To get to Nanortalik, visitors need to take a domestic flight from Keflavik Airport in Iceland to Narsarsuaq Airport in southern Greenland, followed by a helicopter ride to Nanortalik. The total travel time is around 4-5 hours and costs approximately $1000-1500 per person.
If you have more time, you can add an extra hike to the nearby Kangikitsoq mountain, which offers stunning views of the fjords and glaciers. If you have less time, you can skip the boat tour or explore town center in less detail.
