Castle Stalker, Argyll, Scotland
Castle Stalker, near Appin, is one of the most photogenic castles I've ever seen. I parked near the shore and donned a pair of rubber boots so I could walk out into the shallows. The morning wasn't that great, but with typical suddenness for the Scottish coast the sky cleared, only to be followed by a sudden rainstorm, which cleared just as quickly and left behind a rainbow over the castle. Talk about perfect timing!
