Jökulsárgljúfur is the northernmost part of Vatnajökull National Park, with separate boundaries, but geographically connected to the rest of the park by the glacial river Jökulsá á Fjöllum. The river's source is in Vatnajökull glacier, near the subglacial volcano Bárdarbunga.
Jökulsárgljúfur literally transcribes as Glacial-River-Canyon. This canyon is 25 km long, 500 m wide and in many places 100-120 m deep, making it one of the deepest and most breath-taking canyons in Iceland. Jökulsárgljúfur is also known for its series of waterfalls: Selfoss, Dettifoss, Hafragilsfoss and Réttarfoss.
The park's visitor centre is located in Ásbyrgi. A fairly large and developed campground can also be found in Ásbyrgi. A more primitive campground is located in Vesturdalur, which is midway between Dettifoss and Ásbyrgi.
Ásbyrgi can be visited any time of the year, although services may be limited during winter. Dettifoss and Vesturdalur are located at higher altitudes and therefore subject to snow cover and road conditions.
