About This Route
The Aurlandsdalen Valley Trek is a premier backpacking adventure in the Sognefjord region of the Norwegian Fjords, stretching 47 kilometers from Østerbø to Vassbygdi over 4 to 6 days. This classic route follows the ancient Aurlandsdalen river valley, passing dramatic gorges, waterfalls like Vetledfossen, and lush meadows before ascending to barren plateaus near the Østerbø cabins. Managed by the Norwegian Trekking Association (DNT), it features staffed and unstaffed huts for overnight stays, making it ideal for multi-day backpacking. Expect elevation gains up to 1,000 meters, with daily stages of 8 to 15 km. The trail showcases the fjord's glacial history and offers stunning views of Aurlandsvangen far below. Suitable for those with prior backpacking experience, it embodies Norway's allemannsretten (right to roam) principles from Leave No Trace.
Safety Considerations
Follow the Norwegian Mountain Safety Code: plan your trip and inform others via the DNT app or a trusted contact; adapt to abilities and check Yr.no for weather and Varsom.no for avalanche risks, even in summer. Rapid weather shifts from sun to storms are common in the fjords; hypothermia risks rise with wet conditions. River crossings at Sinjarheim can swell after rain, so scout stable points. Ticks peak June-August; check skin daily and use tweezers. Steep descents near Ringstøl demand trekking poles for stability. Stay on marked red-T trails and cairns; off-trail navigation risks bogs or cliffs. Conserve energy, turn back if fatigued, and recognize fatigue signs early.
Essential Gear
Pack layers for variable fjord weather: waterproof jacket like Gore-Tex from Arc'teryx, fleece midlayer, and wool base from Icebreaker. Ankle-supporting boots such as Salomon Quest 4D GTX for rocky terrain. Map, compass (Sunnto), and GPS like Garmin inReach for no-signal areas. First-aid kit with blister care, tick remover, and painkillers. Headlamp with extra batteries, emergency bivvy, and multi-tool. Water filter like Sawyer Squeeze for streams; bear canister unnecessary but food bags for rodents. DNT key for hut access.
