Hetta is the main village of Enontekiö and the northern end of the Hetta–Pallas trail in Pallas–Yllästunturi National Park.
At 68.4° N, Enontekiö (Hetta) lies under or very close to the auroral oval, so the aurora can appear even on quiet nights when the sky is dark and clear. Clouds are the biggest obstacle, so always check the cloud forecast above before heading out.
In late December Enontekiö (Hetta) has about 17 hours of darkness every night, around the autumn equinox about 8 hours and around the spring equinox about 8 hours; in mid-April still about 3 hours. See when to see the northern lights for a month-by-month guide.
