2 days ride among the plateau and lava fields above Husavik, toward 2 of the most scenic landmarks of the Diamond Circle. From Húsavík it climb on asphalt to the first trail near the geothemal power station. The trail last for a long time after that, through the wild and ruff landscapes to the lava field of Krafla eruption back in 1984.
After crossing Krafla lava field, the trail reach the main road and goes to the trails along Jökulsá á Fjöllum to Dettifoss. From there many difficult sections where you have to carry and hike the bike, but the view is spectacular over the canyons. The trail follow the river to the North until the campsite of Ásbyrgi. The next day you can choose between the highlands ruff roads or the coastal road to go back to Húsavík.
