The market town borders the Tauferer Ahrntal municipalities of Gais in the south as well as Ahrntal and Prettau further north. In the east, the municipal area comprises the Reinbach gorge and the slopes of the Rieserferner Group. Large parts are covered by the Rieserferner-Ahrn Nature Park, a protected nature reserve which extends to neighbouring Percha, Rasen-Antholz and Sankt Jakob in Defereggen in Austrian East Tyrol. West of the village of Mühlen, the Mühlwald valley stretches westwards up along the Speikboden massif to the Neves reservoir and the crest of the Zillertal Alps.
