Coaker's Walk is a 1km paved pedestrian path running along the edge of steep slopes on the southern side of Kodai. The walk, winding around Mount Nebo providing a stunning panoramic view of the plains. On a clear day one can view as far as Dolphin's Nose in the south, the valley of the Pambar River in the southeast, Periyakulam town and even the city of Madurai. A fascinating rare phenomenon called Brocken spectre can be witnessed, when a person can see his shadow on the clouds with a rainbow halo. This occurs when the sun is behind the viewer and clouds and mist are to the front. There is an observatory with a telescope halfway along the walk.
