In Jökulsárgljúfur National Park, the Jökulsá á Fjöllum River has created Iceland's longest river canyon, stretching over 25 km. There are several beautiful hiking trails through the park, starting at the Vesturdalur campsite. One tour leads to the red mountain cones of the Rauðhólar crater series, which offer excellent views over the canyon. Those who want to hike the three waterfalls of Jökulsárgljúfur can take the hiking trail above the canyon and pass the Hafragilsfoss, Dettifoss, and Selfoss waterfalls one after the other. With the establishment of Vatnajökull National Park in 2008, Jökulsárgljúfur National Park was incorporated into the larger park.

Réttarfoss is an impressive waterfall in northeastern Iceland, located in the Jökulsá á Fjöllum river. This river is fed by the Vatnajökull glacier and ends in the Arctic Ocean. The waterfall is about 12 meters high and 75 meters wide. The water of the Réttarfoss squeezes through a narrow gorge with an average volume of 193 m³ per second. The waterfall has a complex configuration - the front is serrated, with an island in the center. If you measure the front, the waterfall is about 470 meters wide. It is a powerful waterfall on the muddy Jökulsá á Fjöllum stream. The area is part of the Jökulsárgljúfur (Glacier River Gorge), one of Iceland's four national parks since 1945.

From the tip of the rock island, around which the path loops, there is a beautiful view of the impressive Ásbyrgi rock formation, which was mythologically explained as the hoof print of Odin's horse. This 'Fortress of the Gods' (Ásbyrgi) is actually a part of the Jökulsá River gorge that has long dried out.

The immense Jökulsárgljúfur National Park, for example, was carved by the Jökulsá á Fjöllum River flowing from the Vatnajökull glacier.
