I have visited many tourist places in plains as well as hills. The hill stations are Srinagar (Kashmir), Simla (H.P.) and Shillong (Meghalaya). I have also visited Goa. I like sea more. Hence, the beaches of Goa especially Donna Polla spot appear most beautiful.
I have visited many places in India, but i haven't visited Kashmir, I think that is the most beautiful place in India. Many other countries are also very beautiful
Being a native of Kerala I hadn't seen any place that is better than mine.I don't have a visit to Kashmir so far and don't know will change this opinion.
