Went for a weekend drive from the city, about 80km away. Nandi hills are about 1500meters above sea level, very near to new Bangalore International airport (BIAL), so the roads were very good. The view from the top of the hills is fantastic. Many monkeys are there fighting so don't carry any food with you otherwise they will catch it. Keep it in you car & locked. About 15 hairpins are to be negotiated to reach the top of the hill. There are some old temples and architectures. Below the hills you can farmers and their kids selling fresh gapes, we bought some to make some wine.
