A Telescope House has been installed near Yelagiri Hills to attract visitors. It is maintained by the Forest Department. The telescope House is at the entrance of the Ghat Road from Ponneri on the way to Yelagiri Hills. It is located just before the thirteenth bend, at a height of 1002 metres.
The telescope provides a panoramic view of the plains below. It enables the tourists to have a view of the valley, the steep slope, the Jolarpet plains and the Vaniyambadi. The telescope house is supposed to be open on the weekends but more often than not one can find a Padlock.
