From Klostertal, take the bus line 720 to Langen am Arlberg and continue with the bus line 750 to Lech am Arlberg. From Lech am Arlberg, a hiking bus runs in to Spullersee. The mountain tour starts at the bus stop at Spullersee. Follow the hiking trail signs in the direction of Gehrengrat/Formarinsee. The first stretch takes you along the Spullersee circular trail, before the trail turns right after a short while. Follow this hiking trail over the Grüner Bühel, past the Dalaaser Schütz, up to the Gehrengrat. Briefly follow the ridge to the northwest before the steep and loamy trail leads down towards the Steinernes Meer. The trail then runs relatively flat over the Steinerne Meer to the Schafjöchl (2,090 m), which lies below the Formaletsch. From here the trail now leads down to the Freiburger Hütte. After a cosy stop for refreshments, you then descend via the rocky path (only for experienced hikers) to the bus stop of the hiking bus. This takes you back to Lech from the Alpe Formarinsee. The 750 and 720 buses take you back to Klostertal. For all hikers with stamina: You can also descend via the Stebok trail into the Klostertal valley to Dalaas - additional 2.5 h walking time.
