Hveravellir Highland Traverse F35

Highland crossing between glaciers with hot springs

Moderate

The F35 Hveravellir route cuts straight through Iceland’s uninhabited highland interior between Langjökull and Hofsjökull glaciers, passing the famous Hveravellir geothermal area where natural hot springs steam against a backdrop of black volcanic sand. This 165-kilometer highland track includes multiple river crossings at Hvítá and Seydisá rivers, plus the notorious Blöndulón reservoir crossing that’s claimed more than a few rental cars over the decades.

Moderate difficulty requires high-clearance 4WD and river crossing experience — water depths can change dramatically with weather and glacial melt. Best tackled June through September when highland roads officially open, though early season means deeper fords. No fuel available on route, so carry extra jerry cans. The payoff is pure Iceland — otherworldly landscapes, zero cell service, and those therapeutic hot springs at Hveravellir hut for soaking road-weary bones.

Frequently asked questions

Can a stock Land Cruiser or 4Runner run the F35, or do I need a lifted rig?

A stock high-clearance 4WD handles it in normal summer conditions, but the river fords are the wildcard — water depth changes fast with glacial melt and rain. Snorkels aren't required, but knowing your vehicle's wading depth before you hit a crossing is non-negotiable.

When does the F35 actually open and close each year?

Typically opens late June and closes in September, sometimes earlier if autumn storms hit. Check road.is the day you plan to drive it — Iceland's Road Administration updates highland road status in real time and closures happen with little warning.

Do I need a permit to drive the F35 or camp along it?

No permit required to drive the route. Dispersed camping is allowed in Iceland's highlands, but you must camp at least 100 meters from water sources and pack out everything — no fire rings, no trace.

What's the hardest part of the F35 and what should I actually expect?

The glacial river fords are where moderate turns real — multiple crossings with no bridges, and water levels can jump significantly after a warm day or rainfall. Get out and walk the crossing before you commit, and cross at the widest, shallowest point, not where the track goes in.

Is there any fuel or resupply between Selfoss and the northern end of the route?

No. Hveravellir has a staffed hut and basic services mid-route, but don't count on fuel there. Carry enough range for the full 102 miles plus a buffer — the nearest reliable fuel is in Selfoss to the south or Blönduós to the north.
