Have you eve seen a canyon so beautiful? Fjaðrárgljúfur is a canyon in south east Iceland that's known for its breathtaking beauty. It's up to 330 feet deep and about one-and-a-quarter kilometers long, with a river called Fjar flowing through it. Created by a progressive erosion of flowing water from glaciers through rocks, the canyon has been hallowed out for millions of years. The walking path along the eastern edge offers stunning views over both the plains and the glacial brooks below. Here are some of our favorite photos of the must-visit destination.
