We visited Nandi hills yesterday(23-Oct-2015), and it turned out to be the worst nightmare for me and my family. Its the worst road in my entire life I have seen so far. As a norm, Karnataka roads are worst in India, but this surpasses that "worst" definition.
If you want to test your CAR and spoil your CAR tires then this is certainly a good choice to go for. They charge Rs. 100 for parking, and do not have roads maintained. There is nothing to see at this place, its just few scenic view. Also, the entire place is very dirty. Every where we found garbage. In my view, this place doesnt deserve any star. I will not recommend any one to visit this place.
