About This Route
Trolltunga, the 'Troll's Tongue,' in Hardangerfjord is a bucket-list trail run spanning 28 kilometers round trip from P2 parking near Ringedalsvatnet lake in Odda. Gain 900 meters elevation through boulder-strewn plateaus, snow patches, and chain scrambles to a cantilevered rock jutting 700 meters above Ringedalsvatnet. DNT-marked with red 'T's and cairns, it's a full-day effort (4-7 hours for strong runners). The remote Hardanger region's glacial scenery rewards, but isolation amplifies risks. Respect allemannsretten by minimizing impact on fragile alpine tundra.
Safety Considerations
Follow the nine-point Norwegian Mountain Code religiously: inform contacts of your start time and ETA via safetips.no. Monitor Yr.no and Varsom.no for storms or snowmelt floods. Depart before 6 AM to beat crowds and heat; afternoon thunderstorms are common. Acclimate to altitude; hypoxia hits fast above 1,000m. Navigate with Norgeskart app, compass, and paper map, as signals fade beyond Skjeggedal. Conserve energy on technical descents to prevent knee strain. Filter lake water with Sawyer Squeeze. Beware reindeer herds; yield right-of-way.
Essential Gear
Opt for durable trail shoes like Hoka Speedgoat 5 for rocky terrain; Gore-Tex rain shell from Patagonia Torrentshell; insulated mid-layer such as Rab Kinetic 2.0; 20L pack like Osprey Talon 22 with 2L water, energy bars, and spare socks; PLB or inReach Mini for SOS; DNT Hardanger map; multi-tool, duct tape, and Sam Splint; buff and polarized sunglasses. REI stresses redundancy in navigation tools.
