Transportation The Qassiarsuk area has a relatively extensive network of traversable dirt and gravel roads, totalling over 80 kilometers and requiring DKK 500,000 annually for service. The roads are mainly needed for the sheep farming. The longest stretch of road connects the sheep farms of Qassiarsuk with the airport of Narsarsuaq, around 50 km. The roads are generally of poor construction, lacking crossfall for drainage, and using softer sandstone instead of harder granite, creating severe dust problems in the summer. For general transportation all-terrain vehicles are recommended. Driving between the airport and Qassiarsuk is hard since there is no bridge over the glacial Narsarsuaq river and crossing it is difficult due to deposits of
silt quicksand the river carries from the
Greenland ice sheet (). All vital transportation at Qassiarsuk is by sea, with boats linking the settlement to
Narsarsuaq Airport, home to the only international airport in southern Greenland. The airport primarily functions as a transfer point for passengers heading for the
helicopter hubs of
Air Greenland in
Qaqortoq and
Nanortalik. Qassiarsuk does not have its own
heliport. == Economy ==
