Rjukan in Norway is the ultimate winter outdoor adventure location, offering plentiful opportunities to explore and participate in the range of activities on its doorstep. Ali Rowsell suggests some things to do when you're sub-zero on the Telemark.

Only 2hr 30min from Oslo, this Scandinavian adventure capital is easily reached for a long weekend, with regular flights to Norway from the UK. Hiring a car from the airport offers the easiest access and, during the winter months, also guarantees a full winter package for driving on what appears to be the most daunting surface you could ever dread to travel on. The roads are surprisingly enjoyable for even the most cautious driver: the sub-zero temperatures provide a dry, snow-covered surface on which snow tyres grip sufficiently.

Rjukan caters for all adventurers: from the young to the old; the casual pace of a snowshoer to the speedy downhill skier; and from the history buff discovering the heroes of Telemark to the ice-climber hanging from their crampon and ice axe points on a frozen waterfall.

Rjukan is a world-famous ice climbing centre, with over 150 graded ice climbs within 5 minutes of the road.Rjukan has over 192 frozen waterfalls throughout its 6-month winter season, providing over 150 ice-climbing routes.Rjukan is situated in a large U-shaped valley sitting at 303m above sea level, with the towering summit of Gaustatoppen (1,883m) looming above.Rjukan offers perfectly groomed trails and is famous for hosting the FIS (Federation Internationale de Ski) competition in 2017.Being prepared and wrapping up warm is a must with temperatures dropping as low as -20 degrees.Perfect conditions for winter walking, snowshoeing, cross-country skiing and ski-touring.The area around Gaustatoppen (1,883m) is perfect for a range of winter activities.

Welcome to Rjukan

Rjukan is located in a deep U-shaped glacial valley, sitting at 303m above sea level within the Telemark area of Norway. The peak of Gaustatoppen, the highest mountain in southern Norway, stands above the southern side of the valley at a height of 1883m, blocking the winter sun. The founder of the town, Sam Eyde, thought out and suggested giant sun mirrors (Solspeil) in 1913, although they were not built until 2005 when Martin Anderson designed and completed the project. A 51m2 mirror now enables the market square to be lit up during the long, dark winter months.

Once a significant industrial centre, Rjukan has had a very wealthy past. Norsk Hydro started hydro-electric production in 1905 due to the high waterfalls throughout the valley. In 1934 the world’s largest hydro-electric powerplant was built at Vemork. It was made famous during World War II because of its advances in science and heavy water production (an important component required for the development of nuclear weapons). In 1943, a team of Norwegian Resistance fighters (the heroes of Telemark), who fled their Nazi-occupied country to train with British Commandos in the Cairngorm mountains of Scotland, were parachuted onto the Hardangarvidda plateau. Their mission, as part of Operation Gunnerside, was to sabotage the production of heavy water in an attempt to limit the Nazi war effort. Bombing raids had failed because of the topography and terrain of the valley, so a Special Operations Executive operation was needed. The team succeeded and escaped, skiing more than 200 miles south through Norway to freedom.

The site now hosts the Norwegian Industrial Worker’s Museum. It is open daily and offers an informative tour of Norway’s industrial prowess from the early 20th Century through to the present.

Rjukan is a fairly large town for Norway, with over 4000 inhabitants. Due to tourism and the local ski resort, Gaustablikk, just 15 minutes’ drive away, the town has many services, including four supermarkets, restaurants and cafés, alongside a selection of sports and tourist shops. A ski shuttle regularly passes through the town, onward to Gaustablikk. Unfortunately, there is no railway.

Norway is famous for its cross-country skiing. The Gaustablikk skicentre offers over 85km of groomed cross-country trails.North of the Rjukan valley, the summit of Piggnatten (1,136m) can be accessed via the Krossobanen uplift.The Telemark is the Northern Europe’s largest mountain area, containing the Hardangervidda National Park. It is popular with locals and tourists alike taking part in a range of snow sports.The lake at Sandvass (1089m) is frozen for 6 months of the year and popular with locals ice fishing.The Krossobanen uplift provides access to the Telemark plateau at the Gvepseborg station (890m). This provides access to winter walking, snowshoeing, cross-country skiing and ski-touring.Perfect conditions for winter walking, snowshoeing, cross-country skiing and ski-touring.Mid-winter afternoon sun over the Telemark, north of Rjukan on the Hardangervidda plateau.


Snowshoeing has been a long-established form of travel for over 5000 years. A latticework of bindings surrounded by a wooden frame provides a flotation device when hiking or trapping in soft, deep snow.

Modern snowshoes are lightweight, reasonably priced and very easy to use, making it a suitable activity for everybody.

Rjukan offers multiple areas to snowshoe, the most practical one starting from the ski resort at Gaustablikk. Here you can make use of the sides of the groomed cross-country pistes, or follow the many marked trails surrounding the resort. This is a perfect location for beginners.

Snowshoeing in and around the Rjukan Gorge is equally easily accessible. It is important to note that when snowshoeing off groomed pistes, it is strongly recommended to carry and know how to use an avalanche transceiver, probe and snow shovel, alongside sufficient clothing, a map and a compass. Experienced snowshoers can make use of the free detailed Norwegian online mapping, where circular routes can be planned in advance. There are numerous car parks aligning the valley, as well as the uplift at Krossobanen.

The Krossobanen uplift was built in 1928 and provides the perfect opportunity for the intermediate snowshoer to access the south-eastern edge of the Hardangervidda plateau. Many routes are marked at the 890m lift station at Gvepseborg, making use of some groomed trails, alongside trailblazing new routes. A particularly good circular route from here incorporates the summit of Piggnatten (1136m) and the lake that is frozen for six months of the year at Sandvass (1089m).

For the experienced snowshoer, a short circular route can be planned near the famous ice-climbing sight of Krokan, providing an insight into the terrain experienced by the heroes of Telemark. Leaving the car park at the village of Fosso, make use of one of the two bridges that cross the gorge, to ascend the mountainside using either the footpath or the forest road. Trailblazing and a good knowledge of walking in the winter environment is needed to rejoin the opposing path, making use of a map and compass to ensure you complete the circuit.
