Kvernufoss waterfall in South Iceland is a hidden gem that often gets overlooked by tourists, despite its stunning 98-foot cascade down lava rock cliffs. Located near the popular Skogafoss waterfall, Kvernufoss offers a quieter and more intimate experience for those willing to take the short hike to reach it. With the option to walk behind the falls and capture some amazing photos, this lesser-known spot is perfect for travelers looking to escape the crowds and immerse themselves in Iceland's natural beauty.
