Nybyen is reached from central Longyearbyen, which has the main airport with daily flights from Tromsø and Oslo. From the airport, take the shuttle bus to town and continue on foot, by local bus, or by taxi for the final 2 km up the valley. In winter the road can be icy; in summer it is a flat, easy walk.
There is no public transport out of Nybyen itself — onward travel is by snowmobile, dog sled, ski, boat, or organised tour.
