About Rjukan Falls

Rjukan Falls (Rjukanfossen) is a prominent waterfall beside the town of Rjukan in Tinn municipality, Telemark county, Norway. The falls and the river’s energy were central to the area’s industrial development.

The falls form a striking cascade next to the town and are a common sight on walks around Rjukan; they are visible from nearby viewpoints and riverside paths. The area attracts visitors interested in industrial heritage and landscapes shaped by hydroelectric development.

The availability of falling water in the Rjukan area led to large-scale hydroelectric projects in the early 20th century that supported Norsk Hydro’s industrial operations. The local landscape and infrastructure were transformed by dams, power stations and transport built to exploit the river.

The waterfall sits on the Rjukan river close to the town of Rjukan in Telemark, southern Norway; the town grew around the industrial facilities that used the river’s power.

  • Industrial heritage: The waterfall is adjacent to the town of Rjukan and was a key reason for early 20th-century hydroelectric development in the area, which powered local industry.

Getting There & Around

How to Get to Rjukan Falls

Rjukan Falls (Rjukanfossen) is in the town of Rjukan in Telemark; the waterfall is within or immediately adjacent to the town so once you reach Rjukan it’s a short walk from the town centre. By car the usual approach from Oslo is roughly 150 km (about 2.5-3 hours) driving west - the route uses the main trunk roads out of Oslo and the connections toward Rjukan (major links include E134 in the Notodden/Notodden-Rjukan direction and local roads into Rjukan). Regional buses also serve Rjukan from surrounding towns; once in Rjukan follow local signs or ask locally for the falls (a short town-centre walk).

Tips for Visiting Rjukan Falls

  • Aim for late spring (May-June) to see Rjukan Falls at or near peak flow from snowmelt; winter offers dramatic ice formations but can limit safe access.
  • Start from Rjukan town center where marked paths and viewing platforms provide the most direct, signed approach to the falls; local tourist information in Rjukan can point to the best viewpoints.
  • Combine your visit with nearby Vemork (the old hydroelectric plant and museum) for historical context that many visitors miss when they only see the waterfall.
