To the north, west and southwest the municipality is surrounded by the Zillertal Alps. The main chain of these Alps at the head of the valley also forms the border with Austria. Amongst the most important mountains in the municipality are the Turnerkamp (3,418 m), the Hornspitzen, the Schwarzenstein (3,369 m), the Großer Löffler (3,379 m), the Wollbachspitze (3,210 m) and the Napfspitze (3,144 m). The ranges to the west and southwest, including the Speikboden massiv, separate the village of Ahrntal from Mühlwald in the Mühlwalder Tal. To the southeast are the Durreck Group, a subrange of the Venediger Group with the Durreck (3,135 m) and the Hirbernock (3,010 m) which form the boundary of the municipality of Reintal and its village of Rein in Taufers. Large parts of the Durreck Group are protected as part of the Rieserferner-Ahrn Nature Park.
