At the northern end of Vatnajökull National Park, the lush canyon Ásbyrgi (pronounced ows-beerg-ee) extends in a massive horseshoe shape, measuring 3.5km from north to south and averaging 1km in width. From the car park at the end of the access road, 3.5km south of the visitor centre, several easy short tracks lead through the forest to viewpoints of the canyon. Heading east the track leads to a spring near the canyon wall, while the western track climbs to a good view across the valley floor. The trail leading straight ahead ends at Botnstjörn, a small bird-friendly pond at the head of Ásbyrgi. There's also a signposted loop trail showcasing the area's flora.
