The answer to what is the Diamond Circle is not simply “a scenic drive.” It is a route through some of North Iceland’s biggest geological contrasts: a broad waterfall fed by a glacial river, steaming volcanic ground, Europe’s most powerful waterfall, a horseshoe-shaped canyon, and a harbor town with a strong connection to the sea. The route is often done in one long day, but it is better understood as a collection of places that deserve time, good weather judgment, and a little flexibility.
For travelers based in Akureyri, Laugar, or the Lake Mývatn area, the Diamond Circle can be a memorable day out. It can also be surprisingly demanding if you try to see every stop at top speed. Distances are manageable, but weather, road conditions, walking time, and daylight all shape what makes sense.
What is the Diamond Circle?
The Diamond Circle is a roughly 155-mile sightseeing route in North and Northeast Iceland. Its best-known stops are Goðafoss waterfall, the Lake Mývatn area, Dettifoss waterfall, Ásbyrgi Canyon, and Húsavík. The route is commonly traveled as a loop, using a mix of Route 1 and regional roads.
Its name is well chosen. Each stop has a very different character, but together they show how fire, ice, water, and the North Atlantic have shaped this part of Iceland. You may stand in quiet birch woodland at Ásbyrgi in the morning and hear the enormous force of Dettifoss a few hours later. Near Mývatn, the landscape shifts again to lava fields, pseudocraters, geothermal vents, and volcanic ridges.
There is no single required direction, and there is no rule saying you must visit all the major sites in one day. A private route can be adjusted around your interests, the season, and the roads that are actually open.
The main Diamond Circle stops
Goðafoss
Goðafoss is a wide, graceful waterfall on the Skjálfandafljót River, just off Route 1. It is one of the easier major waterfalls to reach and works well as an early stop when traveling from Akureyri toward Lake Mývatn or as a final stop on the way back.
The waterfall is tied to a famous story from Iceland’s conversion to Christianity around the year 1000. According to tradition, lawspeaker Þorgeir Ljósvetningagoði threw statues of the old Norse gods into the falls after Iceland adopted Christianity. Whether you come for the history, the photographs, or simply the sound of the river, it is worth walking to more than one viewpoint.
Lake Mývatn and the volcanic landscape
Lake Mývatn is not one attraction but an entire area of geological features. It is where the Diamond Circle becomes less about checking off landmarks and more about reading the landscape.
Depending on time and conditions, a day in the area may include the pseudocraters at Skútustaðagígar, the strange lava formations at Dimmuborgir, the colorful slopes around Námafjall, or a walk through the Krafla volcanic area. Steam vents, sulfurous ground, fresh-looking lava, and quiet wetlands can all be found within a short drive of one another.
This is also a place where local knowledge makes a real difference. Some walks are short and straightforward; others are more exposed to wind or can be muddy after rain. In winter, snow and ice change both access and the experience. The right stop depends on whether you are traveling with children, hoping to photograph geothermal details, or looking for a longer walk with fewer people around.
Dettifoss
Dettifoss is the dramatic centerpiece for many visitors. Fed by glacial water from Vatnajökull, it is famous for its volume and raw power. The river is gray-brown with sediment, the canyon walls are dark, and the spray can be felt well before you reach the main viewpoint.
There are approaches from both sides of the river, and they are not interchangeable. The west side is generally the more accessible choice, with a paved approach road for much of the season. The east side has a rougher gravel road and can offer a different angle, but it is more dependent on conditions and usually requires more time. The best choice is not always the same one shown in a photograph.
Allow time to walk from the parking area and to visit nearby Selfoss if conditions permit. Selfoss is lower and wider than Dettifoss, with water spreading across a broad series of drops. It is an excellent reminder that the canyon is a landscape in its own right, not just a place to take one waterfall picture.
Ásbyrgi Canyon
Ásbyrgi is a huge, horseshoe-shaped canyon in Vatnajökull National Park. Its sheltered floor, woodland, cliffs, and calm pond create a striking contrast with the open highland feel around Dettifoss.
Icelandic folklore says Ásbyrgi was made by one of the eight-legged horse Sleipnir’s hooves. Geology tells a different but equally impressive story: the canyon was formed by enormous glacial floods thousands of years ago. Both stories fit the place. Ásbyrgi feels unusually protected and almost theatrical, especially when low cloud hangs over the cliffs.
For some guests, a short walk near the pond is enough. Others prefer a longer trail or a quieter pause among the trees. It is also a useful stop on a windy day, since parts of the canyon are more sheltered than the exposed coast and waterfall areas.
Húsavík
Húsavík adds a human and maritime side to the route. The town sits on Skjálfandi Bay and is known for its harbor, whale-watching tradition, and compact old-town character. Even if you are not taking a boat tour, it is a pleasant place to stretch your legs, have a meal, and look out over the water.
The weather here can be quite different from conditions inland. A clear day at Lake Mývatn does not guarantee calm water or clear skies on the coast. That is one reason a flexible itinerary is more useful than a rigid checklist.
Can you drive the Diamond Circle in one day?
Yes, but it depends on where you start, the season, and how much walking you want to do. From Akureyri, a full loop with the principal stops can easily become a long day. From Lake Mývatn or Laugar, the driving can be shorter, but there is still more to see than most people expect.
In summer, long daylight hours make a full-day route realistic. That does not mean every road will suit every driver. Gravel sections can be dusty, washboarded, or slippery after rain, and sheep may be on or near the road. In winter, road closures, wind, drifting snow, and limited daylight can make a complete loop impractical. At that time of year, it is often wiser to focus on the best accessible parts rather than chase every named stop.
A self-drive day gives you independence, but it also asks someone in the group to watch the road, assess changing conditions, and keep track of time. A guided private day offers a different kind of value: you can look out the window, take your time at the places that interest you, and adjust the plan when weather changes. For travelers who want context as well as scenery, a local guide can connect the waterfalls and lava fields to the stories of the farms, eruptions, and people who live nearby.
How to plan a better Diamond Circle day
Start by choosing your priority. If Dettifoss is non-negotiable, build the day around road access and walking time there. If you are most interested in geology, give Lake Mývatn more room. If you prefer gentler walks and a quieter atmosphere, Ásbyrgi may deserve more than a quick stop.
Dress for more than one kind of weather. Waterfall spray, wind, and uneven ground are common even on a sunny forecast. Waterproof outer layers, sturdy shoes, and a warm layer are sensible year-round. A camera cloth is useful at Dettifoss, where spray can quickly cover a lens.
It also helps to accept that the best route is not always the longest route. A day with two unhurried walks, changing light over Lake Mývatn, and a safe return can be far more rewarding than a rushed loop completed only because a map said it was possible.
The Diamond Circle is at its best when you leave room for the unexpected: a patch of light on the canyon walls, birds on Lake Mývatn, a roadside story, or the decision to stay a few more minutes because the view is simply too good to hurry away from.
