If you're travelling Solo then, Bangalore-Mysore by Train
Mysore-Mangalore by train
Mangalore-Bandipur by Bus+Pvt Vehicles
Bandipur-Ooty-Coimbatore Pvt Taxis etc
Coimbatore-Alappuzha via train
Alappy-Kochin by any means (it's nearby) And if You're looking for a group travel then I think you must go for a Car, per head contribution would not be more than 10k-12k including food for a group of 4..
About transportation: I suggest you to hire a car so that it'll be easy for you to explore each destination.
if you have gang of 4 people than it's a best option to hire cab
which cost you 6k to 7k per head for entire trip which could be better than any other means of transportation. thanks..
