Geocaching
Geocaching can be compared to treasure hunting. Based on coordinates you start looking for a ‘cache’. This could be a very small box, but also a big case. Once you’ve found the cache you can write your name in the log. Some caches you can start looking for without any preparations, while with others you first have to solve a puzzle to get the right coordinates. Geocaching is fun for both adults and children.
