I read that the best time to see the Charles Bridge here in Prague was at dawn because there would be no people around.
Therefore, this morning, I was up early, left the hotel at 6:00 and and walked down to the bridge. There was just a trace of light in the sky when I arrived and I walked out onto the bridge where I found another five people with the same intention of taking some photos at dawn.
Well it was certainly worth the effort. Not only did we have the bridge to ourselves, there was a beautiful red morning sky that offered great lighting for photography
