The ideal time to visit Pillar Rocks in Kodaikanal is during the post-monsoon months from September to May. This period marks the transition from the heavy rains to a more pleasant climate, making it perfect for tourists to enjoy the panoramic views and lush greenery. The skies are clear, allowing for uninterrupted views of the three giant rock pillars standing majestically against the backdrop of dense forests. The temperature ranges from 10°C to 20°C, creating a cool and comfortable environment for sightseeing and photography.
Summer months, April and May, can be specifically highlighted as the peak tourist season due to the moderate climate, which provides a respite from the heat prevalent in other parts of India. Even though it might be slightly crowded, the daytime is sunny with cool breezes, and the evenings are generally cool, contributing to a pleasant outing. Additionally, the flora around the rocks is in full bloom, enhancing the beauty of the spot. However, visibility might be lower in the early morning due to mist, so it's advisable to plan your visit post-noon for the best experience.
