Road after left is not so bad. You pass through grape yards and will often see people selling grapes on slower corners / patches of the road. Nandi hill is the highest point in Karnataka; roads however are not so tough to drive up.
On top it’s a guest hours (not operational) surrounded by really bad garden and a ring road to this garden. Mountain is rocky and has a peripheral wall sort which is broken and most places. You also see a Ganesha temple, again not maintained well, police post and a post office. Place is full fruit vendors. You don't really have good food options on top so better carry your own tiffins.
Travel Time – Maximum of 1 hour from Hebbal flyover
Stay Time – Anything between 2 to 5 hours
Preferred hours – Try reaching early. This way you can avoid city traffic. Generally at noon, temperature on top is not so pleasant. Try reaching latest by 10:00 AM, have fun followed by food then start back after noon.
Approximate Budget - Around Rs 300 for a family of 2 + 1
What can be added – lots. Professional rock climbing and tracking can take this hill to new heights. Few good restaurants and cleanliness is badly needed.
Suggestions – carry your food do not depend on local eatables. Be careful of monkeys especially if you have infants or young kids. Carry a mat, drinking water along with food. Prefer a group of 4 and more.
Avoid – When in bad mood or when climate is not so good, i.e. its raining or its hot.
