Physical Features of Hrafntinnusker Mountain Peak
Hrafntinnusker is a 3,743-foot (1,140-meter) mountain in Iceland’s remote Highlands and lies within the Fjallabak Nature Reserve, a protected area known for its geothermal and volcanic features.
Although classified as a mountain, its name ends with “sker” (skerry), reflecting a regional naming tradition in parts of Southeast Iceland, where terms for hills, peaks, and skerries are often used interchangeably regardless of size.
The peak is part of the Torfajokull Volcanic System (Torfajökull), one of Iceland’s most active geothermal zones. Its landscape is defined by layers of pale rhyolite, black obsidian, and vibrant mineral deposits, giving the area a highly varied surface texture and coloration.
Obsidian—formed when acidic lava cools rapidly—is found in scattered chunks across the mountain, and the name Hrafntinnusker directly refers to this volcanic glass.
Despite its modest size, Hrafntinnusker Mountain Peak supports a tiny, persistent snowfield or glacier remnant at its summit, shaped both by seasonal snowfall and the geothermal heat that escapes from the ground below.
The combination of elevation, geothermal activity, and lingering snowfields makes the terrain harsh, rocky, and unusually colorful, with steam and ice often seen side by side.
The surrounding area, particularly to the west, contains a wide active geothermal zone filled with fumaroles, clay-rich hot springs, and steaming vents, some of which lie beneath glacial remnants. These underground forces continue to shape the mountain’s evolving form and contribute to the raw, dramatic character of this isolated landscape.
Where Is Hrafntinnusker Mountain Peak Located
Hrafntinnusker Mountain Peak is located in the Icelandic Highlands, between Landmannalaugar and Alftavatn Lake, along the famous Laugavegur Trail. It sits at an elevation of 3,743 feet (1,140 meters) and lies within the Fjallabak Nature Reserve, an area known for its geothermal activity, colorful rhyolite mountains, and remote wilderness.
The peak is part of the Torfajokull Volcanic System, one of Iceland’s most active and geothermally rich regions.
While it may appear relatively central on the map, Hrafntinnusker Mountain Peak is extremely remote—there are no roads leading directly to it, and it is accessible only on foot, most commonly via the Laugavegur Trail.
The closest access point is Landmannalaugar, which serves as the trailhead for hikers heading south toward Thorsmork Glacial Valley (Þórsmörk).
Top Things To Do in Hrafntinnusker Mountain Peak
Hrafntinnusker Mountain Peak may be remote, but its raw landscape offers plenty to discover. Visitors can expect steaming vents, colorful rhyolite hills, obsidian fields, and lingering snow. It’s a natural playground for those hiking through Iceland’s wildest terrain.
Here’s what you can do once you reach the peak of Hrafntinnusker Mountain:
Walk Through Steaming Geothermal Landscapes
Explore the western side of Hrafntinnusker Mountain Peak, where steam constantly rises from the ground and the air smells faintly of sulfur. This active geothermal zone is filled with fumaroles, clay-rich hot springs, and steaming vents, some of which lie beneath patches of glacial ice.
Follow safe paths through the area and watch the colors shift under your feet—from bright yellows and oranges to silvery whites—created by minerals like sulfur, iron, and silica.
Friendly reminder: Just be cautious around active vents, as the ground can be unstable near them.
To learn more about this natural phenomenon, take a look at some of Iceland’s other geothermal areas.
Find Obsidian Rocks in Iceland’s Wild Highlands
Keep an eye out for obsidian, a shiny black volcanic glass that gives Hrafntinnusker Mountain Peak its name (hrafntinna means obsidian in Icelandic).
Formed from rapidly cooled lava, these glass-like fragments can be found throughout the area, but are easier to spot near the hut and along the eastern and southeastern slopes, where snow melts earlier and the terrain is more open. Obsidian is also present near geothermal zones, where heat and erosion expose ancient lava layers.
These dark shards scattered across the landscape add a striking visual contrast to the colorful rhyolite surroundings.
Spot Snow Caves Hidden in the Summer Snowfields
Even in midsummer, snow still lingers around Hrafntinnusker Mountain Peak’s high elevations. As you walk through the area, keep an eye out for shallow hollows or rising steam where the snow looks thin. In these spots, geothermal heat from below can melt the snow and create temporary snow caves, especially where ice and warm ground meet.
These hollow formations may appear near glacial remnants or geothermal features.
Friendly Reminder: As beautiful as they are, snow caves here are highly unstable. Melting from below can cause parts of the ceiling to collapse without warning. Always observe them from a safe distance.
Marvel at the Rhyolite Peaks and Lava Formations
Take time to explore the rhyolite ridges and lava formations surrounding Hrafntinnusker. Follow the trail up to higher viewpoints or walk short detours around the hut to see the colorful slopes up close.
The rhyolite here is rich in minerals, giving the peaks their soft reds, greens, yellows, and pinks, especially striking when framed by snow patches or drifting steam.
Look for jagged lava fields and warped rock formations shaped by ancient eruptions within the Torfajokull Volcanic System. These striking remnants reveal the volcanic power that helped form the surrounding highlands.

Watch the Midnight Sun Over the Mountains
If you're visiting in late June or early July, take time in the evening to experience the midnight sun as it appears in Iceland’s Highlands. While the sun briefly dips below the horizon at this latitude, the sky remains brightly lit through the night, casting a golden glow across Hrafntinnusker’s snowfields, obsidian patches, and rhyolite peaks.
The high elevation and total absence of light pollution make the moment feel even more surreal.
Tip: Even when the sky stays bright, temperatures can drop fast at this altitude. Layer up and keep an eye on the weather if you're staying out late.
Staying Overnight at Hrafntinnusker Mountain Peak
Perched at 1,100 meters above sea level on the eastern side of the mountain, the Hrafntinnusker Hut, officially known as Hoskuldsskali (Hoskuldsskáli), has served as a vital stop for Laugavegur Trail hikers since it was built in 1977.
Operated by the Icelandic Touring Association (Ferðafélag Íslands, FÍ), the hut offers basic accommodation for up to 52 people and is typically the first overnight stop for those hiking south from Landmannalaugar.
The main hut has bunk beds, a communal kitchen, cold running water, and dry toilets, but there are no showers or electricity. A warden’s cabin sits just west of the main building, and an additional latrine is located down by the camping area, which rests on gravel, sand, or snow, depending on the conditions.
Icelandic camping is allowed near the hut, but keep in mind that the high altitude and exposure mean nights can be extremely cold, even in mid-summer.
The site is only accessible on foot, and although a rough dirt road exists, it is almost never used except to deliver supplies. All guests are expected to pack out their trash and leave no trace.
Day visitors must pay a small facility fee to use the outdoor toilets, benches, and grill area. This fee goes directly toward maintaining and improving facilities across Iceland’s fragile highland areas.
The hut is open and staffed only during summer, typically from late June to mid-September, depending on trail and road conditions in the Fjallabak Nature Reserve.
Note: Reservations are essential for overnight stays, as space fills quickly during the hiking season.
