Hetta is the main village in the municipality of Enontekiö in the north-west part of Finnish Lapland. It is also the municipality's administrative centre and the start or end point of the standard trekking / skiing route across the Pallas-Yllastunturi National Park.
Enontekiö Airport is located 9 kilometres west of Hetta but no longer has regular scheduled flights. Otherwise, the nearest Finnish airport is Kittilä, c. 2 hours South although Alta, in Norway is a similar distance. Tromso, Kiruna and Rovaniemi are all a similar distance although flying into Tromso is a good option if your intention is to spend the majority of your time in the far West of Enontekiö, in the village of Kilpisjärvi.
