As you can see by the picture, some of the geocaches just have papers in them that you sign to say you found it and then put it back, others you can exchange the small token inside for one of your own. Just a warning, some Geocaches are very big, and some are super tiny and can be disguised as screws or bolts on a lamppost, so you have to be ready to poke at things to see if they are real.
It is a cheap way to get the whole family involved for a problem-solving adventure. Go to the Geocaching website or download their app and set your path.
Make sure you pack a tools-of-the-trade bag to include a pen, tweezers, a small mirror, gloves, and a stick to tap at things to see if they are the geo-cache. You must always replace the token you swap, so make sure you bring things like stickers, gumball style toys, or anything that represents your family.
Be cautious in areas with snakes and other venomous creatures and bugs and stay clear of anything on private property. You will be amazed at how many geo-caches there are. Young and old enjoy this treasure hunt.
