$Once you've driven up to Brunnialp, you should definitely make the short climb to Trogenalp; the view is very beautiful. Like Brunnialp, there's also a small alpine restaurant here.

A very nice little alpine restaurant at the back of the Brunni Valley. A fairly large selection. The gingerbread satisfies the hunger very well.

After you have pedalled up to the Oberfeld, the descent finally comes. Right at the beginning, it leads across a meadow.

Oberfeld is the end of the mountain bike route. From here you can only go further up by pushing. So it's time to enjoy the phenomenal view and get ready for the descent.
