How well you can do the Hausberg loop depends on the current snow conditions. Most of the time, the route described is easy to walk and protected from avalanches.
Nevertheless, snow reports and weather reports should always be obtained before a snowshoe tour, as well as current information on the nature of the path, e.g. from your accommodation, the tourist information center or hiking guides who also offer guided tours.
At the time of the snowshoe hike described in this article, at the end of January 2017, the last snowfall was a few days ago, the German Weather Service regularly reported icy records with Reit im Winkl as the coldest place in Germany. This made the path very easy to hike.
