Hvannadalshnúkur is a pyramidal peak located on the northwestern rim of the summit crater of the Öræfajökull volcano in Iceland. Situated within the administrative area of Sveitarfélagið Hornafjörður and part of the Vatnajökull National Park, it rises as a nunatak above the surface of the Vatnajökull glacier.
Standing at an elevation of 2,110 m with a prominence of 2,110 m, Hvannadalshnúkur is the highest point of the country and the highest of 502 named peaks in the Highlands of Iceland. It serves as a prominent landmark on the southeastern periphery of the island.

Geographically, Hvannadalshnúkur belongs to the range hierarchy of the North Atlantic Ocean > Iceland > Highlands of Iceland. It is located in the southern part of the country within the administrative area of Sveitarfélagið Hornafjörður in Austurland. As the highest mountain in Iceland, it ranks as the highest among 502 named peaks in the Highlands of Iceland. The surrounding landscape features vast glacial expanses, ice-capped volcanic calderas, and deeply eroded terrain where nunataks pierce the ice sheet.
Hvannadalshnúkur is surrounded by several close peaks and mountain passes within the glacial terrain:
Surpassing all of these immediate neighbours, Hvannadalshnúkur stands as the supreme elevation in the immediate vicinity.
From the high point of Hvannadalshnúkur, wide views open up across the ice fields and surrounding terrain. The highest peaks within a 25 km radius include Hrútsfjall at 1,721 m located 5.9 km NW, Knappar at 1,457 m situated 5.4 km SE, Þuríðartindur at 1,741 m found 7.8 km N, Skarðatindur at 1,385 m lying 12.2 km NW, Mavabyggdir at 1,439 m positioned 16.0 km N, and Miðfellstindur at 1,430 m located 18.0 km NW. On clear days, these surrounding giants and the vast expanse of the Vatnajökull glacier are visible from the summit.
The mountain range encompassing the peak spans from the North Atlantic Ocean across Iceland to the Highlands of Iceland. Within this mountain range, which contains 502 named peaks, Hvannadalshnúkur holds the rank of the highest peak. The high point of the range is located in an unnamed area of the Central Highlands.
Climate estimates based on NASA POWER 2001–2020 monthly means, adjusted to the summit elevation, indicate that the warmest month at the summit is July with a mean temperature of about -3 °C, while the coldest is February at about -7 °C. There are no months with a mean temperature above freezing at the summit. In the surrounding area, precipitation is about 2,400 mm a year, with January being the wettest month at about 280 mm and June the driest at about 95 mm. Mountain weather in this region is notoriously volatile, featuring sudden blizzards, high winds, and severe whiteout conditions due to the proximity of large ice caps.
Given that the summit experiences sub-freezing mean temperatures year-round with no months averaging above freezing, and that the surrounding area receives heavy annual precipitation peaking in the winter months, the window for climbing is traditionally restricted to the warmer months. Late spring and summer offer more stable weather patterns, longer daylight hours, and slightly more favourable conditions for navigating the heavily crevassed glacial routes.
The natural environment around Hvannadalshnúkur is dominated by high-altitude glacial ice, snowfields, and exposed liparite rock formations of the eroded Öræfajökull volcano. Vegetation is virtually absent at the summit elevation due to extreme cold and ice cover, though hardy mosses and lichens can be found in lower coastal and valley areas. Wildlife is similarly sparse high on the glacier, limited occasionally by migrating birds passing overhead, while arctic foxes and reindeer inhabit lower tundra and coastal regions of Iceland. The area is protected within the bounds of the Vatnajökull National Park.
Because the route to the summit traverses numerous treacherous glacial crevasses and requires technical glacier travel skills, engaging a certified mountain guide is strongly recommended for inexperienced climbers. The national mountain guide association in the country is the Association of Icelandic Mountain Guides (Félag fjallaleiðsögumanna á Íslandi (AIMG)), which is not an IFMGA/UIAGM member. The national alpine club is the Icelandic Alpine Club (Íslenski Alpaklúbburinn, ÍSALP). Established guiding companies operating in the country include Icelandic Mountain Guides based in Reykjavík and Arctic Adventures also based in Reykjavík. Guided ascents typically include safety equipment such as ropes, harnesses, and crampons, with prices varying based on group size and trip duration.
Ascending a high glacial peak demands proper mountaineering experience, physical fitness, and appropriate safety gear, including helmets, ropes, ice axes, and crampons. Hidden crevasses present a constant hazard on the ice-covered slopes. In the event of an emergency in the mountains of Iceland, the single emergency number for police, ambulance, and search and rescue is 112.
The first recorded attempt to climb the peak was made by Sveinn Pálsson, who reached a summit named Sveinsgrípa at 1,900 m. The Norwegian Hans Frisak likely made the first ascent in 1813, though he described it under the name Hnappur, which was widely believed throughout the 19th century to be the country's highest point. In 1891, Frederick W.W. Howell ascended Hnappur and recognized that Hvannadalshnúkur was higher, subsequently completing the first official ascent of the peak on the same day alongside Páll Jónsson and Þorlákur Þorláksson.
Over the decades, height measurements have varied due to scientific surveys and volcanic activity. Danish expeditions in 1904 calculated a height of 2,119 m using triangulation, and a 1955 survey measured 2,323 m. Later GPS measurements in 1993 by the University of Iceland Institute of Natural Sciences placed it at 2,111 m, a figure reaffirmed by the Icelandic Glaciological Society in 2004. In July 2005, the National Land Survey of Iceland established the final official height of 2,109.6 m, which was publicly announced by then Prime Minister Halldór Ásgrímsson.
Etymologically, the name translates as the Peak of Angelica Valley, derived from hvanna (angelica), dals (valley), and hnjúkur (peak), referencing the nearby valley of Hvannadalur. In the Icelandic language, both Hvannadalshnúkur and Hvannadalshnjúkur are used equally, with spelling variations reflecting regional dialects across the country.
Hvannadalshnúkur is the highest point of Iceland and sits on the northwestern rim of the summit crater of the Öræfajökull volcano. It boasts a prominence of 2,110 m, matching its total elevation. Its profile makes it a visible navigational landmark for incoming aircraft flying toward the international airport in Keflavík.
