I haven't been to the area you're interested in but if you're still mulling over your options and haven't got a flight yet then consider going to the Andaman Islands instead, I was there 11 years ago and although it's probably changed a lot it'll still be a special part of the world.
You can get a flight from Chennai to Port Blair or a boat from Kolkata, our boat took about six days due to a storm but it's usually less.
Then check out Havelock Island, I spent a month there with some pretty cool people from all over the world, including very chilled locals.
Some other islands let you camp out and go 'wild'.
It's a completely different India, might not be what you're looking for but worth a read.
