Top 10 Waterfalls in Iceland
Iceland sits on a volcanic plateau soaked by North Atlantic storms and capped by glaciers, a combination that produces waterfalls in extraordinary density. Rivers spill off basalt edges every few kilometres along the Ring Road, fed by rain, snowmelt, and meltwater from icecaps like Vatnajökull. Many are roadside; a few demand a hike. The selection below ranges from the country's most photographed curtains to its most powerful single drop. All ten sit on the map.
1. Gullfoss, Suðurland
Gullfoss, the Golden Falls on the Hvítá river, is the centrepiece of the Golden Circle. It drops in two stepped stages totalling 32 metres, the lower step plunging into a narrow crevice set at right angles so the water appears to vanish into the earth. Fed by glacial meltwater from Langjökull, it runs year round and is busiest in summer. Two viewpoints, the upper by the car park and a lower path, give very different perspectives.
2. Dettifoss, Norðurland eystra
Dettifoss on the Jökulsá á Fjöllum is the most powerful waterfall in Europe by average flow, discharging up to 500 cubic metres per second in summer. It is 100 metres wide and 44 metres tall, grey with glacial sediment from Vatnajökull. The west bank (road 862) is paved and easier; the east bank (road 864) is rougher but closer to the lip. Peak flow July to August.
3. Seljalandsfoss, Suðurland
Seljalandsfoss drops 60 metres off a former sea cliff in the south, and a path runs behind the falling curtain into a mossy alcove — one of the few walk-behind falls in Iceland. Fed by meltwater from Eyjafjallajökull, it flows year round, though the behind-path can ice over and close in winter. A short walk north reveals the hidden Gljúfrabúi tucked in a slot canyon.
4. Skógafoss, Suðurland
Skógafoss drops a clean 60 metres over a 25-metre-wide cliff on the Skógá river, also a relict sea cliff. Its sheer volume throws constant spray that produces frequent rainbows on sunny afternoons. A staircase of 527 steps climbs to a viewpoint above, where the Fimmvörðuháls trail continues past some two dozen further cascades. Year-round flow.
5. Goðafoss, Norðurland eystra
Goðafoss, the Falls of the Gods on the Skjálfandafljót, sweeps 12 metres over a horseshoe-shaped basalt rim some 30 metres wide. Its name recalls the year 1000, when the lawspeaker Þorgeir is said to have thrown his pagan idols into the falls upon Iceland's conversion to Christianity. Roadside off Route 1, year-round flow.
6. Svartifoss, Suðurland
Svartifoss in Skaftafell, part of Vatnajökull National Park, drops 20 metres framed by hexagonal black basalt columns that inspired Icelandic architects. A 1.5-kilometre uphill trail from the visitor centre reaches it. The columns break off as the falls erode their base, leaving the jagged organ-pipe edge. Flow is steady, fed by highland meltwater.
7. Háifoss, Suðurland
Háifoss, near the Þjórsá valley, is one of Iceland's tallest falls at 122 metres, dropping into a deep canyon alongside its neighbour Granni. A rough gravel track (4x4 advised) and a short walk reach the rim. Fed by the Fossá river, it flows year round but is best reached in summer when the track is dry. The canyon walls reveal stacked lava layers.
8. Dynjandi, Vestfirðir
Dynjandi, the jewel of the Westfjords, fans out as it falls 100 metres, widening from 30 metres at the top to 60 at the base in a trapezoid of white threads. A series of smaller falls steps below it to the fjord. The name means thunderous. Access is by a short uphill walk; the remote Westfjords location keeps crowds thin. Best June to September.
9. Hraunfossar, Vesturland
Hraunfossar is unlike any other on this list: instead of a river plunging, clear groundwater seeps out of the edge of the Hallmundarhraun lava field along a kilometre of bank, spilling into the Hvítá in countless small rivulets. There is no single drop, but the breadth is mesmerising. Year-round, and especially blue against autumn birch.
10. Aldeyjarfoss, Norðurland eystra
Aldeyjarfoss on the Skjálfandafljót drops 20 metres into a pool ringed by dramatic basalt columns, the dark rock contrasting with the white glacial water. It sits at the northern edge of the highlands; the final stretch of road is rough and best in summer. Less visited than Goðafoss downstream, it rewards the detour.
Planning an Iceland waterfall trip
The Ring Road (Route 1) passes within reach of most falls on this list, and a full circuit in summer can take in Seljalandsfoss, Skógafoss, Svartifoss, Goðafoss, and Dettifoss in sequence. The South Coast cluster (Seljalandsfoss and Skógafoss) is an easy day from Reykjavík. The Westfjords (Dynjandi) and the highlands (Háifoss, Aldeyjarfoss) require detours on rougher roads, generally passable June to September. Glacial-fed falls run strongest in July and August when meltwater peaks.
Why Iceland has so many falls
Three factors combine. First, heavy precipitation — the south coast receives over 3,000 millimetres of rain a year. Second, recent volcanic geology: young basalt forms hard, sharp edges that rivers drop over cleanly rather than wearing into gentle slopes. Third, glaciers, whose summer melt feeds rivers that never run dry. The relict sea cliffs of the south, stranded inland as the land rose after the Ice Age, give falls like Seljalandsfoss and Skógafoss their characteristic clean vertical drop.
