​Geocaching is a great way to combine the outdoors and the techno-age -- experience high-tech scavenger hunting and travel through Oakland County to see what's hidden beyond your backyard! 

Geocachers can explore beautiful woodlands and downtown areas to discover caches (pronounced "cash") using a Global Positioning Unit (GPS). A caching adventure can last from an hour to a full day.  Caches exist in urban and backcountry areas. Coordinates can be found online at

Once you select a cache and enter coordinates into the GPS, the receiver indicates the distance and direction of the cache. When you find it, sign the logbook, take a prize, leave a prize, re-hide the cache and venture on to the next one!

The geocaching craze started in 2000 and is now a hands-on adventure for more than 750,000 people worldwide. It's an activity for all ages and abilities, from a lone cacher to an entire family or group of friends.

Getting Started
Geocaching is an outdoor recreation option available year-round at eight Oakland County Parks: Addison Oaks, Catalpa Oaks, Highland Oaks, Independence Oaks, Lyon Oaks, Orion Oaks, Rose Oaks and Waterford Oaks. Park Maps (link to maps filtered list)

What is Letterboxing?
Letterboxing combines treasure hunting, art, navigation and exploration. It began in Dartmoor, England when a gentleman simply left his calling card in a bottle by a remote pool on the moors.

Here's the basic idea: Someone hides a waterproof box somewhere in the park that contains a logbook and a carved rubber stamp. Participants seek out these hidden letterboxes by cracking codes and following clues. When the hunter successfully deciphers the clue and finds the box, he stamps the logbook in the box with his personal stamp, perhaps writing a note about his adventures finding the letterbox, and stamps his personal logbook with the box's stamp. To learn more, visit
