Jokulsargljufur Canyon

Background

History & Background

Jökulsárgljúfur was established as a national park in 1973 to protect the dramatic canyon system and its unique geology. According to Norse mythology, Ásbyrgi canyon was formed by Óðinn's eight-legged horse Sleipnir touching down with one hoof. Scientists believe the canyon and surrounding landscape were shaped by at least two catastrophic glacial floods from eruptions beneath Vatnajökull, the most recent about 2,500 years ago. The area merged with Vatnajökull National Park in 2008.

Jökulsárgljúfur canyon is a spectacular 25-kilometer-long and up to 120-meter-deep canyon carved by the Jökulsá á Fjöllum river, Iceland's second-longest river. The canyon was formed by catastrophic glacial floods (jökulhlaups) following volcanic eruptions beneath Vatnajökull glacier, with the most recent major flood occurring around 2,500 years ago. The area became part of Vatnajökull National Park in 2008, having previously been an independent national park since 1973. Key attractions include Dettifoss (Europe's most powerful waterfall), the horseshoe-shaped Ásbyrgi canyon with its lush birch forest, Hljóðaklettar (echoing rocks) with unusual basalt formations, and countless smaller waterfalls and rock formations. The entire area showcases the raw power of nature and Iceland's volcanic and glacial forces working in concert.
