The ideal duration for a Spiti Valley road trip depends on your preferences and the places you want to explore. A comprehensive trip covering the major highlights like Key Monastery, Chandratal Lake, Pin Valley, and Kaza typically takes around 7-10 days. This allows for a more relaxed journey, acclimatization to the high altitudes, and exploration of remote villages.
However, if you have limited time, a shorter 4-5 day trip from Manali to Kaza and back can provide a glimpse of Spiti’s beauty. For a more immersive experience, especially if you plan to include trekking and cultural experiences, extending your trip to 12-14 days or more is advisable.
