hi! All the places listed by sharon are in Kerala. You can check out allkeralatours.com wherein u can go thru the hill stns, beaches etc in kerala. There are suggested itineraries which offer you a variety of tours(ayurveda, short tour, backwater tour etc). You can also check out tourskerala.com wherein they have a bookingform which has a no. of places listed where you can choose whichever u want 2 see, and just submit... They will be back with an itinerary and other details... MUST see places are Kovalam which is 15 km frm Trivandrum (capital city), Munnar (tea plantations-TATA), Thekkady (wildlife sanctuary). You can come down 2 Tvm, do sight-seeing and stay in a hotel in Kovalam(there are many budget hotels in and around kovalam) & enjoy the beach. There are a lot of ayurvedic resorts too...
And yes, to enjoy the backwaters of Kerala, you must take a ride in a houseboat. There are types of accommodation in a houseboat. These rides are avlble in Allepey, don\'t know how far it is from Tvm... Let me find out...
I have also heard abt a place called Kuttanad in Kerala where farming is done below sea-level... But don\'t know where exactly... Anyways, will try to get u more info. Bye.
