In the afternoon we set off for the Blue Grotto. You have to pay locals to take you in via these little row boats. When it's busy you have slip them something to "move you to the front of the line" or you can wait for hours. We waited until mid afternoon to try to miss all the crowds which worked, but we go the just before they all pack up and went home. They ran you in and out, so I didn't get time to get the camera setup so there aren't really good shots from inside. The color was pretty awe inspiring, but you're time is limited and you're under the control of the guy with the oars.
