Reaching a maximum summit altitude of 1,434 metres above sea level, County Road Fv55 over Sognefjellet is Northern Europe's highest paved mountain pass. Traversing the borderlands of Jotunheimen National Park, this 108-kilometre route links Lom in the historic Gudbrandsdalen valley with Gaupne along the turquoise arms of the Sognefjord.
Geography & The Roof of Norway
The pass crosses an austere, permafrost tundra landscape surrounded by Norway’s loftiest peaks, including Galdhøpiggen (2,469 m) and the jagged Store Skagastølstind. The corridor was historically an essential trade artery for packhorses carrying salt and fish from the western fjords inland in exchange for butter, pitch, and hides.
During spring re-opening operations in early May, rotary snowblowers carve through snowdrifts often towering 5 to 10 metres high on either side of the roadway. Driving between these sheer walls of compacted blue glacial ice provides one of the continent's most surreal motoring experiences.
Architectural Viewpoints & Installations
Statens vegvesen commissioned landmark installations that pay homage to the high-alpine granite and slate geology:
- Mefjellet (Carl-Viggo Hølmebakk): An open-air stone amphitheatre situated in the harsh alpine zone. Its centerpiece is a massive cubic stone sculpture by artist Knut Wold, which functions as a geometric window framing the glaciated Fanaråken peaks.
- Vegaskjelet Viewpoint: Positioned on the eastern ascent from Bøverdalen, this cantilevered wooden terrace projects over the tree line to present an unencumbered sightline toward Skagsnebb and the Storbreen glacier.
- Liasanden Rest Area: Nestled within pine forests along the Bøvra river near Lom, featuring understated wooden tables and benches set organically around natural tree trunks without disturbing topsoil.
- Nedre Oscarshaug: Located on the western descent into Fortun, incorporating a directional brass disc that identifies surrounding peaks of the Hurrungane massif.

Pros & Cons: Driving the High Pass
Expedition Strengths
- Unsurpassed high alpine panorama without requiring technical mountaineering.
- Direct link between inland cultural hubs (Lom Stave Church) and the fjords.
- Excellent access to trailheads for classic summit hikes in Jotunheimen.
- Wide paved carriageway with fewer narrow pinch points than coastal routes.
Route Considerations
- Severe sudden weather shifts: thick fog (skodde) and blizzards can occur in summer.
- Long distances between charging stations and services across the plateau.
- Substantial battery drain on EV uphill ascents (though regained via regenerative braking on descent).
- No cellular reception in isolated dips of the high plateau.
Electric Vehicle Energy Management
When driving an EV from Gaupne up to Fantesteinen, vehicles consume battery reserves at more than double their flat-surface rate due to the continuous 1,400-metre altitude climb over 40 kilometres. However, descending from the plateau toward Lom regenerates significant kinetic energy, commonly recovering 10–18 percent of total battery capacity. Fast-charging stations are available in Lom and Sogndal.
