Geocaching, the present-day version of treasure hunting, involves signalling a desired geographical location with GPS coordinates. Geocachers are thus able to plan a route that will provide them an adventure in nature. The goal is to find the so-called caches, small boxes with GPS transmitters that were placed in strategic locations by other geocachers. To bring a symbolic "prize", they need to return the favour by leaving behind something for the other geocachers. Geocaching is a mixture of sport and leisure, and the Azores offer excellent conditions for this activity.
