Set somewhere between orienteering and a treasure hunt, geocaching is an entertaining adventure game for GPS users. Participating in a cache hunt is a good way to explore an area, and to take advantage of the wonderful features and capability of a GPS unit. Caches have been set up all over the world by individuals and organizations and in their simplest form contain just a logbook of visitors. The locations are posted on the Internet and GPS users can then use the given coordinates to find the caches. Further information and a list of caches in the area around Dolgellau can be found here.
