We started our trip from Aittajärvi on Lake Suomujoki. In the south of Finland, September is still a warm summer month, while autumn had already arrived in Lapland.
On top of the fells, our faces were lashed by horizontal rain but it was worth it for the stunning views of the Sarvijoki River.
Hiking in Urho Kekkonen National Park is safe. There are plenty of bookable and freely available huts for overnight stays, as well as saunas; the area also has lots of water and wood for cooking.
