Griffen can be reached by motorway A2 (exit 273). You probably want to use the stairway (N46 42.230 E14 43.835) next to the church to get on top quickly (it will take about 10 minutes). The change in elevation is about 130 meters.
The significant foundation walls of the 15th century castle on top of the Griffner Schlossberg can bee seen from far away and are illuminated at night.
The cache is a small plastic container (about 7*7*4 cm). It is hidden behind a stone and therefore not visible. Please hide it well again.
