza town, carry ₹15,000 to ₹25,000 in physical cash for remote homestays, dhabas, and Chandratal camps. ATMs in Kaza frequently run out of cash or lose satellite links.
• Mobile Network: Jio and BSNL postpaid/prepaid connections provide the most reliable coverage across Kinnaur and Spiti. Airtel functions in major towns (Shimla, Reckong Peo, Kaza) but loses signal in remote valleys.

Vehicle Selection and Driving Techniques

While local Spiti drivers expertly pilot Maruti Altos across these passes, self-drive visitors should ideally choose an SUV or crossover with at least 180mm to 200mm of ground clearance (such as Mahindra Thar, Scorpio, Tata Safari, Toyota Fortuner, or Hyundai Creta). The Gramphu-Batal section features sharp unpaved rocks and deep water crossings where low-clearance sedans risk severe underbody impact. Drive steadily in lower gears, never ride the clutch, and always yield the uphill right of way to ascending mountain commercial traffic.

Conclusion

The Full Spiti Circuit is a masterclass in Himalayan overlanding. By following the anti-clockwise route via Shimla, pacing your elevation gains, preparing your vehicle for rugged terrain, and respecting the fragile high-altitude ecosystem, you will complete one of the greatest road trips on earth.
