Geocaching is search with help from a GPS
Geocaching is actually the ancient treasure hunting, but here you go out of the GPS coordinates to find the treasure. It seems to have been invented in 2000 by Dave Ulmer, who had put a bucket of goodies in the forest. He mentioned the coordinates on a website about satellite navigation and invited people to search for the bucket. There was also the idea of getting something out of the bucket and stopping something new (and updating the log). After that it went fast and there are many geocaches hiding on the whole world. With websites to find the data of the geocache or even complete routes along different geocaches. The real fanatic has its own GPS device, but for the people who want to try it, it is also possible to use your mobile phone (often not as accurate as a real GPS) or you can rent a GPS at the local tourist office. The principle has not changed: you are looking for the treasure (geocache) and if you have found it, you will update the log and submit a new treasure. Meanwhile there are geocaches for the novice but also for the expert, where the treasure for the expert is often small, and which for the beginner is larger and easier to find.
