If you have more time, you can add a visit to Kiliyur falls, which is around 3kms away from Yercaud. For food, try the local delicacies like the yummiest "Dosas in Salem", a street dosa joint. For a change of itinerary, remove Grange Estate and visit Ladies' Seat, a beautiful viewpoint on a cliff-top opposite to Shevaroy temple, offering a stunning view.
