A lake district formed by the eruption of 1477

Veiðivötn extends for roughly 20 kilometres from southwest to northeast and is about five kilometres across at its widest. The exact number of lakes depends partly on what is counted, but the district is commonly described as containing around fifty. Its northeastern group is known as Hraunvötn, the “lava lakes.”

The organising event was the eruption of 1477. A fissure system approximately 60–65 kilometres long became active in an eruption now estimated at volcanic explosivity index 5–6. Much of the Veiðivötn activity was explosive and basaltic. Magma met groundwater, fragmenting into immense quantities of tephra and building the crater rows that still structure the landscape.

The fissures extended southwest into the Torfajökull volcanic system and triggered separate silicic activity there. Laugahraun at Landmannalaugar belongs to that connected 1477 episode, but it is a Torfajökull lava flow rather than part of the basaltic crater-and-lake landscape of Veiðivötn. Keeping that distinction matters: one regional volcanic episode involved two different volcanic systems and more than one type of eruption.

Ljótipollur and Hnausapollur were also formed during the wider 1477 fissure event. They lie closer to Landmannalaugar and should not be presented as two of the Veiðivötn lakes. Their shared age connects the destinations geologically, not geographically.

Water within porous lava and tephra

The strongest visual contradiction at Veiðivötn is between water and apparently barren ground. Black and brown tephra, scoria and lava dominate the wider view, yet clear lakes occupy crater floors and depressions throughout the district.

Much of the volcanic ground is highly permeable. Rain and meltwater can disappear into it instead of gathering immediately into visible streams, and groundwater moves through the porous material. Many lakes are therefore influenced by subsurface inflow and drainage. Water levels and connections are not explained by surface channels alone.

This hidden movement of water also helps create the district’s ecological pattern. Vegetation is sparse across exposed volcanic surfaces, but mosses, grasses and wetland plants gather where moisture, shelter and finer sediment coincide. Around places such as Breiðaver and Ampapoll, greener wetlands interrupt the desert and provide nesting and feeding habitat.

Veiðivötn should not be understood as a dead landscape slowly being decorated by isolated patches of green. Water, volcanic material, plants, fish and birds form a functioning highland environment. Its life is concentrated rather than absent.

An isolated ice-age trout population

The brown trout of Veiðivötn is exceptional even before its size is considered. Genetic research indicates that the population became isolated above impassable waterfalls soon after the end of the Ice Age. It is regarded as an unusually pure surviving ice-age trout stock. Trout in Þingvallavatn belong to the same broad type.

These trout grow rapidly and mature later than sea-going trout or many populations in lowland lakes. Veiðivötn has consequently become known for unusually large and heavy fish. Individual catches vary greatly between lakes, seasons and years, but trout weighing several kilograms are a real part of the fishery; recorded fish have exceeded eight kilograms.

Arctic char are also found in the district and now contribute substantially to catches in some lakes. The two species should not be collapsed into one general description of “trout fishing.” Their distribution and abundance differ between waters.

The fish are not merely a recreational resource added to a dramatic setting. Their isolation connects the present lakes to the end of the Ice Age, while their productivity shows how much biological activity can be concentrated within cold highland waters.

Fishing, permits and accommodation

Fishing requires a permit. Permits may be arranged in advance and can also be available after arrival, but availability should be checked before a journey made principally for angling. Regulations, permitted lakes and the fishing period can change, so anglers must obtain the current rules rather than rely on an older account.

Non-anglers do not need a fishing permit simply to visit Veiðivötn. The crater landscape, lakes, wildlife and photographic possibilities make the district worthwhile without a rod.

Huts and camping facilities are concentrated around Tjaldvatn, where the destination coordinate on this page is placed. Accommodation can be booked, but services are modest and seasonal. Visitors should establish in advance what is open, what must be reserved and what food, water and equipment they need to bring.

There is no fuel or general supply service within the lake district. Veiðivötn is a place to arrive prepared, not somewhere to discover after arrival what the vehicle or group is missing.

Birds and mammals among the crater lakes

The first impression of Veiðivötn can be one of emptiness. Recorded wildlife tells a different story. Local observation lists contain 57 bird species: 22 regular breeding species, 11 species seen regularly without confirmed breeding, and 24 vagrants or occasional visitors.

The great northern diver, known in Icelandic as himbrimi, is the characteristic bird of Veiðivötn. Its calls and low profile on the water belong naturally to the quiet lakes. Ducks, geese, swans, shorebirds and snow buntings use different habitats across the district, while the wetlands around Breiðaver and Ampapoll are particularly important for nesting.

Three wild mammals are recorded: Arctic fox, American mink and wood mouse. Foxes and mice are encountered relatively infrequently, while mink is the mammal most often seen. Their presence does not mean wildlife sightings are guaranteed. The scale of the terrain, sparse cover and sensitivity of breeding areas reward patience and distance.

Birdwatchers and photographers must avoid approaching nests or pushing birds repeatedly from the shore. A long lens and a quiet position reveal more of the animal’s relationship with the lake than a close pursuit ever will.

Reaching Veiðivötn by F228

The usual approach begins near Hrauneyjar and follows the surfaced road towards Vatnsfellsvirkjun before continuing on F228. Beyond the power-development roads, the journey enters rougher highland terrain and requires a proper 4×4.

F228 includes two principal river crossings on the approach. They may be maintained during the summer travel period, but a prepared ford can deepen or change again. Rain, meltwater and movement within the riverbed can turn a manageable crossing into a difficult one. Maintenance is not a guarantee of safe passage.

Before entering any ford, assess the current, depth, riverbed and exit. Never assume that another vehicle’s tracks prove the crossing is suitable for yours. If the water cannot be judged confidently, turn back.

Road access is seasonal, but fixed opening and closing dates are misleading. Check the official road-condition information and the weather before departure. Conditions within Veiðivötn may also differ from those on the approach.

F229, drifting sand and highland self-reliance

F229 provides an alternative approach that avoids the two principal river crossings on F228. It is useful when water conditions make the usual route unsuitable, but it replaces one difficulty with another. Loose and drifting sand can make F229 challenging and can trap a vehicle that lacks clearance, traction or an experienced driver.

Neither route should be presented as the easy choice. The appropriate approach depends on current water, sand, weather and road conditions. A proper 4×4 improves capability but does not make every crossing or sand section safe.

Roads within the lake district include rough sections and further fords. Stay on established roads and tracks. Driving across undisturbed tephra or vegetation is both illegal off-road driving and a source of damage that can remain visible for decades.

Mobile coverage cannot be relied upon. Carry suitable clothing, food, water and basic emergency equipment, and be prepared to change a tyre or wait safely after a breakdown. Tell someone the route and expected return. In a remote district, a small mechanical problem can become the main event of the day.

Visiting without fishing

Veiðivötn rewards slow observation. The landscape is too extensive to be understood from a single lake or brief stop. Crater rows, water levels, wetlands and the changes between bare and vegetated ground become clearer as the route moves through the district.

Visitors should not treat every shoreline as freely accessible by vehicle. Park only where the ground and route allow, respect angling activity and accommodation areas, and keep away from nesting birds. Leave no waste and avoid creating new foot or tyre tracks.

The visitor facilities at Tjaldvatn provide a practical centre, but they are not the whole destination. Veiðivötn is the wider relationship between the 1477 fissures, the lakes held within their craters, the groundwater beneath them and the life concentrated around their shores.
