Find a cache in the Waukesha County Parks!

Geocaching is a popular outdoors "scavenger hunt" that uses a global positioning system (GPS) device and internet-published coordinates to locate a virtual or physical cache. A virtual cache may be an amazing view; a physical cache may be a trinket or logbook in a plastic container hidden under some leaves.

Geocaching is welcome in the Waukesha County Park System when all the park guidelines and policies are followed – including paying the park entrance fees (when applicable) and parking in the appropriate designated areas.

Required: To place a physical or virtual cache, obtain prior written permission from Waukesha County Park System. 

• Read the Geocache Regulations 
• Apply for a Geocache permit for each cache location
• With each request form, enclose a map (eg. a Google map with each location marked)

Geocache Regulations

Types of Geocaching Allowed in Waukesha County Parks

• Virtual Caching (preferred):
Coordinates of stationary landmarks guide participants to the virtual cache. Virtual caches are verified only by e-mailed photos of the cache site.

• Physical Geocaching:
Participants seek a hidden -- not buried; do not break ground -- physical cache. A waterproof container stores the trade item or logbook; for a letterbox cache, there is usually a logbook and rubber stamp. Participants mark their personal logbooks with the stamp from the letterbox, and use their own personal stamp to mark the letterbox's logbook. For a micro-cache, a small container such as a film canister is used.

Basic Guidelines for Geocaching for all Participants

• You must abide by all Waukesha County ordinances.
• You must conform to the "Leave No Trace" outdoor ethics guidelines: take nothing but photographs, leave nothing but footprints.
• If you discover any illegal or hazardous materials in the cache, you must contact a Waukesha County Park System Administrative Office immediately at 262-548-7801.

Placement of a Cache

• To place a physical or virtual cache, you must have prior written permission from the Waukesha County Park System. For each cache location, complete a separate Permit Request Form and provide a map (eg. Google Earth or similar map) with each permit request.
• Applications for caches at Fox Brook, Fox River, Menomonee, Minooka, Mukwonago, Muskego, Naga-Waukee, and Nashotah parks, and Retzer Nature Center can be considered by management if placement of cache is within the trail right of way (ie. within five feet of the trail on either side) of established trails.
• Cache may not physically change the character of the site. This includes but is not limited to disturbing/excavating soil, cutting vegetation, moving logs, etc. You must use the natural terrain and site conditions to hide the cache.

Geocaching not allowed in:

• State Natural Area: Muskego Park hardwoods
• Sensitive Areas: Those areas the Waukesha County Park System staff determine cannot tolerate human traffic or disturbance which includes portions of the parks & greenways.
• The normal field of play at recreational facilities like sand beach areas, playgrounds, multipurpose sports fields, and more.
• Golf courses, campgrounds, dog exercise areas, mountain bike trails, or recreation trails (view here).
• Adjacent to birdhouses or bird nests. Federal law protects nesting birds and disturbing their nest is a federal crime.
• Areas with slopes greater than 5% incline. Caches may be allowed on the area above the slope or the foot of the slope.

Physical Cache Content

• The following items are not permitted in a physical geocache:
 - Food
 - Weapons of any kind
 - Illegal items such as drugs
 - Materials restricted from minors, such as, but not limited to, tobacco and alcohol
• The maximum capacity of any single physical geocache must not exceed one gallon
• All cache containers must be clearly labeled in large lettering with the word "Geocache" on the outside of the container, especially old ammo cans.
• All caches must contain your permit number inside the container.

Monitoring the Cache
Recommended: Four times per year. You are responsible for monitoring the cache regularly and reporting any vandalism or deterioration of property. If you discover any illegal or hazardous materials in the cache, you must immediately contact a Waukesha County Park System Administrative Office at 262-548-7801.

Moving or Removing a Cache

• To remove a cache, notify Waukesha County Park System via email of the removal. Include permit number, if applicable. No new permit required.
• Geocache permits expire after ten years; if you wish to extend beyond ten years, apply for a new permit. Without a new permit, you are required to remove and archive your cache once the permit is expired.
• A cache may be required to be moved if the Waukesha County Park System staff deems that the cache area is being over-used, or that volunteer trails are developing, or the site is set to be developed.
• A cache will be removed if the Waukesha County Park System staff determines that there is an unacceptable hazard to humans, an unacceptable level of damage to the environment, or it is not in compliance with policy. Waukesha County Park System shall make a reasonable effort to notify you of a removed cache. A removed physical cache will be stored for up to one week. If not claimed, it shall be disposed of as surplus property.
