Geocaching is an outdoor treasure hunt that combines hiking and high-tech. Explorers use sophisticated—but easy to use—global positioning system (GPS) devices to search for hidden treasure caches.
How to do it
1. Get the cache coordinates. Log onto a website to get a list of waypoints or coordinates that pinpoint where caches are hidden. These coordinates can be entered on a handheld GPS unit.
2. Locate the cache. Use a GPS unit to see your location in relation to the hidden cache, and follow the signal toward the cache.
3. Take or leave treasure. A cache is usually inside a waterproof container of some sort, like a water bottle or an ammo can.

There may be a logbook inside for you to sign, and often there are little trinkets left by previous players. (No food, please—food is not allowed inside geocache containers!) Geocachers remove the loot and replace it with other cool stuff for future geocachers to find. Leave something in the cache yourself if you'd like.
4. Share the fun. Visit geocaching.com to log your finds and share messages about your geocaching experiences.

Geocaching rules and ethics
When you are geocaching, always try to tread lightly on the land so you minimize the impact of your activity on the environment. Any caches in Minnesota state parks or on state trails have been placed above the ground, and in relatively well-traveled areas.
- Never remove a cache, or relocate it even a little bit. Leave the cache exactly how you found it so others can have the fun of finding it too!
- Observe all laws and respect property rights.
- If you are geocaching in a Minnesota state park, know and follow the park's rules.
- Be considerate of others and avoid causing disruptions.
