How should you link Ásbyrgi, Dettifoss and Húsavík?
A practical one-day North Iceland driving route

Ásbyrgi and Dettifoss: choose a through-route or the same hotel

The easiest mistake when leaving Húsavík is to underestimate “see Ásbyrgi, then come back”. Húsavík to Ásbyrgi is about 130 km, roughly two hours each way in normal conditions; allow extra time for fuel, sheep, one-lane bridges and photo stops. The transfer from Ásbyrgi to the west-bank entrance for Dettifoss is another journey in the roughly 70 km range, with road conditions and season making a significant difference. After the waterfall, the return to Húsavík can use around five hours of driving by itself, leaving the canyon walks and lunch squeezed in between.

If Mývatn is already on your route, the through-route makes sense: see the canyon at Ásbyrgi, watch the power of Dettifoss, then sleep at Mývatn without retracing your wheels. The next day could take in Krafla Víti and Námaskarð/Hverir, or return to Húsavík via Route 85. For the difference between staying around Mývatn and Húsavík, read the comparison of Mývatn and Húsavík accommodation bases before committing to this route; that page deals with where to spend the night, while this one decides which way your daytime wheels should turn.

Three schedules, with the final driving leg as the main difference

Through to Mývatn: Leave Húsavík at 07:30 and aim to reach Ásbyrgi before 10:00. Allow 90 to 120 minutes for a short walk and canyon viewpoints; bring lunch, as supplies along the route are limited. Continue to Dettifoss on whichever roads are open, allowing two hours for parking, walking and photographs. You may not reach Mývatn until evening, so do not plan a bookable activity after check-in. If Route 862 is closed, turn back or use a road whose opening has been confirmed; a straight-line distance on a map is not a substitute.

Ásbyrgi return trip: This is the version I would give a first-time North-East visitor who does not want the whole day handed over to the car. Choose one short canyon walk, start with a viewpoint over the horseshoe-shaped landscape, then extend it if your energy and time allow. The guide to short walks versus a full day at Ásbyrgi can help you choose how long to stay. Back in Húsavík, if whale watching is booked for the next day, keep the evening to dinner near the harbour and rest; do not add a distant viewpoint simply because you are already there.

Northbound from Mývatn: If you slept at Mývatn, Ásbyrgi and Dettifoss can become a northbound side route, but the final accommodation matters. If you need to reach Húsavík for an afternoon activity, count back at least two hours from the in-town meeting point; the whale-watching meeting time is not the same as sailing time, because check-in, warm clothing and parking come first. Read the choice between horse riding and whale watching in Húsavík before fixing the day: treat the sea trip as the fixed anchor, while the outdoor waterfall stop is the part you can shorten.

How to read Route 85 and Route 862

Route 85 follows the northern coast and the edge of the North-East, linking Húsavík towards Ásbyrgi and forming the backbone of this route. Route 862 leads to the west bank of Dettifoss; the attraction has the same name on both sides, but the entrance and road experience differ. Do not interpret “the west bank is easier” as a year-round promise: spring thaw, the first snow in autumn and winter accumulation can transform a side road. On the day, check road conditions, the forecast and daylight together, then put the latest information back into your driving order instead of checking once at night.

Even in clear summer weather, watch for gravel and slow vehicles. A photo stop that sounds like five minutes can become twenty, especially when a canyon, seabirds or horses appear. If luggage is in the car, keep larger items low in the boot on a transfer day, and do not leave cameras or passports visible when stopping at an isolated viewpoint. These small habits do not improve the scenery, but they mean you will not have to reorganise the car before the next stop.

Seasonal planning: the real dividing lines on this route

June to August brings long daylight, giving Ásbyrgi’s paths and Dettifoss more breathing room; the trade-off is that popular whale-watching departures and accommodation fill faster. From September, low morning and evening light can suit the canyon, but wind, rain or snow and less usable daylight make a Húsavík return harder than in summer. In May, during the thaw, do not look only at the temperature: check mud on side roads and whether car parks can be used.

Between November and April, I would not present Ásbyrgi, Dettifoss and Húsavík as a fixed one-day route. When a storm reaches the north, protect the main roads and the return to your accommodation first. For alternative winter bases in North Iceland, read the winter base choice between Húsavík and the North-East coast. If the waterfall is the priority, the choice between Goðafoss and Aldeyjarfoss is often easier to fit into an itinerary whose roads are confirmed open; you do not need to venture down a side road for a waterfall with a similar name.

Free attractions still carry real costs

Ásbyrgi canyon and Dettifoss generally do not charge a bath-style admission fee, but the day still costs fuel, long hours behind the wheel, time spent dealing with wet shoes and socks, and the opportunity cost of missing a booked meeting. For two people travelling from Húsavík through to Mývatn, estimate fuel from the vehicle, the day’s fuel price and total kilometres. Rather than writing a fixed figure that will expire, use the route distances as a planning frame: Húsavík to Ásbyrgi is about two hours, Ásbyrgi to the waterfall is roughly a one-to-two-hour transfer, and the waterfall to Mývatn is another substantial leg. Rental cars, activities and accommodation change with the date, so compare the current total before booking.

On a day with whale watching booked, the biggest loss is not skipping a free attraction; it is breaking the connection between the whole activity and accommodation plan. Sea trips depend on wind and waves, while an outdoor side route may already be unsuitable in the morning. Putting both on one day stacks two uncertain factors together. I would give whale watching a full half-day in Húsavík and place the canyon and waterfall on another day with driving buffer, unless you are deliberately making the North-East crossing.
