From the summit cross of the 1,670 meter high Steinplan you have a great view over green valleys to snow-capped Alpine peaks. You can easily reach the summit by bike and as a reward you can stop off at the Steinplan refuge, which is just below the summit.
The Steinplan is Knittelfeld's local mountain and can be easily reached from several sides, both on foot and by bike. Once at the top you have a great view of the Mur valley.
