One of the most iconic high-altitude road journeys in the country, the Manali to Leh drive is a 475 km-long journey. This road is typically open from June to September. This road takes you through several high-altitude mountain passes such as the Rohtang Pass, which is now avoided through the Atal Tunnel, Baralacha La Pass, and Tanglang La Pass. Because of the high elevation, which is typically above 4,000 meters, it is important to acclimatize.
