This is one of the 2nd largest backwater lake in india. It's situated near ponneri(TamilNadu).We can have a long drive in boat with life jackets and also can swim in the backwaters. Small family trips can be planned there. Bachelors party's can be had there(Personal experience).
I have been there twice and that was great to be there. Hope this may help u guys.
