When considering a trip to the Atal Tunnel in Manali, Himachal Pradesh, India, timing is crucial due to the region's distinct seasons greatly influencing the travel experience. The best time to visit Atal Tunnel is typically from May to October. During these months, the weather is mostly pleasant, facilitating easier passage through the tunnel and allowing travelers to enjoy the picturesque landscapes of the surrounding areas. Summer, spanning from May to June, offers a relief from the intense heat of the plains, making it a popular season for tourists. The temperatures range from a comfortable 10°C to 25°C.
Post-summer, between July and August, can be challenging due to the monsoon season. Heavy rainfall can lead to disruptions like landslides and road blockages affecting accessibility to the tunnel. Hence, it's crucial to check the weather forecasts and local conditions before planning your journey. By contrast, the autumn months of September and October are considered ideal for visiting the Atal Tunnel.

This period offers excellent visibility and the lushness of post-monsoon landscapes, making for a memorable drive through the tunnel. However, remember that the region begins to cool down rapidly as winter approaches, so pack accordingly.
