Kvernufoss waterfall is a hidden gem in South Iceland. The hike to the waterfall is only 20 minutes and easy, with some loose gravel and a couple of rocky areas. But it's worth it! The waterfall is 98ft tall and breathtaking to see, especially when you walk behind it in the summer. It's a mystical experience and I highly recommend bringing a raincoat as it can get a little misty. Don't miss this beautiful and unique waterfall, it's a must-visit!
