Riksgränsen is on the Malmbanan railway between Kiruna and Narvik, and the station is within walking distance of the slopes. Trains make it far easier to reach than most Arctic mountain resorts, especially if you are crossing northern Sweden and Norway without a car.
By road, the E10 runs past Riksgränsen and continues over the border toward Narvik. Winter conditions can be serious, so check weather and road information before driving.
