Seljalandsfoss is one of the most beautiful waterfalls in Iceland. Dropping from a 200-foot-high cliff to a deep pool below, this unusual waterfall of the Seljalandsá River has a unique indentation in the rock face that allows visitors to hike behind the picturesque falls. Lush greenery and a wide variety of colorful wildflowers surround the falls. As photographer Mike Reyfman describes, "Getting in touch with the natural wonders of Iceland can be a very exhilarating and enlightening experience. Located along the south coast is one of its most breathtaking waterfalls. To take a panoramic capture of the Seljalandsfoss, a photographer must be prepared for the intense mist and huge dynamic range."
