Booked this trip with a group of friends.  Had a super day.  Captain knew some great spots to stop at.  Had fun on mud beach, covering ourselves with white mud then washing it off in the clear blue sea. Swam into some beautiful caves where the light shone through like diamonds.  Sea was like silk, so clear ad blue.  Loutro is very quaint and you are able to do a bit of shopping or sample a refreshing ice-cream.  Would highly recommend.
