Stuðlagil Canyon, located in East Iceland's Glacier Valley called Jokuldalur, is a hidden gem with the largest number of basalt rock columns in Iceland. Formed by a powerful glacial river, the canyon offers stunning views of blue-green waters and unique geological formations. Despite its remote location and lack of facilities, visitors can enjoy hiking trails and the beautiful Studlafoss waterfall nearby. **This is best visited in the summer months, as it is difficult to drive to in the winter months with unpredictable weather patterns**
