A definately 'must do' if you get to Sri Lanka. We really didn't know what to expect so we were quite nervous but the sea was kind to us today (unlike the following day......dear lord above!) and soon the sight of Blue Whales overtook any bad thoughts of the sea. We spent a couple of hours with these, but never getting too close, our skipper knew exactly what he was doing and could read the water perfectly. We can still hear the sound of the 'blow' and felt so privileged to see.
