Two different routes lead from Prebersee up to Grazer Hütte. The route we suggest first leads flat along the Preberstraße to the signposted junction. If you wish, you can also start from that parking lot. The hiking trail is easy to walk and leads up to the Grazer Hütte via a forest path and trail. Alternatively, you can take the slightly longer route via the Halterhütte, which then leads to the Grazer Hütte at almost the same level. You can combine both variants to create a circular tour.
