In its northern tip, Enontekiö is the only Finnish municipality that includes part of the Scandinavian Mountains. Through that and through its location in the far north of Finland, it is geologically and scenically very different from the rest of the country. Halti, the highest mountain of Finland with a height of 1,324 m, is located in Enontekiö, together with all 21 other mountains higher than in the country. Besides Haltitunturi, probably the best known and scenically most distinctive mountain is the Saana with a height of , which rises above the village of Kilpisjärvi. The southern part of the municipality is less mountainous, but some single fjells (tunturi, which means hills towering above the timber line) rise above the otherwise rather flat surrounding area. Below, a part of the Pallastunturi-Ounastunturi-massif extends into Enontekiö's territory.
