The father of Leif Eriksson (who discovered North America around 1000 BC), Erik The Red, colonized the area around 985 BC with other Vikings from Iceland. They settled in what today is the Inuit settlement of Qassiarsuk (then 'Bratthalid') which is on the trail. There you can, among other things, see the reproduction of Thjodhild's church and a Viking house in an area with several Viking ruins.
Several sheep farms are scattered around in the area and the climate in the fjords is mild and the much lusher than the rest of Greenland with grass fields, bushes and a few trees here and there. The landscape on the first stretch is almost flat, but when approaching Narsaq the terrain gets more mountainous and the nearby peaks rise up to 1700 meters.
If you want to avoid the river crossing between Narsarsuaq and Qassiarsuk you can book a boat transfer with Blue Ice Explorer.

The route is quite safe so the only real risk factor is the river crossing at the northern end of the fjord between Narsarsuaq and Qassiarsuk (Brattahlid) after heavy rain. You should bring ropes in case of strong water flow.
Alternatively you can book a boat transfer to Qassiarsuk to start the hike from there.
There is a theoretical risk of encountering a polar bear, but it's extremely low. Please read our guide for how to deal with polar bear encounters - just in case!
