Looking incredulously at the sky on a cold winter's morning in Dublin, I was tempted to believe I was seeing the Northern Lights. I knew it was too good to be true. It turns out that what I was really seeing was a phenomenon called 'rainbow clouds' or cloud iridescence. The combination of morning sun riding low in the winter sky and small ice crystals in the clouds diffract the light to create a rainbow effect. As you can see, the result is truly stunning.

We encountered the rainbow clouds on a morning walk through Ballsbridge. As VacationCounts advocates, it's a great idea to turn a part of every day into a mini-vacation. Our morning walks epitomize this.
