Geocaching is an outdoor recreational activity that involves participants using a GPS device or smartphone to hide and seek containers, called "caches," at specific locations marked by coordinates. These caches can vary in size and often contain a logbook for finders to sign, as well as small trinkets or toys for trading. The activity promotes exploration and adventure, as geocachers search for hidden treasures in parks, forests, and urban areas. It encourages teamwork and problem-solving, making it a fun way for families and friends to connect with nature and each other while discovering new places.
