If you are planning on visiting the temple, here are some tips:
This temple itself is a great architectural piece of art. Spend some time exploring the temple. You can see that the inside pillars are fresh as they were hundreds of years back because they were hidden from degradation by nature.
Please plan your trip in such a way that you can spend some time exploring the physical and spiritual beauty of the temple because the inner temple was constructed around 5th century and the outer temple was constructed in the 12th Century by the Chola kings and the Vijayanagara kings. Vayu is incarnated as Lord Shiva and worshiped as Kalahasteeswara.
