Still missed many. Kerala is a pot pourri. Cannot say a single place as the best. All are best.

Surely the answer depends on what type of tourist you are?

For me I enjoy visiting places of historical interest, I also enjoy fresh seafood, fishing and cool mountain air but often difficult to combine all.

sahabcse, may be an idea to outline what exactly you are seeking to allow the good people of this forum to better assist.
