The Niederen Tauern are, same like the big brother Hohe Tauern, divided into different sub groups:
There are the Radstädter Tauern with nice splitboard beginner routes, Rottenmanner / Wölzer, the Seckauer Tauern and the Schladminger Tauern.
Starting points for splitboard touring in the Schladminger Tauern are Radstadt, Schladming and Murau. Highest peak is the Hochgolling (2862m).

4 splitboard routes
