Hochzirl - Pleinerweg - Solsteinhaus (Alpenverein Route 213) The quickest way to reach Solsteinhaus is from the train station in Hochzirl along the signposted path across the Pleiner stream and the Solenalm alpine hut. The route takes you along hiking trails and forest paths until crossing the upper stream at 1,417m above sea level. It's then a steep. winding track to the Solenalm (1,643m, unserviced), and a wonderful view of the Erlspitze and Solstein peaks. From here, it's northwards above the Erltal valley, before crossing the stream in a north-easterly direction, following the curves to the long-visible alpine hut.
