Geocaching for Families

Caches are containers that have been hidden by fellow geocachers -- anyone can do it. The person who initially hides the cache posts its GPS coordinates on geocaching.com, which is how you know where to look. Caches are everywhere -- there are 900,000 worldwide! "We were surprised to learn that there are 1,300 caches hidden just in our small town," says Judie Churchill of Durham, New Hampshire.
