Travel 26 km (16 mi) from Grímstunga I to reach Iceland’s largest glacial river, Jökulsá á Fjöllum. 10 km west of the river is a road that will take you along the river to the canyons Jökulsárgljúfur, via the northern-most part of national park Vatnajökulsþjóðgarður. Europe’s most voluminous waterfall, Dettifoss, guarded by a majestic row of cliffs, is about 24 km / 15 mi away and is easier to see from road 864 (east side of the waterfall). Also other waterfalls are worth seeing; Selfoss is a little further up the river from Dettifoss, and Hafragilsfoss is a little further down the river. There are many marked hiking routes in this area, and you can also join organised guided tours that depart from village Reykjahlíð.

Suggested Trips

Trip to Mývatn, total driving time about 2 hrs.

Go to Mývatn and see Hverfell, a large, circular explosion crater, about 140 metres deep and with a diameter of 1,000 metres. Hverfell is one of Iceland's most beautiful and symmetrical explosion craters, besides being one of the largest of its kind in the world.

Next Dimmuborgir, a large area of unusually shaped lava fields. The area is composed of various volcanic caves and rock formations, reminiscent of an ancient collapsed citadel.

The trip around the lake is worth taking, at the north end is one of the most beautiful rivers in Iceland, Laxá í Aðaldal.

Krafla powerplant and the surrounding area of volcanic craters and mountains is surreal, a must see.
