Geocaching is an outdoor activity using a Global Positioning Sysem (GPS) device to hide and find containers (geocaches) left by others. Usually a cache is a waterproof container with a logbook inside. Once a person finds the cache, they enter the date it was found and place it back exactly where they found it.

Geocaching Regulations
Since April 30, 2009, MDC has permitted geocachers and letterboxers who acquire a Special Use Permit to place caches and letterboxes on many conservation areas. You do not need a Special Use Permit to search for caches on conservation areas, only to place them.
Thanks for using and enjoying your Missouri Department of Conservation areas!
If you need a special use permit, get more details and apply.
