This is the place where I spent the most beautiful 6 months of my life, there are natural beauty, lakes, hills, temples water parks, Bannerghatta safari and many enjoyable things.All you need to explore things but no doubt the pollution is also there, sometimes language barrier creates a little inconvenience but there are many people who speak English and hindi very well so this happens less often.
Keep in mind that Bangalore is expensive place for people who live there so make your visiting plan according to your budget
