Starting with Shimla works best for travelers because it sits at lower altitude helping with gradual acclimatization. This sequence prevents altitude sickness issues that can occur when jumping directly to Manali's higher elevation. Shimla's colonial charm and easier terrain also provide a gentler introduction to mountain travel, especially for families with young children or elderly members.

The logistics also favor the Shimla-first approach since the return journey from Manali to Delhi is straightforward without backtracking. You progressively move deeper into the mountains, building anticipation for Manali's adventure activities and dramatic landscapes. This route ensures you save the best experiences like Rohtang Pass and Solang Valley for later in your trip.

However, if time is extremely limited or you are primarily interested in adventure sports, reversing the order works too. Tour operators recommend the traditional sequence for good reason. Planning your Shimla and Manali tour by car with Shimla first creates a logical flow that maximizes comfort and enjoyment throughout your mountain escape.
