Winter transforms Indian road trips. Rajasthan Golden Triangle (October to February): desert heat gone, forts in golden light. Winter Spiti (via Shimla): the most adventurous cold-weather drive, -25 degrees C at night, complete solitude. Coorg Coffee Country (December to January): mist over coffee estates, waterfalls at full volume. Varanasi Ganges Circuit: Dev Deepawali in November is unmissable. Kerala Backwaters Circuit: peak season with clear skies throughout.
