From Blosbrücke (Hopfgarten) follow the trail, in a few hairpin bends, into Zwenewaldtal. From here you get a lovely view to the Glockner massif. The road proceeds south, almost flat, in this lovely altitude valley, past Zwenewaldalm up to Bloshütte. From Bloshütte head into the valley via the Fenstersteig to Geigensee. There are a few rocky sections to tackle in this area.
