The months of August and September are the best time of the year to enjoy the athirampilly, vazhachal and the charpa waterfalls because the light conditions are perfect as it is the fag end of the monsoon rains and the water is really falling through because the dams are open due to surplus water in the catchment area. We went by car to the athirampilly falls near chalakkudy. It was around an hour's drive from Kochi. Could capture some good photographs of the forest and the waterfalls. Spent maximum time at the charpa falls trying out slow shutter using nd filters and the tripod...after a long time.
