One fine day my friend asked if I want to go Kerala? Then ? We booked our tickets on the same day for God's own country. The trip was planned in very short time, and I think that was beautiful part.We decided to visit Cochin, Allepey and Munnnar.
P.S. its advisable to learn little of Malayalam as not all people know English/Hindi. I got saved by my friend as she can understand and speak Malayalam.
