The Diamond Circle in 3 days

Source updated September 2026 · Checked by Sóley on 12 October 2026

Starting and ending in Akureyri, this northern loop runs about 320 km, around five hours of driving spread over three days. Day one goes to Goðafoss and on to Lake Mývatn by the south shore, with the pseudo-craters at Skútustaðir, the lava formations of Dimmuborgir and a night by the lake. Day two is the longest: the steam vents at Hverir, Dettifoss from the paved west side on road 862, the twisted basalt at Hljóðaklettar, the horseshoe canyon of Ásbyrgi, and the Tjörnes coast to Húsavík. Day three is whale watching on Skjálfandi bay in the morning and an easy hour back to Akureyri. The loop is paved throughout; some short spurs to sights are gravel. Fill the tank in Reykjahlíð, as there are no fuel stations from Mývatn to Ásbyrgi. Stay behind the ropes at Dettifoss. In winter road 862 is not always cleared, so base yourself in Akureyri or at Mývatn and check the roads each morning.
