Polonnaruwa was phenomenal. The ruins were extensive and it took all day to wander through and see everything. This was definitely the highlight for me so far. The rest were interested, but perhaps wouldn't have explored for quite so long. I kept bugging Kate (who is in charge of the cameras), 'are you filming this?', 'don't get the tourist in it, I just want ruins'. I'm sure she's quite sick of me.
They really were incredible. I could spend days wandering through.
