Sognefjellsvegen is the name associated with Norway’s National Cycle Route 6, a long-distance journey between the Røros and Bergen areas. Its mountain crossing over Sognefjellet is also part of a Norwegian Scenic Route, taking riders from the cultivated valley around Lom towards Sognefjorden. The Norwegian Public Roads Administration includes the route in its national cycling network.
A route across Norway
The Norwegian Public Roads Administration lists Sognefjellsveien as National Cycle Route 6 and highlights the World Heritage places of Røros and Bergen alongside the scenic roads at Rondane and Sognefjellet. Cycle Norway describes the overall journey as running from Røros via Sognefjellet to Bergen.
The Sognefjellet crossing is one part of that broader itinerary. Norwegian Scenic Routes describes its own Sognefjellet road between Lom and Gaupne and confirms that it coincides with National Cycle Route 6. Its stated 108 km length applies to the scenic-road section, not to the whole national cycle route.
From Lom over Sognefjellet
Lom is the scenic-route operator’s recommended starting point for cyclists tackling Sognefjellet. The road rises through Bøverdalen, leaving its meadows and cultivated landscape for high mountain scenery. The summit reaches 1,434 metres above sea level, before the road descends towards the inner Sognefjord.
This is a demanding crossing: the operator warns of challenging climbs and a steep descent to Fortun. Along Lustrafjorden, the scenic-route description says the cycle route is signposted. Do not assume the same level of signage throughout the longer journey.
Places to pause
Lom’s stave church offers a cultural stop near the mountain crossing. Higher up, Norwegian Scenic Routes lists places to pause including Sognefjellshytta, Mefjellet and Oscarshaug. The changing landscape continues towards Gaupne, where the road follows Sognefjorden.
For riders adding time off the bike, the operator identifies the old waymarked Cairn Track between Krossbu and Turtagrø and the Mefjell Track, which begins at the stone sculpture. Treat these as walking options and plan them separately from the cycling itinerary.
Planning the crossing and onward journey
The mountain road between Rustasætre or Vegaskjelet and Turtagrø closes in winter. Even after reopening, it may close at night or during bad weather. Check the road authority’s current traffic information before committing to the crossing.
Tunnel access also matters on the longer route. Cycle Norway warns that several tunnels are closed to cyclists and identifies a train transfer through the Vossevangen–Trengereid section. Check current restrictions, connections and bicycle carriage arrangements in advance. The road authority notes that its national routes commonly use roads with mixed traffic and recommends effective front and rear lights.
