F88 Mývatn to Askja: 200 km 4×4 Desert Drive, Summer Only

Askja is a remote volcanic caldera deep in the Vatnajökull National Park highlands, holding the vast Öskjuvatn lake and the milky-blue Víti crater you can bathe in. The classic way in, the F88, crosses the black Ódáðahraun lava desert and fords glacial rivers — the Lindá can be impassable after rain. This is strictly a large-4×4, summer-only route, and the final stretch to the crater is a 2.5 km walk. You drive on the right.

Day 1 — Mývatn to Askja and back (200 km round trip)

Leave the Ring Road east of Mývatn onto the F88, striking out across the lava desert under the Herðubreið massif. Ford the rivers carefully, reach the Vikraborgir car park, and walk in to the caldera rim above Öskjuvatn, then down to Víti for a soak if conditions allow. Return the same day — start early, as the drive is long and slow and the rivers rise later on.

Costs

Use the cost calculator to price fuel and the day for your exact dates. Budget a large 4×4 and plenty of fuel (there is none in the interior), or take a guided super-jeep tour from Mývatn or Akureyri, which is the safer option and reads the river levels for you. There are no tolls. Check road.is that morning, never rush a ford, and turn back if the Lindá is running high.

This trip is also in the free Roadcut trip planner: change the number of days and where you sleep each night, pick your vehicle to see the fuel cost, check the weather on the road, and open each day in Google Maps, Apple Maps or Waze.
