Not familiar with an Adventure Lab? Let me help you out! First, Lab Caches are an experimental geocache type typically played at Mega-Events. These caches count towards your geocaching statistics and total finds. In contrast to other cache types, Lab Caches are not required to have a container and can also be located indoors. This allows Lab Cache owners to innovate and test new ideas to make geocaching even more fun!
The Geocaching Adventure Lab app is a new way for geocachers to find and log Lab Caches. The Adventure Lab app runs on Android OS or Apple IOS. Visit your mobile device app store and download it. When you launch the app, you will find a world of Adventure Lab experiences and where they are located, relative to your position.
