+Geocaching is a real-world, outdoor treasure-hunting game. Dedicated containers, known as geocaches, are hidden throughout the world, publishing their coordinates as well as any other relevant information online. Participants then use public information to locate them in order to sign a logbook inside, proving that they have solved the mystery and successfully located the cache. As of 2026, there are over 3.4 million active geocaches worldwide.
