Oslo Gardermoen (OSL): The main international airport for Norway; from Oslo to Rjukan expect about a 3-4 hour drive. There are organized coach services (seasonal and scheduled) from Oslo and Kongsberg that serve Rjukan, with journey times typically around 3-4 hours.

Sandefjord-Torp (TRF): An alternative low-cost airport for southern Norway; travel to Rjukan from Torp is usually by a longer combination of coach and/or car (around 3-4+ hours) depending on connections.

By Train & Bus

Bus: Regular long-distance coaches and local buses link Rjukan with Kongsberg, Notodden and Oslo (operators include Vy and local carriers). Bus transfers from Kongsberg/Notodden typically take around 1-2 hours depending on origin.

How to Get Around Rjukan #

Rjukan’s centre is compact but built into steep terrain, so be prepared for uphill walks; many main sites are reachable on foot if you’re reasonably fit. Local buses connect Rjukan with Notodden and surrounding communities, and regional coach services run to larger hubs. Having a car helps for exploring trails and nearby attractions; during winter, check schedules for lifts and buses. Costs for buses are comparable to other Norwegian regional routes and are higher than in many continental European countries.
