Chapter I — The Legendary Overland Route
428 Kilometres Across Three Mountain Ranges
The **Manali-Leh Highway (National Highway 3)** is widely hailed by global overlanders and motorcyclists as one of the ultimate road trips on Earth. Stretching for 428 kilometres from the pine-scented orchards of Manali (in Himachal Pradesh) across the Pir Panjal, Great Himalayan, and Zanskar mountain ranges to the cold desert oasis of Leh (in Ladakh), the highway crosses some of the highest paved mountain passes in the world.
Originally constructed by the Border Roads Organisation in the late 1960s as a strategic defense corridor, the highway has undergone extraordinary modernization. The inauguration of the 9.02-kilometre **Atal Tunnel** beneath the Rohtang Pass in 2020 eliminated the notorious Rohtang mud chokepoint, reducing driving time by five hours and connecting Manali directly into the stunning Lahaul Valley.
Chapter II — Stage-by-Stage Itinerary
The Recommended 2-Day Drive with Overnight at Jispa
Attempting to drive the Manali-Leh Highway in a single continuous 16-to-18-hour day is dangerous due to driver exhaustion and rapid altitude gain. The highly recommended schedule is a **2-day journey with an overnight halt at Jispa or Keylong**:
Day 1: Manali to Jispa (140 km, 4–5 hours). Depart Manali, cross through the Atal Tunnel into Lahaul, drive past Tandi (fill fuel tanks to maximum!), continue past Keylong to Jispa (3,200 m). Jispa offers comfortable riverside hotels, Swiss tents, and a safe altitude for sleeping.
Day 2: Jispa to Leh (288 km, 8–10 hours). Depart early (5:30 AM). Climb past Darcha and Suraj Tal to cross **Baralacha La (4,890 m)**. Descend into the vast gravel riverbed of Sarchu (border of HP and Ladakh). Tackle the 21 hairpin bends of the **Gata Loops**, cross **Nakee La (4,739 m)** and **Lachung La (5,059 m)**. Descend through the spires of Pang, accelerate across the smooth 40-km flat runway of the **More Plains (4,800 m)**, conquer the monumental summit of **Tanglang La (5,328 m)**, and descend through the red-rock canyons of Rumtse and Upshi into Leh.
Chapter III — Crucial Fuel & Acclimatisation Rules
The 365-Kilometre Fuel Desert and Altitude Hazards
The most critical logistical reality of the Manali-Leh Highway is the **complete absence of fuel stations between Tandi and Karu**—a distance of nearly 365 kilometres over extreme high passes where engines consume roughly 30 percent more fuel due to thin air and steep gradients. Motorcyclists and vehicles must fill their tanks to the brim at Tandi in Lahaul, and carry supplementary metal jerry cans of petrol/diesel.
Regarding altitude sickness, **avoid sleeping at Sarchu (4,290 m) or Pang (4,500 m)** on your first night out of Manali. Sleeping at extreme altitude without prior acclimatisation almost always triggers severe insomnia, splitting headaches, vomiting, and high risk of HAPE. Sleeping at Jispa (3,200 m) provides the ideal physiological buffer before crossing the high passes the following day.

Essential Preparation, Routes & Rules
Critical Information for Travelers
- Season: Open typically from late May or early June through late October. Closed by heavy winter snow from November to May.
- Tandi Fuel Pump: Mandatory stop! Top up fuel tanks and fill extra jerry cans before proceeding into the high mountains.
- Vehicle Recommendation: High-ground-clearance SUVs, 4x4s, or sturdy motorcycles (Royal Enfield Himalayan, adventure tourers) are ideal. Paved asphalt covers over 90% of the highway, but rough gravel and water crossings exist around Baralacha La and Sarchu.
- Permits: Vehicles passing through Manali towards Atal Tunnel require an online Green Tax / Rohtang Pass permit if visiting Rohtang top. No Inner Line Permit is required for the highway itself until reaching Leh.
