Moderate to good fitness—able to do several short hikes on uneven ground and tolerate long vehicle rides.
Cross braided rivers and black-sand deserts aboard a private 4x4 to reach Askja’s vast caldera and the turquoise Viti Crater. This full-day highlands tour blends off-road driving, short hikes and geology-rich vistas best taken with sturdy boots and layered clothing.
You step into the day before dawn, headlights cutting through low cloud as the 4x4 grinds away from the shores of Lake Mývatn. The road narrows, then disappears into an expanse of black sand and pumice; rivers braid across the track and the land takes on a lunar bluntness. Your guide eases the vehicle across a shallow ford, and the engine’s steady thrum becomes the soundtrack for a day of geological extremes.

Weather in the highlands changes quickly—bring a breathable base, insulating mid-layer and waterproof outer shell.
Expect uneven lava fields and river-bank walking; ankle-supporting, waterproof hiking boots make short hikes safer.
Swimming in Viti is allowed only when guides confirm safe temperatures and calm winds—don’t assume it’s always possible.
Cold saps batteries and the landscape invites long shooting sessions—carry spare batteries and extra memory cards.
Askja’s 1875 eruption reshaped northern settlements and spread ash across Europe; the caldera formed when the volcano’s roof collapsed after major activity.
The highland ecosystem is fragile—stick to marked routes, avoid off-trail driving and follow Leave No Trace principles to protect moss and spring habitats.
Protects ankles across lava, gravel and wet river banks.
Wind and sudden rain are common; layers keep you warm and dry.
Carry at least 1–2 liters of water, lunch and emergency layers for stops.
Optional for a summer dip in Víti when guides confirm conditions are safe.
