Kerlingarfjöll Hiking Tour in Iceland's Highlands
A kerlingarfjöll hiking tour leads you through the Hveradalir geothermal valley, where rhyolite ridges in ochre and rose sit beside steaming fumaroles and hot springs fed by the mountains' snowfields. Guided kerlingarfjöll hiking tour tours follow marked trails past boiling mud pools and glacial streams, with the Kjölur highland route and Hofsjökull glacier framing the horizon. Most Kerlingarfjöll walking tours run from the Highland Base area, and Kerlingarfjöll hiking tour tickets typically include the F-road transfer that ordinary rental cars cannot legally make.
A summer ski school ran on the snowfields above Ásgarður for nearly four decades, closing in 2000 once the seasonal snow thinned past use. The mountains that carried its lifts are not ordinary basalt.
Rhyolite — pale, iron-stained, chemically closer to granite than to lava — streaks the ridges ochre, rust and sulphur yellow, which is why a Kerlingarfjöll hiking tour looks unlike anything on the coastal ring road.
The range stands between two ice caps, Langjökull to the west and Hofsjökull to the east, astride the Kjölur route that medieval travellers used to cross the interior on horseback. Its name translates as the old woman's mountains, after a rock pillar read for centuries as a petrified troll. Farmers gave the interior a wide berth; outlaws did not. Access arrived late. The F347 track that climbs to the valley floor was improved for the ski school, and it remains the only road in, which is why the Kerlingarfjöll hiking trails still trace herders' and skiers' lines rather than engineered switchbacks, and why a Kerlingarfjöll hiking tour from Reykjavík has always begun with a long drive inland.
Below the ridges lies Hveradalir, among the largest geothermal fields in Iceland: fumaroles venting at boiling point, mud pools, and streams that run warm where they mix with meltwater. Snækollur, the high point at roughly 1,477 metres, holds snow deep into the summer. Loðmundur and Fannborg close the basin to the north. Iceland granted the area formal protection in 2020, and the reason for the boardwalks is written into the ground itself — the surface crust over a fumarole can be a few centimetres thick. Kerlingarfjöll hiking tour tours keep to marked ground for exactly that reason, and a Kerlingarfjöll hiking day tour from Reykjavík covers close to 190 kilometres in each direction to reach the trailhead.
That distance explains the range's late arrival in the public imagination. For most of the twentieth century this was a destination for skiers, geologists and members of the Icelandic touring associations rather than for visitors. Ásgarður now operates as a year-round highland base, and the valley draws walkers who once would have driven past the turnoff toward Gullfoss. What a Kerlingarfjöll hiking tour tour offers is not summit conquest but a compressed lesson in Icelandic geology: two glaciers, one volcanic system, and a coloured landscape still being assembled by heat.
