Dear Student, 

I am assuming you are asking why the climb to Brahmagiri is an important part of the visit to Coorg.

Here is your answer :

The Brahmagiri hills give you a panoramic view of the entire landscape of Coorg. Therefore, the climb to Brahmagiri is an important part of the visit to Coorg.
