A fun and very easy trail run — with minimal technical sections — from Brunnen to Fronalpstock, with a few extra meters added just for fun.
Stoos and Fronalpstock can be a bit touristy, so the trail turned into a surprisingly social experience — quite enjoyable overall.
Instead of doing an out-and-back to Fronalpstock, you can extend the route to Klingenstock and make it a loop. It adds 2–3 km and a bit of up and down, but the weather was turning today and thunderstorms were forecast, so keeping it simple was the better choice.
The trail starts and ends at Brunnen train station. You can also shorten it in Stoos or Fronalpstock — both have ski lifts (also operating in summer).
