A really nice and short walk (25/30 minutes) from Berghaus Zoll to Grossboda alp.
At the waypoint very close to the cache you'll have a beautiful view of the tops of Wisshorn (2,988m a.s.l.), Alperschällihorn (3,039m) and Teurihorn (2,973m).
From here you can keep on walking to the Tamboalp within 30 minutes to search for GC6PCY8 and GC2N9VP.
