Official State of Iowa Website Here is how you know


is the activity of hiding a geocache container from public view for the challenge of participants using a global positioning system (GPS) device and internet-published coordinates to then locate. Once located, the participants typically take an item from the geocache, replacing it with one that they contribute. There is usually a logbook in the cache that the finder can sign and date.

Rules and Regulations for Iowa State Parks and Recreation Areas

A Geocache Placement Permit Application must be filed and approved by the park staff before establishing a cache within Iowa State Parks and Recreation Areas.

1. The park staff will consider resources management, visitor safety and sensitive sites when determining sites and pathways for approval. A special event permit may be required if the geocache is part of an event of a day/weekend.

2. Caches are not to be placed in sensitive archaeological, historical or ecological areas such as historical buildings, caves, or locations that contain rare plant species. Prescribed burn units are generally considered to be off-limits for placement. Consider EarthCaches rather than physical caches in environmentally sensitive areas. Please clearly mark the outside with "Geocache" in block letters, along with Geocache name if space allows.

According to "An EarthCache is a special place that people can visit to learn about a unique geoscience feature or aspect of our Earth. EarthCaches include a set of educational notes and the details about where to find the location (latitude and longitude). Visitors to EarthCaches can see how our planet has been shaped by geological processes, how we manage the resources and how scientists gather evidence to learn about the Earth.

3. There is no time limit for placement, however, please be respectful in regards to placement and ongoing maintenance of your Geocache. The Department of Natural Resources reserves the right to terminate this approval for placement of a geocache container on state land for any reason at any time. All local and state laws apply.
