At the Lindlingalm, after about 200 m, you turn left up via Birgl to the Schusterscharte, from where you can recharge your batteries.

At Teufelssprung, after about 4 hours walking time, a short rest is recommended before you reach the probably most beautiful part of the hike, the ridge hike from Teufelssprung to Gamshag.

Circular hiking trail from Lengau to the head of the valley of Saalbach Hinterglemm

This panoramic circular trail leads us from Lengau to the managed alpine pastures at the end of the valley.  On the way we have a wonderful view of the valley and also of the surrounding mountains like Staffkogel, Tristkogel, Gamshag, Schusterkogel and at the end of the valley you can see the Hochkönig.

This route encompasses the runnable outer borders of San Francisco. It includes the Golden Gate bridge, because this route would not be complete without it (note that you only have to run over the bridge once). At times this route goes into Daly City on the southern edge of SF, as the straight line border of SF cannot be followed, and follows the most popular routes among the bottom.
