What does the author refer to as ‘bonus’? Why?
As one climbs the high hills of Brahmagiri, he gets a panoramic view of the entire landscape of Coorg. Walking a little more across a rope bridge, he is pleased to find the sixty-four acre island of Nisargadhama. The largest Tibetan settlement at Bylakuppe is a surprising bonus. The author calls it a bonus as it is the least expected here.
