What are Geocaches?

Geocaching is a real-world, outdoor treasure hunting game using GPS-enabled devices. Participants navigate to a specific set of GPS coordinates and then attempt to find the geocache (container) hidden at that location.

What do I need to go geocaching?

The only necessities are a GPS device or a GPS-enabled mobile phone so that you can navigate to the cache, and a free Membership. You can find out more about geocaching at

 How do I find the cache and what should I do once I've found it?

There are many things to know about searching for a cache. For instance, did you know that there is a slight "error" to every GPS device due to technological limitations? Your device can get you close to the cache, but there are a number of things to consider as you get closer to the cache location.

 When you find the cache, sign the logbook and return it to the cache. You can take an item from the cache if you like - just make sure to leave something of equal or greater value in its place. When you are finished, put the cache back exactly as you found it, even if you think you see a better spot for it. Finally, visit the geocache website to log your find and share your experience.

 What does a geocache look like? 

Geocaches vary greatly in size and appearance. In the field you will see everything from large, clear plastic containers to film canisters to a fake rock with a secret compartment. So, how do you find the cache?

The first step is to get a general idea of the cache's size. The size is shown on each cache page. A general overview of the cache size graphic is found below. Please note that these are just examples; sizes can vary.

 Micro - Less than 100ml. Examples: a 35 mm film canister or a tiny storage box typically containing only a logbook or a logsheet. A nano cache is a common sub-type of a micro cache that is less than 10ml and can only hold a small logsheet.
 Small - 100ml or larger, but less than 1L. Example: A sandwich-sized plastic container or similar.
 Regular - 1L or larger, but less than 20L. Examples: a plastic container or ammo can about the size of a shoebox.
 Large - 20L or larger. Example: A large bucket.
 Other - See the cache description for information.

The Basics

Geocaching is an outdoor activity that operates using the Global Position System or GPS for the navigation element.  This means that a smartphone, tablet or even a specialist GPS tracking gadget is needed for the game and it is taking place around the world.

The game is a modern, high tech version of a game known as letterboxing.  Going back over a century, this game used landmarks and clues hidden in stories to send gamers around a location.  The idea of making it modern and tech-based came when GPS was no longer just selectively available back in 2000.  The new, improved system could accurately locate a small box and the first one was created by Dave Ulmer of Oregon.  The original bucket contained software, videos, books, food, money and even a slingshot and has been logged as discovered twice.

Geocaching for Children

If you and your kids love a good treasure hunt, then there you will also likely love geocaching.  Described as high tech treasure hunting, this is a great activity that takes everyone outdoors, gets them active and can be done as a family or with a group of friends.  So what is geocaching and where are the top spots to enjoy it?
