According to Wikipedia, it’s an outdoor recreational activity in which the participants use a Global Positioning System (GPS) receiver or mobile device and other navigational techniques to hide and seek containers, called “geocaches” or “caches”, anywhere in the world. In short, it’s a real-world treasure hunt using your GPS or iPhone—and it’s happening all around the Black Hills!
WHAT YOU NEED TO KNOW BEFORE YOU START
Difficulty Levels: each cache has a level from beginner to expert that will be marked on the owner’s profile. Make sure you and your explorer can handle the terrain and the size of the cache.
Where is the treasure? Not all caches have treasures in them–some just have a logbook. Read the comments below the cache profile to set your kids up with proper expectations.
One-for-One: only take one item from the cache. Children can take turns with taking and replacing items for each cache you visit.
