If you wish to catch the scenic valleys, the best time to visit the place would be before 2PM. But if you want to watch snow-like clouds (only in winter) beneath you form an ocean, reach the place between 3PM and 6PM. Try to catch the sunrise here or in the nearby Greenlands Hostel. At evenings a view of the Jewel Box (evening view of Theni and Periyakulam)is also an attraction. A marvel. Also try out the telescope near the main gate. This place is very near the bus stand.
Kodaikanal Lake
If you are going in winter, go boating in the evening, as it's an amazing experience to boat through fog settling on the lake. The lake is very near the bus stand. This is a star-shaped lake and walking around it during the night is one of the best walking experiences you can have in your life. Be cautious, there are lot of dogs around this lake and some places are extremely dark. Walk between 6 and 7PM, then head back to your room.
To reach Dolphins Nose at a distance of 8 km from the bus stand, one has to follow the route specified here. There is an old road after crossing Pambar Bridge near Levinge Stream. A rough curve rounds the hillside which leads to a point where a flat rock projects over an awful chasm of 6600 feet deep. This is Dolphins Nose. On the way, beautiful views of plains and steep, rocky escarpment called rolling hills can be seen. The old village of Vellagavi can be reached through the rugged bridle path.
