Markarfljótsgljúfur Canyon is a hidden gem in Iceland's Southern Highlands, tucked away from the crowds. While not as popular as other canyons, it boasts stunning views and a deep gorge that plunges 200 meters down. The canyon was formed by a historic eruption of the Katla volcano, creating a unique landscape with the Markarfljót river flowing through it. Accessible via a challenging mountain road, this canyon is a must-visit for hikers on the Laugavegur trail or adventurous travelers looking to explore off-the-beaten-path destinations in Iceland.
