If you are flying to one of the Oslo airports, take the airport express bus to Oslo Bussterminal, and then you can travel with the bus operator ‘Nor-Way’ to Rjukan, usually changing once at Notodden. For up-to-date information, please refer to their website. On the bus from Notodden to Rjukan, ask the bus driver to drop you off at ‘The Old School’ and he will drop you off just after the hostel. Walk back 150m and the hostel is the yellow building on the left.
Our address is Knut Dahles veg 31, 3660 Rjukan, and you can find directions using google maps.
