Geocaching is a fun way to merge technology and outdoor exploration. Folks hide a cache, typically a small container with a log-book and people use a GPS receiver or smartphone app to find it. When a cache is found, the finder goes to www.geocaching.com or to the 'Found' feature on their app to log the visit, maybe upload a photo, and read what others said about it.

Most state parks have at least one cache. They range from simple and quick grabs that are easily reached from a trail to challenging multicaches that require collecting information at one site before moving on to the next. Others, virtual caches, earth caches or waymarks, have no cache box; geocachers usually must log visits to this type of cache by providing information obtainable only by visiting the site.
