A small geocache container

The geocache itself can be anything from a container that can hold a small piece of paper, to a virtual cache where the place you visit itself is the geocache. Cache containers come in all sorts of shapes and sizes. Some may be obvious when looking at them, but most are not. For the most part it just has to be big enough to hold a slip of paper, or log, that people can sign. It can be a homemade container, or something that was purchased in a store. The best are the caches that appear to be a fixture that blends in with the environment. Common geocache containers include tupperwear, bison tubes, ammo cans of varying sizes, hide-a-key boxes, and other water tight containers.

A tricky geocache

There are other types of geocaches that actually take you to a place, called a Virtual Cache or Earthcache. Usually, for these types of caches there will be some questions to answer so that you can prove that you visited the site. These are often educational and/ or landmarks. Great when traveling. These geocaches can often be found without a GPS since they are usually taking you to a specific area.
