G - where did you stay? what part where you in?
We were all over the coast - we took a train into Trivandrum first and spent 2 days there. I think Kovalam Beach is there - very beautiful and lots of resorts and things to do there. Then we went did a driving trip to Thekkady, Munnar, and Alleppey. I think it was in Alleppey where we took an overnight houseboat - just the two of us on this big houseboat with a crew of 3 or so. They steered the boat down the river and cooked us dinner, lit a fire for us, we just sat and watched the river and the sunset, had some drinks and dinner...it was amazing. Very peaceful and relaxing - I would recommend anyone do this if they can!! Then we went to the tea gardens in Munnar, which is like a hill station, and the wildlife sanctuary in Thekkady (I think it was there). I think we flew out of Cochin eventually?
I think Trivandrum is where you are at the very tip of India and on one beach you can see the sun set in the evening over the horizon and then see the sun rise in the morning over the same horizon...amazing experience.
