Fjaðrárgljúfur Canyon, located in South Iceland near Kirkjubæjarklaustur village, is a stunning natural wonder that stretches for 2 kilometers with cliffs rising up to 100 meters high. After gaining fame from Justin Bieber's music video, the canyon was temporarily closed due to overtourism but has since reopened with improved infrastructure. Visitors can enjoy breathtaking views of the canyon and Fjadra River from designated trails, making it a must-visit spot for nature lovers and photography enthusiasts alike.
