Traversing 104 kilometres through Møre og Romsdal, County Road Fv63 links the alpine precipice of Trollstigen with the UNESCO World Heritage waters of the Geirangerfjord. Defined by dramatic elevation changes, hair-pin engineering, and modernist viewing structures, it is Norway's premier mountain pass road trip.
Topography & The 11 Hairpin Bends of Trollstigen
Opened by King Haakon VII in 1936 after eight years of manual rock excavation, Trollstigen ("The Troll's Ladder") climbs 858 metres from the valley floor of Isterdalen to the Stigrøra plateau. The road ascends at an average gradient of approximately 9 percent through 11 acute switchbacks carved into vertical cliff faces.
Midway through the ascent, vehicles cross the historic natural stone arch bridge over the thundering Stigfossen waterfall, which drops 320 metres down the mountainside. Water spray frequently coats vehicles crossing the span, requiring working wipers and functional traction control.
Landmark Architectural Works
Nowhere is the dialogue between Norwegian nature and modern architecture more pronounced than along Fv63:
- Trollstigen Visitor Centre (Reiulf Ramstad Arkitekter): Constructed with cast-in-place concrete and untreated Corten steel, this building houses water cascades diverted through architectural channels. Cantilevered pathways project out into mid-air over the Isterdalen valley.
- Gudbrandsjuvet (JVA - Jarmund/Vigsnæs): Located in Valldal, an intricate elevated steel walkway network allows visitors to peer directly down into a narrow, churning 5-metre wide, 20-metre deep gorge carved by the Valldøla river.
- Ørnesvingen (The Eagle Bend): The highest of eleven hairpin turns ascending from Geiranger toward Eidsdal. The viewing platform features a glass floor panel and an integrated artificial waterfall fed by local stream run-off, overlooking the "Seven Sisters" waterfalls (De syv søstre).
- Flydalsjuvet: A classic panoramic stop south of Geiranger, providing the quintessential high-altitude view of cruise ships resting on the green waters of the inner fjord basin.

Driving Considerations: Campervans, Grades & Rockfall Management
Route Highlights
- World-famous switchback engineering unmatched in Northern Europe.
- Seamless blend of UNESCO marine fjord scenery and glaciated peaks.
- World-class visitor facilities with museum-grade architectural viewpoints.
- Direct access to Dalsnibba (Geiranger Skywalk at 1,500m).
Challenging Factors
- Strict seasonal window; road remains closed for nearly seven months of the year.
- High brake rotor temperatures on descents; manual low gearing is essential.
- Occasional rockfall closures (Statens vegvesen monitors slope sensors closely).
- Dense tour coach traffic during July peak hours causing delays at switchback corners.
Transmission & Braking Guidance
When descending Trollstigen toward Åndalsnes, drivers operating automatic gearboxes should switch into manual mode ("M" or "L") and select 1st or 2nd gear. Relying exclusively on wheel brakes will rapidly induce brake fluid boiling and brake fade. If you smell heated brake pads, immediately use a designated pull-out bay to let rotors cool.
Vehicles traveling uphill have the right of way under standard Norwegian road conventions when negotiating narrow passing spaces, but long commercial buses must be yielded to regardless of direction.
