This is the aptly named Azure Window on the western side of the wonderful island of Gozo. Just back from 2 weeks holiday and we had a wonderful time. Gozo is part of Malta but a separate and much smaller island just a few miles to the west. Its population is about 25,000 and its largest town is called Victoria. I will post a few more from the trip but this is a shot from one of the more "touristy" sites on the island.
No fiddling with colours here, it was that blue. Used my 10 stopper and polariser.
