Geocaching on Fehmarn

This modern form of treasure hunt using GPS is also very popular on Fehmarn.
There are some 200 caches on Fehmarn. The "treasures" contain a log book for entries by participants and often a small item for trading. The "treasure" is then replaced in its hiding place. This GPS-led treasure hunt also takes participants to otherwise less frequented areas of the island. GPS coordinates are available here.

"Water as a Landscape Gardener" is a GPS bicycle tour for children's and youth groups. Information about the "Fehmarn-Rallye", compiled by confirmation candidates of the Petersdorf parish, is available here
