Asbyrgi certainly is one of nature’s wonders. It is a 3½ km long canyon with up to 100 m high walls occupied by fulmars during the breeding season. It is the northernmost part of the National Park Jokulsargljufur under the management of the Forestry Service.
The well vegetated area between the canyon walls is a very popular recreational area, especially among families, and local festivals are celebrated there. In its middle is a freestanding and precipitous rock called “The Island”. The canyon is partly wooded, mainly with birch, willow, larch and fur. It was created by two catastrophic melt-water flood waves from the icecap Vatnajokull far in the south, the first one about 8-10 thousand and the second about 3000 years ago.
