Santorini is an amazing and interesting place. The small townships on the island are all built around the rim of a extinct volcano which provides a spectactular view of the regions waters and the inner crater area. The sea entered the crater at a time when the craters edge was destroyed but now provides this amazing setting.
Another pre-arranged pickup seemed to work well and we headed off to the Athens Port to meet our ferry. Now that's a ferry!!! We were unceremoniously dropped at the back of the giant ferry wondering if that's where we were meant to be! Dragged the bags (had left one big one back at the hotel) up the gang plank onto the car loading ramp (still wondering what was going on!!), but found a rack to heave our big bag into then asked one of the car loaders where to go - through that door (an EXIT sign) and up the steps - okay!
